Pay for Sendgrid (100 / day for free is not enough) VS set up your own email server?

For own email server, do you not get flagged a lot as spam ?

    Couple things that I’ve found out,

    • Gmail seems to need your server to have IPv6 with PTR, even if the mail is sent over IPv4
    • Even a DMARC record with no ruf or rua helps lower the spam score
    • For Outlook you need to send some mail to yourself or someone else and mark the messages as not spam manually for a while
    • MS365 will even put mails from Gmail to spam initially
    • Some TLDs like .xyz will go to spam even if everything is set up perfectly
    • Outlook also seems to cache DNS quite long, you may need to wait a day for changes to propagate
    • A recently registered domain will land in spam more easily, if it has been registered for a while it also seems to help

    If you’re not already familiar with these, https://mxtoolbox.com/SuperTool.aspx (write smtp:your.mx.record is a good tool, and I’ve also used https://www.mail-tester.com/. Mxtoolbox blacklist check is also good.

    I hate it that spammers have made hosting email such a hassle. Hope you get stuff running!

      I don’t have an IPv6 PTR and I send mails through a .xyz domain and everything still works at least when sending to a gmail inbox.

        Well, in that case Gmail doesn’t seem to require the PTR6 :)

        None of these are absolute, since determining spam is based on a scoring system
