Stopped receiving emails while using subscribe API

Question

Dear Klaviyo Support Team,I am reaching out to report an issue I have encountered while subscribing to a list via the Subscribe API /api/profile-subscription-bulk-create-jobs/ (v2023-02-22).Despite receiving an "Accepted" response with a status code of 202 from the API, I have stopped receiving confirmation emails when attempting to subscribe to a list with double opt-in enabled. While the initial attempts were successful and confirmation emails were received.However, I have noticed that the Subscribe API is functioning correctly when single opt-in is enabled, and both emails and SMS are being successfully subscribed to the lists.I kindly request that you investigate this issue and provide a resolution as soon as possible.Thank you for your attention to this matter.Best regards,

Hey @hafiza,Sorry to hear about your experience!In addition to theUnderstandinglistbombingHelp Center article @Brian Turcottelinked, I would suggest taking a look at some past Community posts that touch upon this subject. I’ve included some below that I know others have found helpful:Were you trying to add users to a list? If so, I would recommend importing them as a .CSV until our list bombing security protocol has gone through its process.David

Hi@hafiza!This is likely due to our protocol that preventslist bombing,which may have halted the confirmation emails.Support will be able to assist you with this, so I am going to get you in touch with themso they can clarify.Best,Brian
