The record

Purpose: WarmEnvelopes schedules real warm-up emails from a configured domain through the user's Resend account to recipient inboxes they control, to build sending history.
Integration: It requires a verified sending domain and a Resend API key, and each domain stores its own key.
Pacing: A scheduler runs every 30 minutes and spreads the daily target across the day; Pro lets users configure the start, increment, and maximum volume.
Templates: WarmEnvelopes says its library contains more than 1,000 independently written messages in several languages, with randomized template and sender name.
Sending log: Each send is logged with sender, template, delivery status, and any error, and the dashboard shows daily progress against the target.
No simulated engagement: The service says it sends genuine mail to user-controlled inboxes and does not use shared inbox pools, bot opens, automated replies, or spam-folder rescues.
Limits: It does not guarantee inbox placement or fix broken DNS, poor recipient lists, or spam-like content.
Domain checker: The homepage describes a free, no-sign-up checker for SPF, DKIM, DMARC, MX, and blocklist status.
Account access: Sign-in is via Google.
Privacy: The privacy policy says account data includes Google profile details and a session cookie, while configuration data includes domains, Resend API keys, ramp settings, and recipient inboxes.
Data handling: The privacy policy says WarmEnvelopes does not read users' inboxes, sell or share data for advertising, or use analytics cookies unless accepted.
Processors: The privacy policy names Vercel for hosting, Neon in the EU for the database, Stripe for payments, Google for authentication, and Google Analytics only when analytics cookies are accepted.
Support and operator: The site identifies DataOps, s.r.o. as the operator and directs users to wearedataops.cz for contact; account deletion requests can be made by contacting the operator.
Intended audience and use: The service is for warming domains the user owns or is authorized to manage, using recipient inboxes they own or whose owners consented to receive warm-up mail.
