How to cancel SeaArt by mail
Get your account details together
Have the account email, the plan or product name and the invoice or order number from your latest receipt to hand. The details in the letter need to match what SeaArt has on file.
Prepare the letter
The letter asks SeaArt to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 068809 Singapore. Keep the tracking number it gives you.
Keep the delivery receipt
Once the letter is delivered, the date on the receipt is the date SeaArt was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your SeaArt cancellation letter goes
Written requests to SeaArt go to 6 Shenton Way, #37-03, OUE Downtown, 068809 Singapore, Singapore.
The envelope is going to Singapore, Singapore, so the postcode 068809 must be on the front.
Your details go in a block headed by Account holder, Billing address on file and Email on file, and the opening line is “To Whom It May Concern,”.

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.
