Email Deliverability: Landing in the Inbox
Authentication, list hygiene, and sending habits that keep your email out of the spam folder.
By Sara KhanJune 20, 20256 min read
An email that lands in spam might as well not have been sent. Deliverability is earned through trust signals, not luck.
Authenticate your domain
SPF, DKIM, and DMARC tell mailbox providers your mail is legitimately yours. Without them, you're starting in the penalty box.
Keep your list clean
Sending to dead addresses and unengaged contacts tanks your reputation. Prune regularly and let inactive subscribers go.
Send to engagement
Providers watch whether people open and reply. Prioritize your engaged audience and warm new domains gradually.
