KaiMail's new HTTP Sending API lets you send email from your custom domain over HTTPS. Same pipeline as SMTP port 587, but without needing an SMTP library. Works from serverless functions, blocked networks, and anywhere JSON over HTTPS is easier.
What a custom domain email actually is, why a free email address is no longer enough, and the exact steps to send and receive email using your own domain. From domain registration to MX records, SPF, DKIM, and DMARC.
KaiMail now supports mailing lists on your own custom domain — public forwarding lists, broadcast newsletters, and member-only discussion lists, all with proper DKIM signing and DMARC alignment. No separate tool required.
Finding reliable Email Forwarding Services prevents your custom domain email from landing in spam. See how KaiMail, Forward Email, and ImprovMX differ on webhooks, privacy, and pricing.
Sending a Custom Domain Email shouldn't be a struggle. KaiMail now supports full SMTP sending, allowing you to reply to clients professionally without clunky workarounds. Stop using your personal address for business and simplify your setup.
