SMS Marketing Software

A few API endpoints behave differently than the docs imply, so the first time I wrote a script around them I got tripped up. Once you learn the quirks it’s manageable, but a more complete, detailed API reference would really help. I’d also love the option to activate newly created campaigns via the API, instead of having to switch them on manually in the dashboard.

One other small thing: warmup status and account health information could be surfaced more clearly in the UI. Right now I end up cross-checking a few different views just to get the full picture for a mailbox. Review collected by and hosted on G2.com.

Before Instantly, I was stitching together a few different tools for mailboxes, sequences, and replies. That meant constant context switching, plus a lot of small details slipping through the cracks. Having everything in one place lets me spend my time actually running campaigns and talking to prospects, instead of doing platform admin. For an operation my size, that’s the difference between scaling and staying stuck. Review collected by and hosted on G2.com.

The main downside is pricing. Costs scale quickly as your contact list grows and as you add hubs or move into higher tiers, and several features I'd consider essential sit behind the more expensive plans, so the jump between tiers can feel steep for a smaller team. There's also a learning curve past the basics. Simple workflows are easy, but advanced automation, custom reports, and conditional logic take real time to figure out, and reporting itself is powerful but rigid. Customizing dashboards beyond the default templates is more limited than I'd like, and pulling a specific cross-object report sometimes means exporting data and finishing the analysis elsewhere. Review collected by and hosted on G2.com.

HubSpot solves the fragmentation problem of running marketing across disconnected tools. Before, our contact data, email campaigns, landing pages, and engagement history lived in separate systems that didn't talk to each other, which meant constant manual reconciliation and an incomplete picture of each account. Having everything in one platform gives me a full timeline of every contact's behavior before I reach out, so my outreach is better targeted and I waste less time chasing the wrong accounts. The workflow automation also solves the problem of leads and accounts slipping through the cracks, since triggered sequences handle reactivation and nurture without manual follow-up, which has saved me hours each week and made our pipeline far more consistent. Review collected by and hosted on G2.com.

One limitation I noticed is that the email editor can occasionally feel restrictive when trying to create highly customized layouts or advanced design structures. Small formatting adjustments sometimes require extra steps compared to more modern design-focused platforms.

I also experienced occasional delays while editing larger campaigns or updating scheduled emails. In some cases, preview formatting did not fully match the final delivered version, which can create inconsistency concerns during communication campaigns. Review collected by and hosted on G2.com.

Before using Constant Contact, communication workflows were handled manually through separate email tools, spreadsheets, and inconsistent contact-management methods. That created delays, repetitive work, scattered communication tracking, and difficulty maintaining consistent engagement with different audiences.

Constant Contact solved this by centralizing campaign creation, audience management, email scheduling, automation, analytics, and communication tracking into one structured platform. Instead of repeatedly creating emails from scratch or manually following up with audiences, campaigns could be duplicated, automated, segmented, and monitored more efficiently.

For example, newsletters, operational updates, event announcements, follow-ups, and scheduled communication workflows could all be managed from one dashboard while engagement metrics provided visibility into delivery, open rates, and interaction trends. That improved communication consistency and reduced administrative coordination effort.

The biggest benefit was improved organization, time savings, and better visibility into communication effectiveness without needing highly specialized technical expertise. Review collected by and hosted on G2.com.

The main drawback for us is the pricing. As our automation volume grows, the costs can increase quite quickly, especially for businesses managing multiple clients and complex workflows. With more competitors entering the market and offering similar capabilities at lower price points, it would be great to see Zapier introduce more competitive pricing tiers or higher task limits within existing plans. The platform itself is excellent, but the cost can become a significant factor when scaling operations. Review collected by and hosted on G2.com.

Zapier helps us eliminate repetitive manual tasks by connecting the different tools we use across marketing, sales, customer service, and AI automation. Instead of having team members manually transfer data between platforms, Zapier automatically synchronizes leads, updates CRM records, triggers notifications, and launches workflows in real time. This has reduced operational overhead, minimized human error, and allowed our team to focus on higher-value activities. As a result, we can serve clients more efficiently, respond faster to leads, and scale our operations without needing additional staff for routine administrative work. Review collected by and hosted on G2.com.

As our automations became larger, the workspace started feeling harder to organize, especially with lots of tags, lists, and workflows running at the same time. Some integrations also needed extra setup through tools like Zapier when we wanted more customized workflows. Pricing was manageable early on, but costs increased noticeably once our contact lists scaled. Support was decent for common issues, although more technical questions sometimes took longer to resolve.

The AI features are useful for smaller tasks like content ideas, but they still feel limited compared to standalone AI platforms. Review collected by and hosted on G2.com.

Before using ActiveCampaign we were handling email campaigns, lead nurturing and CRM follow-ups across separate systems, which created a lot of manual work and inconsistent tracking. ActiveCampaign helped centralize those processes through automation workflows tied to form submissions, page visits, and customer activity. It improved visibility between marketing and sales teams, reduced repetitive tasks and made campaign execution faster overall. The platform performance has been highly stable for us even when running our largest email campaign sends. The Google Analytics integration also helped us better understand engagement and conversion behavior, while the built in AI tools save some time during campaign setup by helping with subject lines and content suggestions. Review collected by and hosted on G2.com.

At the start, it took some time to prioritize the right segments and customer journeys, especially while managing multiple use cases across different client needs. That said, once we aligned with the Insider team on a few quick-win use cases, the process became much more structured, and it was easier to scale into more advanced scenarios. Review collected by and hosted on G2.com.

Insider One helps us turn growing site traffic into stronger conversion and retention results for the Shopify brands we support. It lets us build more relevant customer journeys based on visitor behavior, purchase intent, and lifecycle stage, rather than relying on static storefront experiences.

This is especially valuable when we need to promote priority categories, improve cart recovery, encourage repeat purchases, and tailor messaging to different audience types. It also helps us connect marketing and onsite activity to measurable business impact, so we can assess performance more clearly and optimize client strategies with greater confidence.

Overall, Insider One helps us move from generic ecommerce experiences to more adaptive, conversion-focused customer engagement. Review collected by and hosted on G2.com.

Using lemlist for our "Pets and Patriots 250" public event was a complete game-changer. We were organizing a massive celebration for the 250th anniversary of the United States, featuring a car show and live entertainment in partnership with the Illinois Department of Veterans Affairs and Rover Rescue. With limited time and resources, setting up manual follow-ups would have been nearly impossible. Lemlist allowed us to easily launch automated cold email outreach targeting VFW and Legion Posts, regional car clubs, and pet rescue affiliates, making it simple to manage campaigns and schedule time directly from responses.

The customer support is also incredibly human. Before upgrading my account, I had 500 credits, but they unexpectedly dropped to a lower amount after I transitioned to the paid tier. I reached out to support, and a representative named Lena graciously credited them back to me. Her swift and kind assistance completely won me over.

The results of our outreach speak for themselves. The event was an enormous success, leading to an official partnership with the Department of Veterans Affairs, sponsorship for a nationwide car show circuit, and the financial backing to launch a pet supplies marketplace for American brands. Because of the impact of these campaigns, I have even been approached by business leaders, entrepreneurs, executive directors, and international figures to consult on their own initiatives.

The only downside is that the cost per lead is quite expensive compared to other lead generation solutions on the market. However, if you need a reliable solution to accomplish high-quality, 1:1 lead generation that builds real partnerships, lemlist is well worth the investment. Review collected by and hosted on G2.com.

The main problem lemlist solved for me was having too little time and too few resources to handle a massive email outreach campaign. I was organizing a major public event called Pets and Patriots 250 to celebrate America's 250th anniversary, which featured a car show and live entertainment in partnership with the Illinois Department of Veterans Affairs and Rover Rescue. I needed to send cold emails to VFW and Legion Posts, regional car clubs, and pet rescue affiliates, but following up with all of them manually would have been impossible. Lemlist fixed this by letting me easily set up automated email campaigns and follow-ups, and it allowed me to schedule time with people directly through their responses.

This benefited me by turning that automated outreach into incredible, real-world success. Because the platform helped me manage high-quality 1:1 lead generation so easily, my event was a massive triumph. It led directly to an official partnership with the Department of Veterans Affairs, sponsorship for a nationwide car show circuit, and the financial backing to launch a new pet supplies marketplace for American brands. The outreach was so professional and effective that kings, queens, business leaders, entrepreneurs, and executive directors have now approached me to consult and partner with them on their own initiatives. It completely solved my time problem and unlocked massive growth for my business. Review collected by and hosted on G2.com.

As easy as it is to use, as someone who doesn't have the most email management or CRM experience, there is a lot to see when you navigate through and sometimes I worry we aren't using all the features to our advantage. Review collected by and hosted on G2.com.

It is helping us drive sales, awareness for new collections and collaborations and gives us a way to track our customers and it syncs with Shopify so we're able to easily segment out our list. Review collected by and hosted on G2.com.

As I mentioned before, the pricing had been the main reason why I haven't had the chance of using Braze in my Marketing career so far. While it's definitely competitive when measured against equal calibre products, it can still be a little bit intimidating, especially for companies that are looking to commit to a platform for years to come.

CONS:

- In-app and content card channels priced separately

- Separate one-off onboarding fee

- A handful of learning materials locked behind a paywall Review collected by and hosted on G2.com.

Creating complex automated journeys to cater for multiple lifecycle stages for a highly segmented user base. Introducing possibilities for deep personalisation via liquid tags, creating content blocks to automate the better part of template creation. Review collected by and hosted on G2.com.

The AI integration could be improved, and the output could be more helpful overall.

This isn’t a major dislike, but having more direct AI features built into the dashboard—especially while designing emails and creating campaigns—would make the experience smoother and more useful.

The performance tracking interface of the campaigns can be better and more explained. Review collected by and hosted on G2.com.

The platforms makes it easy to execute and track outbound marketing efforts within few clicks.

The setup is easy and the features are well traversable.

The pricing makes it a more better tool with a lot of integrations available to connect along with exports and analysis of the data.

For me it is making my schedule more easier with the campaign scheduling, easy designing and simple tracking of the campaign that saves a lot of my time with priority support that listens and help in terms of any fault. Review collected by and hosted on G2.com.

I think the pricing can become a drawback as your contact list grows or as you need access to more advanced features. For smaller organizations or nonprofits, it can feel like the useful tools are spread across different plan levels, which makes it harder to know whether the cost is worth it.

Another downside is that design customization can sometimes feel limited. The templates are helpful, but making emails look exactly the way you want can take more time than expected. Review collected by and hosted on G2.com.

Intuit Mailchimp Email Marketing is solving the problem of managing consistent communication with a large audience. Instead of manually sending updates or trying to track contacts across spreadsheets, emails, and different systems, Mailchimp gives us one place to organize contacts, create campaigns, send updates, and review engagement.

It benefits us by making communication more professional, organized, and efficient. We can send updates to donors, volunteers, partners, and community members in a way that looks polished and is easier to manage. The templates and campaign tools save time, while the reporting features help us understand who is opening emails, clicking links, and engaging with our content.

Their really isn't to much I dislike about texedly. The only thing I could really think of is the price and maybe having benefits for using it more. Because it does cost 20 a month to send out about 500 texts or 250 long texts and at scale that could get pretty pricy. Review collected by and hosted on G2.com.

The problem they are solving for us is definitely customer retention %. We are using them to text out marketing deals for certain days to increase business and we are using them to promote our business which is going very well so far. We are still in the early stages of this but so far it's pretty good. Review collected by and hosted on G2.com.

This is only a minor irritation, but it's the only thing I can think of. When I've downloaded an image and want to upload it into the email builder, I can't just drag and drop it -- I have to search for it in my downloads folder (or wherever I'm up loading from). I'd love to see drag and drop added to just make this process a little quicker and more efficient. Review collected by and hosted on G2.com.

With Flodesk, I'm able to do so many things with only one platform, instead of having to manage (and pay for) multiple platforms. I do all of my email newsletters and marketing with Flodesk, manage my lead magnet opt-ins on my website, have a checkout integrated right into any offers I want to make, and manage my Instagram link-in-bio all in one place. And it all works like a charm. I'm not the greatest with technology, but Flodesk makes it so easy. It is by far the easiest and best email marketing platform I've used.

The email editor occasionally takes a few extra seconds to load when working with larger templates. I also had to spend sometime understanding how certain automation settings work when I first started using the platform. It wasn't difficult, but there was a learning curve.

EngageBay has made my life easier. Before using EngageBay, managing email campaigns and inquiry forms involved several separate tools and a lot of manual work. Now I can create landing pages to collect inquiries, segement contacts into lists, and send targeted email campaigns from the same platform.

For our business, this has made it easier to stay in touch with our prospects, follow up on inquiries and keep communication organized without spending as much time on manual tasks. Review collected by and hosted on G2.com.

So far, the only thing I’ve found that felt truly like Sender’s fault was their customer service chat. It took a bit longer than I expected, although the wait time was still reasonable. The bigger issue wasn’t the delay, but how robotic the support agent came across. The grammar was flawless, but the replies felt overly calculated and not very human. I’m still not convinced it was a real person, and I even asked whether it was human. I was intentionally casual and laid-back, and “Lucas” didn’t respond very warmly. Unfortunately, that’s the impression Sender has left me with for now. Review collected by and hosted on G2.com.

What are the problems Sender.net is solving*

this question felt odd reading...

Anyways, Sender is helping me with a highly customizable email intake form that I can then send emails to engage my list and track engagement with the content so I can target who on my list is more likely to buy in to my service. Review collected by and hosted on G2.com.

Some of the UI is a little clunky. For example, the base font constantly reverts back to Arial (very annoying!), you can't overwrite copy and keep the formatting, and I'd like to see more elements available (i.e. spacers)

In terms of reporting, it's a little more basic/limited than I'm used to. Hopefully the AI integration will help with this - for example I can't easily see how many users are active on site each day, Review collected by and hosted on G2.com.

Omnisend isn't solving a materially different problem to what we had prior to onboarding, but it is allowing us to build a robust operation across email and SMS. Review collected by and hosted on G2.com.

I don’t have anything significant to mention here because we have been extremely happy over the years with ContactPigeon. I remember that I used to find the features overwhelming, but I always had help when I needed something. Review collected by and hosted on G2.com.

ContactPigeon allows us to handle multiple marketing tasks in one place, from email campaigns to automation and engagement tools like push notifications and pop-ups. It simplifies our workflow and saves us time so that we can be more efficient and productive. It has also helped us stay organized and see better results. Review collected by and hosted on G2.com.

The scheduling flexibility could be better. If you want granular control over send windows, specific time zones, custom intervals between messages, you're working around the tool more than with it.

Reporting is also fairly surface-level. I'd like deeper visibility into what's actually driving replies, not just open and response rates.

Not dealbreakers, but there's room to grow on both fronts. Review collected by and hosted on G2.com.

Cold outreach on LinkedIn is tedious at scale. Writing personalised messages one by one is not a real option when you're managing multiple pipelines across different offers. Sendpilot removes that bottleneck.

The benefit is straightforward: more conversations started, less time spent starting them. I'm not sacrificing personalisation for volume, which was always the tradeoff before.

For a solopreneur, that's not a nice-to-have. It's the difference between consistent outreach and none at all. Review collected by and hosted on G2.com.

There’s a learning curve

The interface is simple, but it does take a few days to fully grasp how to use Sheets, merge tags, and campaign scheduling. Thankfully, the GMass blog and help docs are solid. Once you’re in the flow, it’s second nature.

It’s not the cheapest option

At $25/month, GMass might seem expensive compared to some email tools. But considering the features, flexibility, and Gmail-native experience, it more than pays for itself. Especially when you factor in saved time and increased deliverability.

Test your emails first

Always add yourself to the Sheet and run a real test. Occasionally, merge fields don’t populate as expected…not often, but often enough that you’ll be glad you checked. It’s a quick fix that avoids awkward sends. Review collected by and hosted on G2.com.

Let me be blunt: If you send cold outreach emails to grow your network, run affiliate programs with dozens (or even thousands) of partners, coordinate JV promotions, follow up with podcast guests, onboard new clients, or just need a smarter way to communicate at scale, GMass might be your secret weapon. Whether you’re a solo creator managing all your email yourself, or part of a team running large-scale affiliate campaigns, GMass makes it easy to send high-performing, personalized emails directly from Gmail. It replaces patchwork tools, improves deliverability, and saves hours by making mass email feel one-on-one. Review collected by and hosted on G2.com.
