WarmEnvelopes
WarmEnvelopes is a web service that schedules genuine warm-up emails from a configured domain through the user’s Resend account. Messages go to inboxes the user controls, or whose owners have consented, to build sending history. Setup requires a verified sending domain and a Resend API key, with a separate key stored for each domain. A scheduler runs every 30 minutes and spreads the daily target across the day. Pro users can set starting volume, daily increases, and a maximum. The library contains more than 1,000 independently written messages in several languages, varying templates and sender names. Each send records its sender, template, delivery status, and errors, while the dashboard shows daily progress. The Free plan costs 0.00 EUR and permits four emails per day per domain across up to 10 domains. Pro costs €9 a month and supports up to 1,000 daily emails. A separate checker reviews SPF, DKIM, DMARC, MX, and blocklist status.
