GMass users using the email auto follow-up<\/a> feature may have noticed that their auto follow-ups failed to send sometimes. Below is an explanation of when the issue surfaces and how we fixed it.<\/p>\n

The Issue<\/b><\/span><\/p>\n

If the original email campaign, to which the auto follow-ups were assigned, was larger than 1 MB, either by volume of text, or by attachment(s) that were larger than 1 MB when MIME-encoded into email format, then all stages of the auto follow-up emails failed to send. The user would not be notified of the send failure.<\/p>\n

The Cause of the Issue<\/b><\/span><\/p>\n

The cause of this has to do with how GMass processes auto follow-up emails when it’s time to send them. GMass would create a temporary Draft in the user’s account that stored pertinent details of the auto follow-up campaign. Recently, however, we discovered that Gmail Drafts are limited to 1 MB in size when the Draft is created by the Gmail API. Drafts created in the Gmail web interface do not have this limitation. If GMass attempted to create a Draft greater than 1 MegaByte with the Gmail API, an error would be returned that looked like:<\/p>\n

Error<\/span>: Google.Apis.Requests.<\/span>RequestError<\/span>
Request\u00a0<\/span>payload<\/span>\u00a0size exceeds the limit: 1048576 bytes. [400]<\/span>
Errors [<\/span>
\u00a0 \u00a0 \u00a0 \u00a0 Message[Request\u00a0<\/span>payload<\/span>\u00a0size exceeds the limit: 1048576 bytes.] Location[ – ] Reason[badRequest] Domain[global]<\/span>
]<\/span><\/span><\/p>\n

The Solution<\/b><\/span><\/p>\n

GMass is no longer using a Gmail Draft as a means of storing email auto follow-up details, and is instead creating a temporary message, which can be seen under “All Mail”. This temporary message will only live in a user’s Gmail account for a few seconds. It is deleted when an auto follow-up stage is actually sent.<\/p>\n

Now, when the auto follow-up is sent, if the original email had attachments, regardless of size, the auto follow-up email will also contain the attachment(s) from the original campaign.<\/b><\/p>\n

If you were affected by this issue…<\/b><\/span><\/p>\n

Contact our support team.<\/a> With your approval, we can manually trigger a past auto follow-up that failed to send because of this issue.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
