Your profession changes the job the newsletter has to do. Use this page as a starting point, then read the free-plan and migration evidence for the two platforms you are considering.
Consultants
Look for a clear lead magnet, a short welcome sequence, reply-friendly broadcasts, and a way to connect the list to the service you sell. A publication-style growth layer is useful only if the newsletter itself is becoming the product.
Authors
Prioritise a readable public archive, a stable subscriber export, and a paid-subscription path that you understand. Avoid moving paid readers until you can explain the payment and refund transition.
Educators
Look for segmentation, a simple sequence, a landing page for each learning promise, and a clear path to a course or workshop. Count automations and integrations, not only the free subscriber ceiling.
