MailerLite: posting rules and settings
What a MailerLite channel accepts in Postemi: media, limits, required fields, and the fields of the settings object for the API.
New in Postemi and not yet tested with many accounts. MailerLite accepts e-mails from apps only on its Advanced plan.
Basics
mailerliteRules
- You connect with an API token, a sender name and a sender e-mail verified in MailerLite.
- MailerLite accepts e-mails from apps only on its Advanced plan. On other plans the post fails with a message saying so.
- At the scheduled time Postemi creates a campaign and sends it at once. The subject is the subject setting, or else the first line of the text.
- Beta: not yet tested with many accounts.
Settings fields
These fields go into the post's settings object, alongside the __type field. In the UI, you fill in the same ones in the channel's settings section.
| Field | Type | Required | What it does |
|---|---|---|---|
| subject | string | no | Up to 255 characters. Empty: the first line of the post. |
| group | string (id) | no | A subscriber group (the groups function lists them). Empty: MailerLite's default audience. |
Examples
Each example is one item in the POST /public/v1/posts request's posts array. The envelope around it is always this:
{
"type": "schedule",
"date": "2026-09-15T09:00:00.000Z",
"shortLink": false,
"posts": [ /* the item below */ ]
}{
"integration": { "id": "<channel-id>" },
"value": [{ "content": "<p>The text of the post.</p>", "image": [] }],
"settings": { "__type": "mailerlite" }
}The channel ID comes from the channel list, and the path values for images and videos from media upload. The exact schema for the connected account comes from the settings schema endpoint. From the command line, the same thing is the --settings flag. See the CLI examples.
