Usage limits

How many actions the assistant can take

To keep the service fast and safe for everyone, MailSenpai limits how many actions an AI assistant can take on your account in a short time. The limits apply to the assistant's requests, not to the number of emails you can send to your contacts.

In practice: normal use never reaches these limits. If the assistant goes too fast, MailSenpai asks it to wait a few seconds (at most a minute, an hour only for scheduling) and then it can carry on. Actions already completed stay saved.

A few examples

Weekly summary

The assistant finds your last 10 campaigns and reads their statistics: 1 view and 10 statistics reads. Well within the limits.

Preparing a campaign

It creates a template, prepares the campaign draft and schedules it: one action of each type. Scheduling always asks for your confirmation.

Cleaning up

Deleting 5 old test campaigns counts as 5 deletions. Each deletion also asks for your explicit confirmation.

Limits that depend on your plan

Some things depend on your MailSenpai plan: for example how many contacts you can import at once, how many results you see per page and whether you can send or delete. To find out what your account can do, ask the assistant: "What can I do with MailSenpai?".

What about sending emails?

These limits do not change how fast your campaigns reach your contacts: that depends on your MailSenpai plan.

Note for developers: when a limit is exceeded the server replies HTTP 429 with a Retry-After header (seconds to wait). Questions: supporto@mailsenpai.com.
