"Easy to Use, But No Results and Virtually No Customer Support"
1/5
What do you like best about Instantly?

relatively easy to use. that's about it. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

I am almost two months in and have experienced no results from the product. I have reached out to see if I could get some support on boosting results. There is no one in this company that is willing to help customers. You have access to an AI bot and a weekly webinar. That's it.

Also, I was not impressed by the pre-sales process. My rep did a quick demo and sent a few emails back and forth. Right before I was ready to make a decision I asked the rep to setup a call to address some questions I had before making the purchase. He told me he could not make time for the call and that his focus was prioritizing new leads. Prioritizing new leads over end of the funnel sales opportunities?! Make it make sense. What a slap in the face. I am spending close to $400 a month with this company for no results and zero customer service. Not $10. Review collected by and hosted on G2.com.

"Pre-Warmed Mailboxes and Solid API That Save Weeks on Cold Campaign Launches"
4.5/5
What do you like best about Instantly?

The pre-warmed mailbox pool is the biggest unlock. We run cold campaigns for multiple clients and the ability to spin up warmed mailbox inventory in minutes, versus setting up domains, DKIM, and 2-week warmups ourselves, saves weeks per client launch. The warmup engine itself works well and the API is solid enough that we automate most of our campaign builds, lead uploads, and reply handling programmatically through it instead of clicking in the UI. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

The mailbox reconnection flow when OAuth tokens lapse could be smoother. If a Zapmail-managed mailbox subscription has a billing hiccup, the mailboxes go into errored status with no clear in-app guidance on the right recovery path. First reaction is to try CSV bulk re-import, which fails on the IMAP test because Google requires App Passwords, not login passwords. Took a couple support tickets to learn the actual fix is over on the Zapmail side via re-export. A simple inline message like 'reconnect via Zapmail' on errored Gen-2 mailboxes would save first-time users a lot of digging. Beyond that, a few API quirks (DELETE rejecting Content-Type header, /activate requiring an empty body) took some trial and error. Review collected by and hosted on G2.com.

"Easy AI Personalization and outreach"
4.5/5
What do you like best about Instantly?

I like that Instantly helps me handle my entire cold outreach work all in one place, instead of using separate tools for tasks like finding leads and verifying emails. I also appreciate features such as AI personalization and the way it manages website visitors. Overall, it has made my outreach process much easier to manage. Switching to Instantly from Lemlist made my life easier due to its price and the new features it offers, like the credit system called super search. The setup was easy for me thanks to my previous use of similar tools, and I find Instantly's approach to warming up emails and tracking replies straightforward. Also, I'd rate it nine out of ten since I don't have anything negative to say. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

You know, once you get used to it, it's fine. But in the beginning, it can feel a bit overwhelming. Apart from that, I haven't had any major issues as such. Review collected by and hosted on G2.com.

"Powerful Email Campaign Tool with Dynamic Features"
4.5/5
What do you like best about Instantly?

I find Instantly easy to use and it's straightforward to set up. The support team is attentive and provides assistance even if it takes a while, and I have found the support to be excellent when needed. Instantly gets good results and is not a platform that stands still, which is important given the rapid changes in deliverability rules. They constantly update the platform to keep it current. I also like that new features are constantly being added, which enhances its functionality and efficiency. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

The only issue I would mention is that there is a lot of bolt on pricing and push to upgrade your level and add this and that that can all add up to a greater cost. Review collected by and hosted on G2.com.

"Streamlined Outbound Sales in One Platform"
4.5/5
What do you like best about Instantly?

I really like that Instantly continues to evolve beyond just being another cold email platform. My favorite part is how everything works together in a single ecosystem. SuperSearch makes prospecting simple, and email verification helps maintain data quality. The campaign automation is intuitive and powerful, and the inbox centralizes replies from multiple inboxes, making conversations much easier to manage. I rely heavily on AI-powered features like AI personalization, AI sequence generation, and the AI spam checker to improve campaign quality without spending hours manually optimizing every email. Plus, my initial experience with Instantly was surprisingly straightforward. The interface is intuitive, so it didn't take long to get comfortable with the core workflow. The platform also integrates well with my sales and marketing tools, like Slack, CRM platforms, and Zapier, making my work seamless. Additionally, Instantly combines prospecting, email verification, campaign automation, and more into a single ecosystem, and the support team has consistently been responsive and knowledgeable. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

Overall, I've had a very positive experience with Instantly but there are still a few areas that could be improved because the platform evolves quickly and new features are released regularly. The documentation and help articles sometimes take a little time to catch up with the latest functionality. So as the platform continues to expand, beyond, you know, cold emails like super search, website visitors, instant link credits, AI features, and outbound tools, there can be a slight learning curve for new users. More guided onboarding and in-app walkthroughs for newer features would make adoption even smoother. Review collected by and hosted on G2.com.

"Effortless Email Marketing with Stellar Support ."
5/5
What do you like best about Instantly?

I love how Instantly has revolutionized my email marketing efforts. Its ability to solve the problem of sending bulk emails across different time zones is essential for global campaigns and ensures that messages reach recipients at the most optimal times. The AI reply agent is a standout feature for me; it efficiently drafts responses based on client replies, saving me valuable time by simply requiring a review before sending. Instantly's email marketing automation capabilities are outstanding, especially with features like the warmup email option, which prepares inboxes for high deliverability, and the ability to send follow-up emails on a timely basis, ensuring no lead is left untended. I also appreciate the inbox placement test that gives insights into how many emails land in the inbox versus the spam folder, which helps in fine-tuning email strategies. Additionally, the supportive and responsive customer support team has made the setup and use of Instantly a seamless experience, providing reassurance and quick solutions when i needed.

"Efficient Email Automation with Instantly"
4.5/5
What do you like best about Instantly?

I use Instantly for email automation which significantly reduces manual headaches. The best feature for me is the Email Warmups. This is automated, so I don't have to do anything but add my ID to the warmup setting, and it automatically sends and receives warmup mails to maintain email health. Additionally, I really appreciate the Dashboard analytics, which lets me find all the campaign performances in one place, and I can even review individual campaign performance. The initial setup was very guided and supportive, which means any layperson can go through it without any issues. Our team found Instantly useful and it added more value to our work compared to other options like Lemlist. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

UI such as user experience can be improved. Review collected by and hosted on G2.com.

"THE tool for scaling cold outreach"
4.5/5
What do you like best about Instantly?

In my experience, Instantly is easily the most user-friendly and effective for scaling outreach. Being able to connect as many inboxes as you need without a per-user fee is a game-changer. And the Unibox makes managing all those accounts effortless. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

Nothing much, really, maybe just the reporting part could be perfected. The analytics are good for the basics (opens, clicks, replies), but I’d love to see more granular reporting and advanced behavioral triggers for automations. Review collected by and hosted on G2.com.

"Well-Designed Outbound Emailing with Great Warmup, Fair Pricing, and Reactive Support"
4.5/5
What do you like best about Instantly?

It works, you don't have to worry about email spam quality... the system is well designed for it so if you want to run proper outbound campaigns without stressing about the emailing and tooling Instantly does it for you

1. Inbox warm strategy is the favorite part

2. lead status detection matching also works

3. Pricing is also fair tbh

i'd recommend this tool no questions asked, their support is also good and super reactive Review collected by and hosted on G2.com.

What do you dislike about Instantly?

the lead gen side is still weak unfortunately, I think the main issue is that you 'd still need 2-3 other tools with instantly even if the ycan just increase their scooe

Be aware integration isn't native with other CRMs, it's a 1 way so you'll either keep haklf the work manual or have t obuild something yourself Review collected by and hosted on G2.com.

"Easy Setup, But Pricey"
3.5/5
What do you like best about Instantly?

I like that the setup with Instantly is super easy. I appreciate how I can get the infrastructure set up very quickly, taking away a lot of the technical knowledge and hassle. Instantly kind of handles the whole process for me, allowing me to get the infrastructure set up and then be sending emails in the same day. Also, I've heard that deliverability is better on Instantly, which influenced my decision to switch from Lemlist. Review collected by and hosted on G2.com.

What do you dislike about Instantly?

The cost, I think, is quite expensive. Review collected by and hosted on G2.com.
