AWS SES costs are separate and billed directly by Amazon. AWS SES charges $0.10 per 1,000 emails. A typical 10,000-subscriber monthly newsletter costs about $1 in AWS fees on top of the SES Mailbox subscription.

Upgrading to Pro

To upgrade:

Go to Settings → Billing → Upgrade to Pro
Click Upgrade — $9.99/mo
You'll be redirected to PayPal to authorise the recurring subscription
After approval, you're redirected back to SES Mailbox and your plan upgrades instantly

Pro features are available immediately after PayPal confirms the subscription. If you experience a delay, refresh the page or contact support.

Billing cycle

The Pro plan is billed monthly on the same date each month (the date you first subscribed). For example, if you subscribe on May 10th, your next charge is June 10th.

Payments are processed by PayPal. You receive a payment confirmation email from PayPal for each charge. SES Mailbox does not store your payment method — all payment data stays within PayPal.

Cancelling or downgrading

You can cancel at any time:

Go to Settings → Billing → Manage subscription
Click Cancel subscription
Confirm the cancellation

After cancellation, you retain Pro access until the end of the current billing period. After that, your account automatically reverts to the Free plan. You do not lose any contacts, campaigns, or settings when downgrading — you're simply limited to 1 campaign per month again.

Cancelling in SES Mailbox is separate from cancelling in PayPal. Always cancel via the SES Mailbox settings page, not directly in your PayPal account. Cancelling only in PayPal may leave your SES Mailbox subscription in an unexpected state.

Refund policy

We offer a 14-day money-back guarantee on your first Pro payment. If you're not satisfied, email support@sesmailbox.com within 14 days of your first charge and we'll issue a full refund via PayPal.

Subsequent monthly payments are non-refundable. We do not issue partial refunds for unused time within a billing period.

Invoices

PayPal sends a payment receipt to your PayPal email address for each charge. For a formal invoice with your company details, contact support@sesmailbox.com and we'll generate one for you.

Team member access

Pro plan accounts can invite additional team members to access the dashboard. Team members can create and send campaigns but cannot access billing settings or API keys (owner only). To invite a team member: Settings → Team → Invite member.
