Effortless Inbox Success with Warmforge **Rating:** 5.0/5.0 stars **Reviewed by:** Dave W. | Founder & Fractional Revenue Development Lead, Small-Business (50 or fewer emp.) **Reviewed Date:** June 20, 2026 **What do you like best about Warmforge?** I really appreciate Warmforge for warming up my mailboxes, which helps keep them with a high rating for landing in inboxes on email campaigns. It's a great tool that saves me time from having to do the warming on my own, and I find it valuable that it's a free service with a Salesforge plan. I love how it's unlimited and so easy to use, along with its very clean dashboard, daily tracking, and how it's organized well. The integration is also seamless with all of the email sending 'Forge' stack, making my workflow smoother. I can easily see how many daily emails are being sent from each and track what the score is. The initial setup was easier than Smartleads, and I'm very happy with the change. **What do you dislike about Warmforge?** When I make changes to the signature in the Warmforge tool, it's not very 'sticky.' I had to add the signatures multiple times before they stuck. **What problems is Warmforge solving and how is that benefiting you?** I use Warmforge to ensure my email campaigns land in inboxes consistently. It saves me time by warming mailboxes and provides a clean dashboard for tracking. Its integration with my email stack is seamless and it keeps my mailboxes with a high rating. ### 2. Warmforge helps improve email deliverability with warmup and inbox placement tests **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** May 21, 2026 **What do you like best about Warmforge?** Warmforge is useful because it helps us manage email warmup, sender health, and inbox placement in one place. The aged warmup pool is one of the best parts because it helps mailboxes build a better sending history before we use them for outbound. The inbox placement test is also very useful because we can see whether emails are landing in Primary, Promotions, or Spam before launching campaigns. The UI is simple enough to check mailbox health without spending too much time. Support and onboarding have also been helpful when setting up mailboxes and understanding what needs attention. Overall, Warmforge.ai gives us more confidence before sending cold email campaigns. **What do you dislike about Warmforge?** You still need to understand the basics of email deliverability to get the best results **What problems is Warmforge solving and how is that benefiting you?** Warmforge helps us reduce the risk of emails landing in spam.

Warmforge Keeps Cold Emails Landing in Primary **Rating:** 5.0/5.0 stars **Reviewed by:** Jessica K. | Outreach Specialist, Small-Business (50 or fewer emp.) **Reviewed Date:** June 17, 2026 **What do you like best about Warmforge?** One thing I liked the most about Warmforge is how it protects sender reputation on autopilot. One click warms up your mailboxes, tracks your heat score, and runs placement tests, so your cold emails land in primary, not spam folder. **What do you dislike about Warmforge?** The only downside is that you can't really test it before paying; there's no free trial on the warm-up slots. A short trial would make it much easier to commit with confidence, but the prices are pretty reasonable, and I didn't regret it after buying one. **What problems is Warmforge solving and how is that benefiting you?** Cold email deliverability is a constant battle. Warmforge takes that stress away. My emails consistently land in the primary inbox, sender reputation stays protected, and I spend zero time worrying about DNS issues or blacklists. More emails delivered mean more replies, more meetings, and more pipeline. ### 4. Flexible Email Warm-Up with Seamless Salesforge Connection **Rating:** 5.0/5.0 stars **Reviewed by:** ANTON S. | Collaboration Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** February 27, 2026 **What do you like best about Warmforge?** It connects automatically if you have Salesforge. The warm-up settings are flexible: you can control how many emails to send, the timing, etc. There is a warm-meter that helps estimate if your mailbox is ready for a real operation. You can also set up a filter so your inbox doesn't turn into a 'trash bin' once the warming process starts. The design and everything else are on the same level as the rest of the *forge infrastructure. **What do you dislike about Warmforge?** No complaints—it's just a good, useful tool. Probably the only downside is the thought of how much energy is being consumed globally by these kinds of warm-up processes. **What problems is Warmforge solving and how is that benefiting you?** I'm using this useful feature to warm up mailboxes for mass outreach. Without it, all emails would go straight to spam, and the mailboxes would end up on a blacklist. ### 5.

Currently I have 71 mailboxes being warmed up and it took me a few seconds to upload them. **What do you dislike about Warmforge?** In the beginning it takes a while to understand all their apps and how they interact with each other. Warmup only starts a few hours after all is set. **What problems is Warmforge solving and how is that benefiting you?** cold mail became an art and requires deep knowledge.

This realistic approach is key to staying out of spam folders and building a sustainable, long-term reputation with email providers.

The Heat Score dashboard makes it easy to track progress, and multi-inbox management is a big time saver. **What do you dislike about Warmforge?** Setup requires DNS/SPF/DKIM knowledge, so non-technical users might struggle.
