Frequently Asked Questions

Common questions about SMTP Senpai

Yes. The plugin sends email through SMTP Senpai, so you need an account and an API key or SMTP credentials. Until the plugin is configured, WordPress keeps using its default mailer.

In the MailSenpai customer area, on the SMTP Senpai page. The key starts with msp_. See the documentation.

An address on a domain verified in your SMTP Senpai account (subdomains are accepted). If WordPress or another plugin uses a different domain, the API answers with an error that the plugin shows in the log and in the test email result.

The API sends every recipient (To, Cc and Bcc together, up to 50) an individual copy, so the Cc list is not shown to the other recipients. If you need visible Cc headers, use SMTP mode.

The email fails and the error is written in the log. If you turn on the fallback option, the email is handed to the default WordPress mailer instead. Addresses on your suppression list are never retried.

Date, status, sending method, recipients, subject, message ID and error text. Message bodies and attachments are never stored. Privacy mode masks the addresses (m***@example.com) and drops the subjects. Entries are deleted automatically after 7, 14 or 30 days.

Yes. Activate it network-wide or per site: each site has its own settings, log and cleanup schedule.

No. The plugin does not collect usage data, does not load external scripts, fonts or images and does not show ads.

Yes. Go to SMTP Senpai → Settings → Display and untick "Show in the admin bar". The item is only shown to users who can manage the plugin.

Yes. The old address opens the new pages of the SMTP Senpai menu.
