How to cancel Omnisend LLC by mail
Start with your account details
Before writing, collect the account email, the plan or product name and the invoice or order number from your latest receipt. Omnisend LLC can only act on a request it can match to an account.
Put the request in writing
State plainly that you want the Omnisend LLC account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – Omnisend LLC”).
Send it by certified mail
Use certified mail for the 19801 Wilmington address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
Delivery confirmation is your evidence that Omnisend LLC was asked. Watch the next statement or two for any further Omnisend LLC charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
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.
