Automatic recharge (auto top-up) keeps your account funded so high-volume sending never stops for lack of credits. It is mainly designed for API and SMTP integrations, where running out of credits would interrupt automated traffic mid-flight.
How it works
You set two values in My Account: the trigger threshold (when current credits drop below this number) and the recharge amount (how many credits to add). Example: if the account has fewer than 100 credits, top up by 2,000. The card on file is charged automatically each time the trigger fires.
Setup checklist
- Save a valid credit card on file
- Choose a trigger threshold low enough to avoid sending interruptions
- Choose a recharge amount that matches your normal traffic for a few days
- Receive an email confirmation each time a recharge runs
What happens if the card fails
If the card is declined, the recharge fails and we notify you. The account does not auto-charge again until a successful payment is recorded — see our payment declined guide for the resolution steps. SMTP and API may pause sends until credits return.
Refund and 12-month rule
Auto top-up credits are non-refundable, except where applicable consumer law requires otherwise. They follow the same 12-month login rule as other prepaid credits: log in at least once a year to keep them valid. After 12 months without activity, the account becomes inactive and unused credits may be deleted along with account data — see data retention.
Turn auto top-up off
Disable the option in My Account at any time. Credits already added remain available subject to the rules above. Future top-ups stop with no further charge to your card.
Pair auto top-up with the right plan
For predictable monthly volume, a subscription plan may be cheaper. Use auto top-up for spiky API/SMTP traffic that needs a safety buffer.
