Are Email Blasts Still A Viable Marketing Strategy?

Email blasts are still a viable way to reach people who already know you. They are a bad way to introduce yourself to strangers. The inbox rules that tightened in 2024 are still the rules in 2026. Authenticate the domain, make unsubscribing obvious, and keep complaint rates low. A blast that ignores those does not get a second chance. It teaches Gmail and Yahoo to distrust the domain.

Used properly, one email about a real change, a finished season, or an offer your customers already buy will outperform another month of social posts that your followers never see.

When a blast is the right tool

• The list opted in. Past customers and quote requests count. A list you bought does not.
• The message is about one action, such as booking before the season, claiming a maintenance slot, or reading a change in pricing.
• You can say who it is from in the first line without a gimmick.
• People who are not interested can leave in one click.

When it is just spam with your logo

A monthly newsletter with no ask, sent so the calendar stays full, trains people to ignore you. So does a “blast” to every address that ever touched a form, including vendors and job applicants. Segment at least into customers and people who have not bought. If you cannot, you are not ready to send.

The rules that decide whether it arrives

Publish SPF, DKIM, and a DMARC record that matches how you send. Use a consistent From name. Align the visible domain with the authenticated domain. Bulk senders are expected to offer a one-click unsubscribe and to keep spam complaints under about 0.3%. Those are mailbox-provider requirements, not optional best practices. The setup steps live in how to improve email deliverability.

What to measure instead of open rate

Open rate has been a soft number since Apple started prefetching images. Watch clicks on the real action, replies, unsubscribes, and complaints. A high open rate with no clicks is a subject line that overpromised. A spike in complaints means the list or the frequency is wrong. Stop and fix that before the next send.

Send less often, to people who asked, about something they can do this week. That is the whole case for keeping email blasts in the mix.
