Paid Email Tools
Every tool on this page is listed as paid because its own website says so: requiring payment, including tools that start with a free trial or a few free credits and then bill. The directory used to default to "freemium" whenever a page did not say; those labels were re-read from the source in September 2026, so a filter on paid now means what it says.
Use it to shortlist email tools that fit how you want to pay, then open a listing for the description, screenshots and a direct link. If a label looks wrong, the tool's maker can claim the listing and fix it.
By pricing: All · Free (3) · Freemium (14) · Paid (3)
