Email course software, tool by tool

Last reviewed 18 September 2026

Features and pricing change, and this page does not track them. Everything below is written as what to check and where to check it, rather than as what is true of a product today. Read the date above, then answer the questions in the product itself.

Six pages about where to send a finite daily course from: five tools and the decision itself. None of them says what a product does today, because that changes weekly and a page has no way of noticing. Each one sets out what a course of this shape requires of any sending tool, then turns that into questions you can answer inside the product in an afternoon.

There are no scores here, no ticks and crosses, and no prices. A comparison table of features is written by reading marketing pages, it is stale within a quarter, and the reader has no way to tell which cells were checked and which were guessed. What survives that decay is the mechanism: a course that runs for a fixed number of days, one day at a time, from the day each reader confirmed, asks eight specific things of a sending tool, and those eight are the same this year as last. So each page states the eight, then asks them as questions with a note on where the answer usually lives.

Every page carries the date it was last reviewed and says outright that a product may have moved since. Outbound links go to a vendor home page and no further, because an origin is stable and a documentation path is not. Nothing is called good or bad, and nothing is counted: a tool built for a newsletter, or for a marketing sequence, or for publishing in the open does that job, and whether the job you are doing is that job is a fact about you rather than about the tool. The longer writing about the format, with no product named anywhere in it, is in the guides.

What a finite daily course requires of any sending tool

Eight things, and every page below asks about all eight in this order. They are properties of the format rather than features to demand: a tool that meets six of them was built for a newsletter or a marketing sequence and does that job, and the question is only whether the two it misses are two you need.

  1. A clock that starts when the reader confirms, not on a date you picked

    Five messages scheduled a day apart work once, for the people already on the list. Everybody who joins on Wednesday starts at day three of something whose beginning they never saw.

  2. One run of the course per person, however many times they arrive

    A second sign-up from an address already inside is ordinary, and where a tool treats it as a new entry the reader receives two day threes a few days apart.

  3. Confirmation on every door, including import, manual add and the API

    A list grows through more doors than the form: an import, an integration, an API call, somebody typing an address in. Confirmation on the form alone leaves the other doors open.

  4. An unsubscribe honoured everywhere, immediately, including the header one

    Somebody who leaves on Tuesday and receives mail on Wednesday reaches for the spam button rather than the link, because the link visibly did not work the first time.

  5. A decision about the day after the last day

    A course is finite, so there is always a day six. Silence, one note saying it is over, or a door into something else: the tool has a default and the default was not chosen by you.

  6. A known answer to what an edit does to the people already inside

    Some tools push a correction to everyone, including the reader who got the old day four this morning. Some hold each person to the version they entered on. Both are surprising.

  7. The option of sending from a domain you own

    A shared sending domain starts in minutes and hides your own complaint rate inside everybody else. Whether your own is possible at all is the one axis a later upgrade rarely fixes.

  8. The addresses, the consent record and the suppression list on the way out

    Every tool exports addresses. The consent wording and timestamps are harder, and the suppression list is rarely beside them: moving without it means mailing everyone who already asked you to stop.

About these pages

They name products, which the guides deliberately do not, so they live here instead of there. Nothing on them states what a product does today: every product-specific line is a question you answer inside the product, because a confident sentence about somebody else's software goes wrong without anybody noticing. The longer writing about the format is in the guides, and what this site itself does is on the home page, where it can be checked against the software.

Thinking of writing one of these?

5dayemail hosts a five-to-ten day email course: you write it once, and everyone who joins your list gets one email a day, in order, starting from the day they confirm.

Accounts are opened a few at a time rather than by signing up. Leave your address and you will be written to when the next ones open.

One message, when there is room. No course emails, no newsletter, and the address is not passed on. Ask and it is deleted; what is kept, and for how long, is in the privacy policy.
