Business inboxes
Business inboxes are included with every plan.
Start at $29/month with up to five provisioned business email addresses. We apply no markup to the included allowance at launch. Additional inboxes cost extra. You can also connect supported Google Workspace and Microsoft 365 inboxes you already own.

Two setup paths
Use the mailbox infrastructure that fits your operation.
Connect Google Workspace or Microsoft 365
Authorize mailbox synchronization through OAuth, then pass an independent SMTP connection test before the inbox becomes eligible to send. OAuth does not replace the SMTP sending credential.
Provision configured business inboxes
Create business email addresses after your domain and nameservers are ready. Your plan includes the listed allowance with no markup at launch. Additional inboxes cost extra.
From mailbox to campaign
Provisioning is the start of a controlled sending workflow.
Choose an owned domain
Use a business domain you control and complete its DNS setup before purchased mailbox provisioning.
Connect or purchase
Authorize Google or Microsoft mailbox synchronization and verify SMTP sending, or purchase a configured mailbox through the in-product reseller flow.
Warm progressively
Ramp activity instead of treating a newly connected mailbox as immediately ready for full campaign volume.
Set sending limits
Use conservative per-inbox limits that reflect mailbox age, provider guidance, and domain health.
Add to a sending pool
Distribute campaign work across eligible inboxes. This keeps volume from collecting in one account.
Monitor replies and health
Keep reply handling, bounce signals, warmup, and inbox health visible in the same workspace.
Capacity and cost
Your plan includes the inboxes you need to send.
Provision business email addresses within your included allowance with no mailbox markup at launch. Additional inboxes, domains, taxes, and provider services you purchase independently cost extra.
FAQ
Frequently asked questions
Which mailbox providers can I connect?
MailSequence supports Google Workspace and Microsoft 365 business inboxes. OAuth authorizes mailbox synchronization; separate SMTP credentials must pass a connection test before sending. You can also provision configured business inboxes inside MailSequence.
Are inboxes included in the software price?
Yes. Each plan includes the listed allowance of provisioned business inboxes with no markup on that allowance at launch. Additional inboxes, domains, taxes, and customer-owned provider subscriptions cost extra.
Can I use a free Gmail or Outlook.com account?
MailSequence requires authenticated business inboxes on owned domains. Free consumer accounts and disposable SMTP servers are unsupported.
What must be ready before I purchase an inbox?
The selected domain must exist in the workspace and its nameservers must match the values required by the provisioning flow before mailbox purchase can proceed.
Does connecting an inbox make it ready for full volume?
No. A new or newly connected inbox should be warmed progressively and operated with conservative limits. Mailbox history, domain reputation, content, audience quality, and recipient behavior still matter.
How many inboxes can I add?
Starter supports 5, Growth 10, Scale 50, and Enterprise 200 inboxes. Per-domain limits also apply: 3, 5, 10, and 25 respectively.
