AI that sounds like you, not a robot
Most AI copy reads like a marketing department wrote it. AuthorSend's assistant is tuned around what actually works for author newsletters — it drafts subject lines and body copy in your voice, scores the variants, and lets you rewrite until it sounds like a letter to your readers.

Teach it your voice once, hear it everywhere
Build a brand voice profile from tone descriptors, vocabulary preferences, phrases to avoid, and example snippets of your real writing. Every generation — subject lines, body drafts, rewrites — is filtered through that profile, so the output reads like you on a good writing day.
- Tone descriptors and vocabulary preferences shape every draft
- Banned phrases stay banned — “limited time” never sneaks in
- Example snippets from your own emails anchor the style

The same voice-aware AI shows up wherever the work happens — and it's included on every plan.
Scored subject lines
Generate multiple subject line variants, each scored, so you pick with evidence instead of gut feel.
Body drafts in your voice
Full body copy generation that pulls from your brand voice profile — a starting draft, not a soulless template.
Rewrite & tone control
Highlight what you have and refine it — warmer, tighter, more excited — without losing what makes it yours.
Optimal send-time prediction
The assistant predicts when your list is most likely to open, so your email lands at the right moment.
Segments from plain English
Describe who should get the email and the AI assembles the targeting rules for you to review.
On every plan
A generous monthly quota of AI generations is included on every plan — it resets each month, no add-on required.
I used to stare at the subject line box longer than I spent writing the email. Now I generate five options, pick the highest score, and they still sound like me — my readers haven't noticed a thing, except that I email more often.
