Lekalao prepares, personalises and follows the e-mails; a mailer hands them to the mailboxes. You keep your own account, your own prices and your own reputation with the provider you choose. Settings → Mailers.

​
Add a mailer

Add a mailer, then:

​
Mailer

A name (“SES production”) and the kind. The form then shows the fields of that kind.

​
Credentials

Stored encrypted in the database. On a mailer that already exists, a secret already saved shows as “Saved — leave empty to keep it”.
At the provider, create a key limited to sending (and to managing webhooks if you want them configured for you), never a key that administers the account.

​
Feedback

What the provider sends back: deliveries, bounces, complaints. See Provider feedback. Depending on the kind, a signing secret field appears (Mailgun, SendGrid, Resend). The Webhook URL appears once the mailer is saved.

​
Sending rate

The largest number of e-mails per period, written “N e-mails every N seconds”: 14 e-mails every 1 second for SES out of its sandbox, say. Leave it empty for no limit. Lekalao keeps to it for campaigns and automations; beyond it, e-mails wait their turn.

​
Testing

On a mailer’s page, Test the mailer: an address, then Send a test e-mail. The result appears (Working, or Test failed with the provider’s exact error; Not tested before the first attempt) and the date of the last test is kept.
A mailer that has never passed a test cannot send a campaign: the campaign says so in its summary. Test again after every change of credentials.

​
A provider per kind of sending

Below the list of mailers, Mailer per sending type: “Use the default mailer” leaves the choice to the default.
Keeping campaigns apart from transactional e-mail protects the ones that matter: a campaign that raises complaints does not spoil the reputation of the stream that sends the invoices.

​
Deleting

At the bottom of a mailer’s page, Delete the mailer. Its credentials are erased; the sending types that used it fall back to the default mailer.
