No spam. One email when your invite is ready.
Gmail, Outlook, iCloud and any IMAP account in a single view. Read, search and reply in one place instead of five.
Send and receive from you@yourdomain.com. Point the domain at MailNail and everything that keeps your mail out of spam folders is set up for you.
Replies go out from the address the mail came in on, so you never answer a client from your personal account by accident. Switch address per message when you want to.
MailNail reads your mail. That is the only way the search, the sorting and the agents work at all. What it learns is yours: no ads, no profiling, nobody else's model trained on your inbox.
Look for a thread the way you actually remember it. Half a subject line, the wrong month, a name you're not sure about, and it still comes up.
Connect an account and its past arrives too, as far back as you want. You can search a thread from two years ago on the day you sign up.
Claude and your own tools plug straight in. You pick what they're allowed to touch, one mailbox at a time, and you can read back every move they made.
Half the thread landed on Gmail, half on your own domain. You still read it as one conversation.
Read it, file it or bin it in MailNail and Gmail agrees. So does the mail app on your phone. Nothing to tidy up twice.
Invite your teammates and hand them support@, billing@ or hello@. Everyone works the same inbox, sees the same replies, and answers as the address instead of as themselves.
Anyone who owns more than one address or domain. Most clients treat a single inbox as the default; MailNail assumes you have several.
