Terms of Service

Use day3 to send email to people who agreed to hear from you. Pay your bill. Don't abuse the service or other people's inboxes. We'll keep the lights on and treat you fairly.

You're responsible for your account, your sending domain, and the content of the campaigns you send. Keep your credentials safe and make sure the people on your lists actually opted in.

day3 is for sending wanted email to your own audience. The following are not allowed:

• Purchased, scraped, or rented lists.
• Cold outreach to people who never opted in.
• Misleading sender identity, subject lines, or unsubscribe links.
• Unlawful, harmful, or deceptive content.

Every campaign includes one-click unsubscribe and honors opt-outs immediately. Senders with poor deliverability metrics may be paused.

Plans are billed monthly and priced by emails sent. Subscribers are always unlimited and free. You can change or cancel your plan at any time; changes apply from the next billing period.

We may update these terms as the product grows; we'll note the date above when we do. Questions? Email hello@day3.app.
