On the SMTP Test plan, you can add 1 authenticated domain. Once you authenticate your domain and add a sender email address on it, SendPulse automatically moves your account to the free plan. If you've already purchased a paid plan, your account moves to it instead.
Email and SMTP share one list of authenticated domains. If your Email and SMTP plans have different limits, the higher limit applies.
The number of emails is calculated based on the size of the message.
| Paid plans (monthly payment and pay-as-you-go) |
An email sized at 1 MB counts as one email. An email sized between 1 MB and 25 MB counts as two emails. Emails larger than 25 MB will not be sent. |
| Free plan |
An email sized at 1 MB counts as one email. Emails larger than 1 MB will not be sent. |
The history of emails sent via SMTP during the last year is stored in your SendPulse account.
