Why teams choose Stekpad over Woodpecker for warm-up
Three key differences that make Stekpad the better choice for serious email deliverability.
Warm-up built from the ground up
Woodpecker added warm-up as a feature to their cold email platform. Stekpad was built specifically for email warm-up, with AI content generation, adaptive ramp-up, and comprehensive monitoring. When warm-up is a core product rather than an add-on, every design decision prioritizes deliverability outcomes. This means smarter pacing algorithms, deeper monitoring integrations, and faster iteration on warm-up quality — none of which are priorities for a platform where warm-up is secondary to cold email sequencing.
AI-powered content, not recycled templates
Woodpecker's warm-up uses standard template emails that follow predictable patterns. Modern spam filters at Gmail, Outlook, and Yahoo have grown sophisticated enough to recognize these patterns across users on the same platform, discounting the engagement signals they generate. Stekpad generates unique content with Llama 3.3 70B for every single warm-up email. No two messages share the same body, subject, or phrasing — making it impossible for filters to detect coordinated warm-up behavior. The result is authentic engagement signals that build sender reputation faster and more sustainably.
Deliverability monitoring included
Woodpecker focuses on sending — campaigns, sequences, and follow-ups. Stekpad monitors your DNS records, blacklist status, and inbox placement proactively, catching problems before they hurt your campaigns. Our DNS health monitor checks SPF, DKIM, DMARC, and MX records daily. Our blacklist scanner queries 100+ databases continuously. Combined with placement tests and a composite health score, you get a complete picture of your deliverability — not just warm-up activity. This is especially valuable when you use Woodpecker for outreach and Stekpad to protect and maintain the domain reputation that makes your campaigns land in the inbox.

Our free plan includes one mailbox and warm-up emails per day with community pool access, no credit card required. Our Starter plan at 9.99 euros per month adds a second mailbox and 20 emails per day. Our Pro plan at 29 euros per month includes five mailboxes, 40 emails per day per mailbox, seed box access, and API access.
