Email marketing has a reputation problem it doesn't deserve. People assume it's outdated because their own inbox is full of spam, but for small businesses it remains one of the highest-return channels available, mainly because you own the list — no algorithm decides whether your message gets seen.
Start with permission, not volume
The single biggest mistake I see is chasing list size instead of list quality. A purchased list of 5,000 addresses will get flagged as spam, tank your sender reputation, and land your legitimate emails in junk folders for months. A list of 200 people who genuinely signed up — because they bought something, asked a question, or wanted a discount — will open, click, and buy at rates a bought list never will.
Give people a real reason to sign up
"Subscribe to our newsletter" is not a compelling offer to anyone. A specific discount, an early-access list for a sale, a genuinely useful checklist or guide — these convert because they trade something concrete for an email address instead of asking for it out of goodwill.
What to actually send
- A welcome email immediately after signup — this alone often gets the highest open rate of any email you'll send.
- Useful, standalone content occasionally — not every email needs to sell something.
- Clear, specific promotions when you have them, sent to the whole list at once, not buried in a long newsletter.
Consistency beats cleverness
A short, plain email sent reliably every two weeks will outperform an elaborately designed newsletter sent twice a year. Momentum matters more in email than almost any other channel — an audience that hears from you regularly opens more, not less, contrary to what most people assume.
