In other words, are people filling out your capture form but not confirming their subscription request?
Your confirmation message may be getting sent to the spam folder.
Your confirmation message may just not be getting a good click-through.
We recommend using a custom confirmation message.
If you are using the default confirmation message, your confirmation message looks like thousands of other confirmation messages. This makes it easy for major email service providers to mark your message as spam and send it to the spam or junk folder.
Beyond that, when your message makes it to the inbox, a custom confirmation message can help you improve your optin rates by reminding your subscribers what they opted in to receive.
The extra minute or two that it will take to create a custom confirmation message is time well spent when you improve your deliverability and your confirmations.
