Open rates are a noisy metric since privacy changes, but a steady decline is still a real signal. The mistake is treating it as a copywriting problem when it is usually a placement or relevance problem.
First: are you even reaching the inbox?
- Seed-test placement across Gmail and Outlook with a testing tool or fresh accounts.
- Check authentication: SPF, DKIM and DMARC must pass; mainstream providers now demand it.
- Watch Google Postmaster domain reputation; a slide there explains everything.
- Spam folder placement masquerades as 'low opens' more often than any other cause.
Second: the list itself
- Unengaged subscribers accumulate and mathematically sink the rate while hurting reputation.
- Run a re-engagement campaign at 6 months of silence, then suppress non-responders.
- Kill low-quality sources: that giveaway list is poisoning the average.
Third: relevance and cadence
- Same message to everyone trains inattention; segment by interest and behaviour.
- Inconsistent sending resets attention; pick a sustainable rhythm.
- Sender name recognition beats subject cleverness; people open people.
Only then, the copy layer
With placement and list health fixed, subject lines and preview text are worth testing: specificity beats puns, curiosity beats clickbait, and the preview line is half the battle. Test one variable weekly and keep a swipe file of winners.

Frequently asked questions
What is a good email open rate in 2026?
Across industries, 25 to 40% for healthy lists, with welcome emails far higher. Trends matter more than absolutes since Apple privacy inflated baselines.
Should I delete subscribers who never open?
After a re-engagement attempt, suppress or remove them. A smaller engaged list delivers better, ranks better with mailbox providers, and usually earns more revenue.
Why did opens drop suddenly after months of stability?
Sudden cliffs point to placement: an authentication break, a reputation hit from a bad send, or a platform change. Gradual slides point to list decay and relevance.
