Write, test, send at everyone’s own nine o’clock

Test the subject, the content, or both, on a sample. Choose what decides (opens, clicks or revenue) and how long to wait. The winner goes out to the rest of the list without anyone coming back to press a button.

An hour you choose is delivered in the subscriber’s own time zone, or the list’s when theirs is unknown. A campaign spreads over the time you say. A list can refuse sends outside its hours, even across midnight.

Every night Lekalao learns, from six months of opens by people — never by a machine fetching images — the hour each subscriber reads their e-mail. Tick one box and each e-mail leaves the next time that hour comes round. Whoever has no hour yet leaves with the others; nobody waits more than a day.

A subject in capitals, a fake “Re:”, a link shortener, a link that shows one address and leads to another: said before the send, not after. A link whose words are an address is never sent through click tracking — that is what phishing looks like. And on an installation that runs rspamd, a real filter gives its score.

A campaign leaves only once a member other than the one who asked has approved it. The approval is of this very campaign: change a word, the list or the sender, and it is looked at again. And writing is not sending: a Writer prepares, an Editor sends.

Every send is recorded before it leaves. A server restarts, a queue retries: nobody receives the same e-mail twice, and stuck sends resume on their own.

Give it an RSS or Atom feed. Lekalao writes to the list when there is something new: at once, every day or every week. An article already sent never goes out again.
