Email & Deliverability
Make sure your emails actually reach the inbox, and protect your domain from being spoofed by scammers.

The email essentials
Three DNS records and a few habits that keep you out of the spam folder.
1. Set up SPF
A DNS record listing which services are allowed to send email for your domain.
2. Set up DKIM
A digital signature on your messages that proves they weren’t altered and really came from you.
3. Add a DMARC policy
Tells inboxes what to do with mail that fails SPF/DKIM, and sends you reports. Start with monitoring, then tighten it.
4. Use a real sending service
Send website and marketing email through a dedicated email service, not your web server’s built-in mail.
5. Use your own domain
you@yourbusiness.com builds trust and deliverability far better than a free Gmail or Yahoo address.
6. Keep your list clean
Remove bounces and people who never open. Sending to dead addresses hurts your sender reputation.
7. Watch for spoofing
If you start getting bounce-backs for emails you never sent, someone is forging your domain. DMARC is the fix.
8. Secure your mailboxes
Strong passwords and two-factor authentication. A compromised mailbox is how most invoice-fraud scams start.
