Terms of Service

Last updated October 7, 2026

These terms cover your use of GmailFlow. By signing in, you agree to them. If you use GmailFlow for a company or other organization, you agree on its behalf and confirm you have the authority to do so.

The Privacy Policy explains how we handle personal data, and is part of these terms.

The service

GmailFlow sends email sequences from the Gmail and Google Workspace mailboxes you connect, and stops a recipient's sequence when they reply. What you can do, and how much you can send, depends on your plan.

Your account

Teams

Everything in GmailFlow happens in a team. When you sign up, you create a team of your own and choose its plan, or join a team you were invited to, and you can create more teams. A team's owner can invite people to join it, and decides which members can use each of its mailboxes. The owner can remove members, make another member the owner, and delete the team. Members can leave a team at any time.

If you own a team, you're responsible for who you invite and for what its members do in it.

Connecting Gmail

When you connect a mailbox, you authorize GmailFlow to send email from it and to read the headers of its messages, to detect replies and bounces and to check that its emails went out. You must own the mailbox or have permission to connect it. The mailbox belongs to the team you connect it in: the team's owner decides which members can send from it, and it stays with the team if you leave.

Google's own terms and policies still apply to your mailbox. Google sets its own sending limits and can restrict or suspend a mailbox for reasons we don't control, and we aren't responsible for what Google does with your account. A team's owner can disconnect any of its mailboxes in GmailFlow, and so can whoever connected one while they can still use it. You can revoke GmailFlow's access from your Google Account at any time.

Acceptable use

You're responsible for the email you send with GmailFlow. You must:

GmailFlow adds unsubscribe headers to every email and stops emailing anyone who unsubscribes. Don't work around that. You also must not:

Your content

The templates, campaigns and contact data in a team belong to that team, whoever put them there. Its owner controls them, and they stay with the team when a member leaves or deletes their account. You let us store, process and send them only as far as we need to provide the service. For a team's contacts' personal data, the team's owner is the controller and we process it on their behalf, as the Privacy Policy describes.

Plans and billing

Suspension and termination

You can stop using GmailFlow and delete your account at any time from Privacy settings or your Account page. If you own a team that has other members, you first make one of them its owner or delete the team. A team's owner can delete it from its settings.

We may suspend or close your account if you break these terms, don't pay, or use GmailFlow in a way that puts other customers, our systems or our standing with Google at risk. Where we can, we'll warn you first and give you time to export your data. Once an account is closed, we delete its data as the Privacy Policy describes.

Changes to the service

We may add, change or remove features, including what each plan includes. If a change takes away something you pay for, we'll tell you in advance.

Disclaimers

GmailFlow is provided "as is" and "as available". We don't promise that it will run without interruptions or errors, that your emails will land in the inbox, or that it will classify every reply, automatic reply and bounce correctly. Open and click counts are estimates, because privacy features in some email apps and corporate link scanners open emails and follow links on their own.

Limitation of liability

As far as the law allows, GmailFlow isn't liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill. Our total liability for any claim about the service is limited to what you paid us in the 12 months before the claim arose. Nothing in these terms limits liability that the law doesn't allow us to limit.

Indemnity

You'll defend and compensate GmailFlow against claims and costs that come from the email you send, the contact data you upload, or your breach of these terms.

Third-party services

GmailFlow relies on Google and Stripe, and their own terms apply when you use them. Gmail and Google Workspace are trademarks of Google LLC. GmailFlow isn't affiliated with or endorsed by Google.

Changes to these terms

We may update these terms. When we do, we change the date at the top, and we email you about significant changes before they take effect. If you keep using GmailFlow after that, you accept the new terms.
