How to cancel Iqnio by mail
Find your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Iqnio is only as good as the details it quotes.
Prepare the letter
The letter asks Iqnio to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Iqnio”. Postbye fills it in from our English template.
Send the letter by certified mail
Use certified mail for the 33160 Sunny Isles Beach address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
Keep the tracking record with your copy of the letter. If Iqnio 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 Iqnio, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
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.
