Instantly Helps Automate Your B2B Email Outreach Forever.
Also listed in Email Deliverability, AI Sales Assistant, Account Data Management, Lead Mining, Lead Intelligence

Cold email campaigns can fail before anyone even reads the first message. Sometimes the issue isn’t the copy, the offer, or the subject line; it’s poorly prepared domains, messy lead lists, missing data, or automations that aren’t connected to the rest of the workflow. That’s where Instantly has been useful for me. It doesn’t treat cold email as a separate task. Instead, it pulls sending accounts, warmup, leads, campaigns, replies, CRM activity, and automations into a single flow that’s much easier to manage. Having multiple accounts, warmup, and inbox rotation also helps a lot when you want to scale without putting all the pressure on one inbox. From a developer’s perspective, that matters because we often end up supporting domains, DNS, tracking, integrations, and the events marketing needs so the campaign isn’t just about sending more emails and hoping for the best. Instantly makes that whole operation clearer and more visible. Review collected by and hosted on G2.com.
Whether you’re looking to reach more customers, sell more products, or simply share your passion with the world, Constant Contact has all the tools, features, and expert guida
Also listed in SMS Marketing, Event Marketing, Email Template Builder, AI Writing Assistant, Email Deliverability

What I like best about Constant Contact is that it handles the core email marketing work pretty well without making everything feel like a big project. Building campaigns, managing lists, using templates, and getting emails out the door are all straightforward enough that non-technical users can usually work in it without needing IT to sit beside them the whole time.
It’s also reasonably priced for what it is, especially compared with some platforms that start simple and then get expensive the second you need normal business features. Constant Contact also offers prepay savings, including nonprofit discounts, which is helpful for organizations that have to be careful with their budget.
The support side is another plus. I like that phone support is still available, because many SaaS tools have pushed everyone into chatbots, forums, or help articles. Constant Contact isn’t perfect, but when there’s an account, billing, or campaign issue, being able to talk to an actual person makes cleanup a lot easier. Review collected by and hosted on G2.com.

What I like best about Intuit Mailchimp Email Marketing is that it makes email campaigns approachable, even if you are not a marketing expert. The platform is easy to use, has clean templates, and allows us to create professional-looking emails without needing a designer or developer.

Also listed in Calendar, Account Data Management, Sales Performance Management, Visitor Identification, Email Deliverability
Very very little. I chose Apollo primarily for its extensive B2B contact database and API capabilities. In theory, the data coverage looked strong for sales prospecting and automation workflows but the results were not even close to what I expected.
However, I never got the chance to fully experience any real benefits. I purchased a subscription that included monthly API credits, but near the end (not at the end) of my billing cycle I still had ~1,360 credits remaining when the API started returning billing errors. I was locked out before I could meaningfully use the service for any prospecting or data enrichment tasks.
The only “positive” is that their platform appears polished on the surface — until hallucination and billing issues hit. Review collected by and hosted on G2.com.

Also listed in Lead Intelligence, CRM, AI Sales Assistant, Sales Engagement, Account Data Management

The Lead Explorer is one of the most practical parts of the platform for our team. I can type what I'm looking for in plain English and it surfaces a relevant list instantly. The filter panel is also very detailed: company size, revenue, industry, job title, seniority, tech stack, and intent topics all in one view. Stacking multiple filters to narrow down a list doesn't slow anything down. The results are specific enough that we rarely need to clean the list before working it.

Dotdigital has a great and intuitive platform that I've been using for many years. It has grown and evolved over time, with new features, but continues to be very user friendly. I love how the platform can integrate easily with our website, allowing data to flow in making for smart segmentation and automation. We've seen great ROI on our abandoned basket emails, delivering great engagement and conversion rates. The support teams behind the platform have also been exceptional. We've been put on a plan that has helped us scale the usage as we've scaled in incremental fashion, rather than spilling over and having to pay for a bigger plan than is required at that time. The AI tools inside the platform via WinstonAI has been extremely helpful too, making great suggestions to subject lines and content which has improved open rate and engagement.
