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 ?

    The set up isn’t actually hard at all, if you understand the concepts. Keeping off blacklists is the hard part, as big providers often block entire IP ranges due to one bad actor.

    Edit: I meant sometimes your server gets blacklisted for something some neighboring server did

      Well I did set one up today and the mails land in the spam folder for GMX, GMail and Microsoft (@live.de), although I set up SPF, rDNS, and DKIM. I have to take a look at how to setup DMARC, beacause my domain hoster doesn’t allow free configuration of the TXT entries, you have to use templates and there isn’t one for DMARC

        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!
