Can an End User request removal of email address incorrectly added to USPS suppression list?

[smtangy]

I stopped receiving daily Informed Delivery email from USPS for awhile now.  If I switch to different email addresses, they all work except one.  I believe the "non working" address may have been incorrectly added to Sinch suppression list.  As a consumer, how do I go about removing the address from Suppression list?

Hi smtangy,

Can you please confirm which Sinch product you are using? We can then look into getting your issue resolved for you ASAP.

Thanks and kind regards,
