Why teams choose Stekpad over Mailwarm
Three key differences that make Stekpad the better choice for serious email senders.
AI-generated content beats templates at scale
Mailwarm sends identical template emails across its network. Spam filters from Gmail, Outlook, and Yahoo have become sophisticated enough to detect repetitive patterns. When thousands of Mailwarm users are sending the same templates, email providers identify these patterns and discount the engagement signals they generate. Stekpad takes a fundamentally different approach: every single warm-up email is generated by Llama 3.3 70B, our advanced AI model. No two emails share the same content, making it impossible for spam filters to detect warm-up patterns across your domain or across the Stekpad network. The result is more authentic engagement signals and faster reputation building.
Complete deliverability suite included
Mailwarm focuses solely on warm-up sending — connecting mailboxes and exchanging emails to build reputation. Stekpad includes a complete deliverability monitoring suite at no extra cost. Our DNS health monitor checks your SPF, DKIM, DMARC, and MX records daily and alerts you when something changes. Our blacklist scanner checks 100+ databases continuously. Our inbox placement tests verify where your emails actually land. And our 21 free deliverability tools cover everything from header analysis to spam score checking. You do not just warm up your domain — you actively monitor and protect it over time.
Start free, pay 85% less
Mailwarm's cheapest plan starts at $69 per month, which means you have to commit financially before you can even evaluate whether the tool works for your use case. Stekpad offers a permanent free plan that includes one mailbox, warm-up emails per day, and access to the community pool. No trial period, no credit card required. When you are ready to scale, our paid plans start at €9.99 per month — a fraction of what Mailwarm charges. Our Pro plan at €29 per month includes five mailboxes with seed box access and API, and our Enterprise plan at €99 per month offers 25 mailboxes with unlimited volume and team collaboration.
