Vatsal Shah Lemwarm is quite a popular email warm-up tool — it’s good, gets the job done, and helps improve your deliverability.
But after trying and testing the tool myself, I still can’t get over the fact that I paid $24 per inbox (monthly, Base plan) — and there’s no free plan!
You might think, “Well, for $24 a month, I’m probably getting something super powerful, right?”
You get:
- Automatic email warm-up
- Technical setup check
- Deliverability reports
- Human warm-up emails
- Warm-up network of 20K+ healthy domains
Sounds solid — until you realize there are plenty of other tools that offer the same (or more) at a lower price, and don’t treat email warm-up like a luxury add-on.
So, I did my research, shortlisted 8 Lemwarm alternatives, and personally tried and tested each one — basically, I’ve burned my pocket so you don’t have to.
I’ve reviewed each tool’s — features, pricing, pros, and cons — to help you decide if it’s worth the switch.

3. Why should I look for Lemwarm Alternatives?
There are no reviews of Lemwarm on sites like G2 or Trustpilot, so I turned to Reddit (apart from using the platform myself). I got to know two things: there is no free plan, and Lemwarm charges you based on the number of inboxes you warm up. So if you’re managing multiple inboxes or just want to test the waters before committing — Lemwarm might not be the best fit.
