You can automate your cold email outreach and lead generation, send automated drip campaigns and email newsletters, manage replies, and track campaign performance, all without leaving Gmail.

GMass performs highly on popular review platforms like G2 and Capterra, and it’s also widely praised in Reddit communities. The tool has an average rating of 4.8 out of 5 stars from over 1,000 reviews on G2.
Many users praise its ease of use, customer service, Gmail integration, value for money, and robust feature set for automating cold email outreach campaigns. We think it’s a solid tool, especially when used alongside LinkedIn Sales Navigator. However, if you’re not on Gmail, this tool is pretty much useless.

Reviews:
Warmer.ai has few public reviews and isn’t present on many popular software review sites. This indicates that Warmer.ai is a relatively new or undiscovered tool. Or perhaps it’s just not utilized by as many people because it simply doesn’t offer the same email automation capabilities as other tools. While we enjoyed Warmer.ai’s ease of use and ability to quickly generate personalized email content, we feel there are better, more extensive tools out there.
Pros

We haven’t found many user reviews online, which can only mean that OutreachAI’s popularity is nowhere near the levels of other tools on this list.

EngageBay performs well on Capterra (4.6 out of 5 stars) but less so on G2 (4 out of 5 stars). Like other users, we enjoyed the tool’s user-friendliness, powerful automation features, responsive support, and helpful drip campaigns.

However, we noted minor UX issues, and the sheer volume of features can cause confusion, especially to first-time users. Additionally, there are limited integrations with other tools, so EngageBay may not be suitable for larger companies.
