Common Questions

Frequently asked questions

What is a good open rate for an author newsletter?

Author newsletters typically see 25–45% open rates, which is higher than most industries. If you're below 20%, consider list hygiene (removing inactive subscribers) or improving subject lines.

How many sales can I expect from an email campaign?

Conversion rates vary widely — a warm, engaged list might convert at 1–3% of total subscribers per campaign. A cold or disengaged list may be under 0.5%. Your track record and offer matter more than list size.

Is it worth building an email list as an indie author?

Yes — an email list is the highest-ROI marketing channel for most indie authors. Unlike social media, you own the relationship and aren't subject to algorithm changes. Even a list of 1,000 engaged readers can drive significant launch revenue.

How often should I email my author list?

Most author marketing experts recommend at least once a month to stay top of mind, with more frequent emails during launch week. Consistency matters more than frequency — a regular monthly newsletter builds better engagement than sporadic blasts.
