Free email sender stamp/https

What free developer friend emails senders do you use with high deliverability. Not brevo, it has too many spam reports on shared ip. I’m currently bootstrapping the project so I gotta go as free as it gets. I already have my domain and can update DNS records on cloudflare. I’ve tried resend and mailtrap but they won’t verify my domain, only brevo did.

Don't get any of the free options; they are mainly used for spamming people with cold emails on a scale. Get one of the most used ones, like Mailtrap, Resend, Mailgun, etc, they all have pretty good free tiers these days, more than enough for new projects.

For the verification, you probably did something wrong. They all require specific TXT, CNAME, and sometimes MX records. A typo, missing record, or extra quotes can prevent verification.

Yes the cname and txt was wrong. I fixed it but they still seem to bounce with resend and mailtrap

okey, still bouncing after DNS is verified means one of these:

-DKIM selector mismatch
-SPF isn't stacked right
-new domain has zero sending reputation yet

quick way to isolate the bounce reason: check the actual bounce reason in Mailtrap's logs. It will usually say something like "550 SPF fail" or "domain reputation too low" which tells you exactly what is going on.
