How to cancel Arch Capital Group by mail
Start with your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Arch Capital Group is the easiest one to set aside.
Write your request
Postbye writes the letter in Spanish from our Spanish template, because Arch Capital Group's address is in Spain. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Arch Capital Group to end the subscription, stop all further charges and confirm in writing.
Post the letter
Take the letter to the post office and ask for certified delivery to 28004 Madrid. Keep the tracking number it gives you.
Keep proof the letter arrived
Keep the tracking record with your copy of the letter. If Arch Capital Group bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Arch Capital Group, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
