What the model leaves out

Free is 100 emails a day (≈3,000/month). Bundle prices and overage rates come from the page's volume calculator. Scale 100k ($90, $1.10 per 1,000 extra) is omitted — same volume and overage as Foundation 100k at a higher price, with more features (SAML SSO, longer retention, 5,000 validations). Above 2.5M/month is Enterprise (request a quote). Foundation and Scale start with a one-month free trial.

Before you commit

Free is capped at 100 emails a day and 1 user; unlimited users start at Foundation.
Overage is billed at the start of the next month, and closing the account charges any remaining balance first.
One dedicated IP comes with Foundation 100k and Scale; extra IPs are $59 per IP per month.
