An email marketing best practice is a rule you can apply on the next send.
Permission is the line that separates a list from spam.
Authentication is SPF, DKIM, and DMARC before you scale volume.
For example, a honest subject plus a working unsubscribe is not optional on commercial mail.
| Move | Why it matters |
|---|---|
| Clean the list | Quiet names drag placement down |
| Measure the job | Clicks and conversions outlast the pixel |
US commercial mail still follows the FTC CAN-SPAM guide and 16 CFR 316.3. Bulk sending still has to meet Gmail's sender requirements. To contact us about this article, use the support link above.
The practices that still move results are personalization past the first name, mobile-first layout, honest subject lines, audience segments, and inbox authentication. Automation of welcome, cart, and re-engagement beats a single blast. Measure clicks, conversions, and unsubscribes, then change the next send from that data.
Use what people did, not just their name. Send from actions, swap blocks by segment, and let predicted interest pick the offer. Pair that with segmentation so the list is not one audience. First-name tokens alone read as a mail merge.
Authenticate the domain with DKIM, SPF, and DMARC, clean the list, and skip bait subjects. Gmail's sender requirements set the bulk-sender floor. CAN-SPAM still wants an honest subject and a working unsubscribe on commercial mail.
Start with the flows that fire on a real event: a welcome sequence, abandoned cart reminders, post-purchase follow-up, and re-engagement. Those run without a new brief every week. Keep birthday mail as a later add-on once the core paths work.
Watch open rate as a weak signal, then click-through, conversion, unsubscribe rate, and revenue per email. Use those numbers to change the next campaign. A/B testing is how you prove a subject or CTA change, not a hunch.
