My list would be: Reputable hosting company, or BYOIP Reputable domain and TLD. FCrDNS SPF DKIM > 1024b and rotated regularly. DMARC as either reject or quarantine. Making sure your system doesn't backscatter. Sign up at dnswl.org I've done those things at least every other year with various domains (both testing and in-use) and never had trouble sending. Yes, there have (and will always be) the big mailbox providers who see a new IP/domain and stuff it in bulk/spam folder, but after the receiver clicks "this is not spam" most of the time there are no future problems. And, if there ever was, the folks here on mailop are overwhelmingly glad to help. There's no secret sauce to deliverability, it's just common sense stuff. It's not easy, but it's not hard. -Jim P. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
