Buy SMTP Access With Your Credit Card

Card payments clear at checkout, so the plan is live before you get back to your editor. Visa, Mastercard, and American Express are accepted, renewed monthly, with an invoice you can hand straight to accounting.

Maileroo Metrics
Card billing sits on the same platform that moves millions of messages a day, so upgrading a tier never interrupts sending.

Why Teams Pay by Card

Cards suit teams that would rather not wait on a finance approval loop. The charge clears, the quota lifts, and the paperwork is waiting in the dashboard afterwards.

Instant Activation

Your sending quota lifts the moment the charge clears. There is no approval queue to sit in and no window where transactional mail is stuck on free tier limits.

Renews on Its Own

Cards renew on the same date each month, so a missed invoice never suspends password resets or order confirmations while your team is asleep.

Details Never Touch Us

Our payment processor tokenises the card, which means the number is not stored on Maileroo infrastructure. 3D Secure runs whenever your bank asks for it.

Invoices You Can File

Every charge produces a dated invoice carrying your company name, address, and tax number, ready for expense claims and quarterly reconciliation.

Move Tiers Freely

Volume changes, so plans should too. Step up before a campaign and back down afterwards without touching credentials, domains, or API keys.

No Contract to Sign

Billing runs month to month with no minimum term. Cancel from the dashboard and the card is not charged again at the next renewal date.

Checkout

Four Steps to a Paid SMTP Account

Nothing here needs a sales call. Most people go from signup to a paid tier in the time it takes to find their wallet.

Step 01
Create Your Account
Sign up with an email address and verify it. The free tier covers 3,000 emails a month while you test the integration.
Step 02
Pick a Volume Tier
Choose the monthly send volume you need. Every paid tier carries unlimited sending domains and the same feature set.
Step 03
Enter Card Details
Add a Visa, Mastercard, or American Express card at checkout, then confirm 3D Secure if your bank prompts you for it.
Step 04
Send Straight Away
The new quota applies at once. Your existing SMTP credentials keep working, so the next message goes out on the paid plan.

FAQ

Card Payment Questions

What we get asked about card billing: accepted networks, renewal dates, invoices, and what happens when a charge is declined.

Visa, Mastercard, and American Express are all accepted, including debit cards issued on those networks. If your bank applies 3D Secure, the extra confirmation step appears during checkout and takes a few seconds.

No. Card details are tokenised by our PCI DSS compliant payment processor, so the raw number never reaches our servers. We keep the last four digits and the expiry date so you can tell two saved cards apart.

The first charge happens at checkout and the quota applies immediately. After that, the same date each month is used for renewal, so a plan bought on the 12th renews on the 12th.

Every plan is priced and charged in US dollars. If your card is denominated in another currency, your bank handles the conversion and may add its own foreign transaction fee.

Yes. Each payment produces a dated invoice in the billing section of your dashboard, and you can add a company name, address, and tax number that appear on every future invoice.

We email you and retry the charge. Update the card from the billing page and the retry clears, which avoids the plan lapsing back to the free tier at the end of the paid period.

Yes. Move up or down a tier whenever your volume changes. Your SMTP credentials, sending domains, and API keys stay exactly as they are, so nothing in your application needs editing.

PayPal and cryptocurrency are both available if a card is not convenient. All three methods buy the same plans at the same prices, and you can switch between them from one invoice to the next.
