Features and pricing change. Every fact stated about a product here is dated and sourced from the vendor’s own pages; what a vendor does not publish is written as a question to answer in the product itself.

Five pages, one per tool people most often try to run a finite daily course on. Each opens with the setup steps, every one linked to the vendor’s own help or pricing page, then a facts table with the date and a source for every cell, then what a course of this shape asks of any sending tool and how to check it inside the product in an afternoon.

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. Prices and plan names are not, so every fact on these pages carries the date it was checked and the vendor page it came from. Where a vendor does not publish something, the page says so rather than guessing.

These pages are written by the people who make 5dayemail, itself a tool a course can be sent from, and each one says in a sentence where 5dayemail differs. A tool built for a newsletter, a marketing sequence or publishing in the open does that job well; whether the job you are doing is that job is a fact about you rather than about the tool. The side-by-side version is the guide to email course software.

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

Each page states what the vendor publishes, dated and linked cell by cell, and turns everything a vendor does not publish into a question you answer inside the product. 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.
