Email delivery
How many B2B emails can I send per day?
There is no universally safe daily number. Your provider’s limits, mailbox history, recipient relevance, complaints, and your ability to answer all matter. A plan allowance is a maximum feature limit, not a promise that sending that amount is appropriate. Start conservatively and let observed quality guide changes.
How to approach it
- Check the limits of your actual mailbox provider.
- Set a lower operational cap for a new or unproven workflow.
- Review responses and delivery failures before increasing volume.
A workspace may allow more messages than a newly connected mailbox should send. Keep the mailbox’s limit lower while you verify setup and targeting; unused capacity is not a problem to solve by contacting poorer fits.
