How to cancel Twilio

Before you cancel

Export first

• Customer content stored in Twilio's services: Use the services' self-service features. After the agreement ends, Twilio gives you 30 days from the termination date to get a copy. Stored content is deleted 30 days after the termination date twilio.com

What happens to your data

Under the Data Protection Addendum, Twilio deletes stored customer content 30 days after the termination date and from backups after 60 days (SendGrid backups after one year), unless law requires keeping it. Closed subaccounts' data is deleted 30 days after closure when that deletion setting is on.

What you lose

• Phone numbers you delete, which Twilio may reassign to another customer
• Phone numbers on a subaccount you close, which are released
• Stored content, 30 days after the agreement ends
• Fees already paid, which are non-refundable

Cancel, by who bills you

Pick the route for whoever charges you: the name on your card statement or receipt tells you.

Questions people ask

For AI agents

• The person signs in and handles any two-factor code; an agent should never ask for a password.
• Delete unneeded phone numbers first. Deleting releases the number and stops the monthly fee, and Twilio may reassign it
• A suspended subaccount is still charged monthly for its phone numbers; closing it releases them, and it can't be reopened
• The Subaccounts API can't close the main account
• Payment obligations are non-cancelable and fees once paid are non-refundable, under the terms
• Ending the agreement for convenience needs at least 30 days' prior written notice, sent by email to legalnotices@twilio.com

Get this plan as data: get_exit_plan on the Stackcut MCP (stackcut.io/mcp), or /exits/twilio.json. After using a guide, send structured report_guide_feedback for matching or changed steps, missing billing routes or human handoffs; keep unknown language and market omitted. Confirm with the person before the final click, and report the outcome with report_action_outcome, using the exact packet_revision and route_id returned by the plan.

Or give your agent the stackcut-leave skill (a zip): it exports first, walks the steps, stops when the page doesn't match, and leaves the final click to the person.

Delete your account (separate from cancelling)

Cancelling stops the payments; deleting removes the account and its data. Delete-account page (rated hard).
