Mailwarm

Mailwarm is an email warmup and deliverability monitoring tool, built by a Y Combinator (S20) team since 2020. On this channel, the Mailwarm deliverability team answers one email deliverability question per video, in under 4 minutes.

What you will learn:
- Why emails go to spam, and how to fix it
- How to set up SPF, DKIM and DMARC (Google Workspace, Microsoft 365)
- How to check if your domain or IP is on a blacklist
- How to warm up a new domain or mailbox, and Gmail and Outlook sending limits
- How to read Google Postmaster Tools, spam rate and sender reputation
- How to test inbox placement and spam score before a campaign

Every video uses real data from the Mailwarm network and our free email deliverability tools: deliverability test, spam checker, blacklist checker, SPF, DKIM and DMARC checkers and generators.
