Need more sending capacity? You can add extra mailboxes to your existing plan at any time. There are two steps: buy the add-on, then create the new mailboxes.
Note: New Google Workspace mailbox purchases are currently paused — the add-on flow below is for SMTP mailboxes. If you already have unused Google Workspace slots on your plan, you can still create mailboxes with them in step 2. Support for your existing Google Workspace mailboxes (creating, deleting, connecting to sequencers, etc.) is unaffected.
1. Buy more mailboxes
In your dashboard, go to Billing → Packages & Add-ons.
Choose how many SMTP mailboxes you want to add.
Complete checkout. Your new mailbox allowance is added to your account right away.
2. Create your new mailboxes
Go to Accounts → Add more email accounts.
Pick the mailbox type. SMTP is available to purchase now; Google Workspace can only be selected if you already have unused Google Workspace slots on your plan. Note that a single domain is used for one type only — either Google Workspace or SMTP, not both.
Enter the sender names and usernames for each mailbox, then choose the domain they should sit on.
Wait for the mailboxes to show as Active. This usually takes about 30 to 90 minutes.
If you need a custom number of mailboxes
Add-ons are sold in set bundle sizes (for example, a minimum of 10 at a time), so the dashboard may not let you buy an exact custom amount on its own. If you need a specific number of SMTP mailboxes, just contact us with your account email and the exact quantity you'd like, and we'll add that allowance to your account for you.
Adding more domains
If you also need more domains, you can purchase them from your dashboard the same way you did when you first set up your account. If you're not sure how many domains your new mailboxes need, contact us and we'll help you plan the right setup.
