Business email that does not bounce into the void

Customers still write to an address. If that address is a Gmail with your trade name in the display field, you look temporary.

The three records

• SPF lists who may send. Keep it short. Do not stack ten includes.
• DKIM proves the message was not edited in transit. Rotate keys when a vendor changes.
• DMARC tells receivers what to do with failures. Start at p=none, read the reports, then move to quarantine and reject.

Routing vs. mailbox

Cloudflare Email Routing can catch info@ and drop it in the inbox you already live in. That is a fine year-one setup. When two people need history, move to a real mailbox. Do not forward in a loop.

HTML mail is a product surface

If you send campaigns, send HTML that degrades to a readable plain-text part. Dark themes exist. Giant images do not survive Outlook. This is why RegisterMySite keeps an HTML email generator next to the site generator.

Signatures

One logo, one phone, one address. No stack of social icons that 404. The best signature is short enough that a reply still fits on a phone.
