Good for Price, "Bad-ish" on SpamAssasin
I ran a test on mail-tester.com on an otherwise PERFECT domain!
here's the problem:
-1.999 URI_TRY_3LD "Try it" URI, suspicious hostname
meaning; whenever you have a LINK in your emails, it uses a 'sendfox . com. ' link which HURTS your score;
other than that, its fantastic!

Apr 13, 2026Thanks for the detailed SpamAssassin analysis. We take deliverability seriously, and our domain and IP tracking via Google Postmaster Tools shows that sendfoxmail.com (our sending domain) is ranked High.
It's possible that there are some other, lesser-used blacklist providers that mark SendFox — and all newsletter providers — as risky, but for deliverability that actually matters (Google), the data shows we're best-in-class.
Additionally, you can set up your own domain in settings to use a custom domain for your sending.
