Nest 'all' and 'any' groups as deep as your logic goes

Most platforms stop at one flat list of conditions. AuthorSend lets you nest AND/OR groups arbitrarily deep — readers tagged fantasy who opened in the last 90 days, AND who either clicked your launch campaign or carry a 4+ engagement rating. If you can say it, you can build it.

  • 32+ attributes: lists, tags, engagement rating, signup date, email and name fields, custom fields, campaign activity, opens and clicks within date windows
  • 16+ operators, from equals/between to contains, before/after, in last N days, and opened/clicked (or not)
  • A live match-count preview shows exactly how many readers qualify before you send

AI segments

Or just describe the audience in plain English

Type something like 'readers who joined from my prequel magnet but haven't opened anything in two months' and the AI assistant translates it into a proper nested segment — conditions, operators, groups and all. Review it, tweak it, save it.

  • Natural-language descriptions become editable segment logic, never a black box
  • Generated segments use the same builder, so you can refine every rule by hand
  • Save the result and reuse it across campaigns and sends

Scored against engagement data from author newsletters — included on every plan.

Built for working authors

Targeting tools that do the bookkeeping for you

Engagement ratings

Every reader carries a 1–5 engagement rating that updates automatically — segment on it like any other field.

Saved segments

Build a segment once and reuse it for every campaign. Edit it in one place and every send picks up the change.

Pre-built templates

Start from ready-made segments like “engaged readers” or “launch-ready list” instead of a blank canvas.

Campaign-activity targeting

Target readers by what they did with past sends — opened, not opened, clicked, or not clicked, within any date window.

Custom fields

Segment on anything you track — favorite series, reader source, store preference — alongside built-in fields.

Date-window precision

Before, after, between, or in the last N days — signup dates and activity windows down to the day.

My launch email used to go to everyone and convert nobody. Now I send it to readers who clicked the cover reveal but haven't preordered — and the live count tells me who I'm reaching before I press send.
