Add Confirmation to Unsubscribe Page for Short Time After Sending Campaign

[mnfctrdinitaly]

Been using Keila to send emails to members of an employee group. We've had great success sending monthly newsletters and occasional email updates about important events coming up.

As a quality assurance measure, my personal email is subscribed to the lists so that I can receive emails and view them as a recipient.

About a week ago, a member can expressed concern about no longer receiving the emails and not sure why. I looked and this member had been unsubscribed from the mailer. So I deleted their contact and re-added them to the contacts lists. But after the next email they were again unsubscribed. (Not sure how to add them again or fix this.)

I know that this must be a glitch of some kind, be cause just today MY personal email was unsubscribed and I know that I did not unsubscribe. What is causing this and how can I fix?

Did you tried the new update where the user could now resubscribe after filling the form again if he has unsubscribed ? It might not be the direct fix but this would add the functionality.

Is it possible that you or your colleague are using an email provider that automatically scans all links included in an email? In that case, an unsubscription might be triggered automatically.

Are you using your own instance of Keila or Keila Cloud?

@wmnnd Thanks for checking in!

I'm using a self-hosted instance that I deployed on a VPS.

Both subscribers were gmail accounts which very well could be the culprit.

Any thoughts on how to proceed or what steps to take to either re-add or prevent future unsubscribes?

All help is appreciated!

We also noticed this phenomenon. 14% of recipients subscribed on the first campaign, a spot check of those reported as unsubscribed told that they had not done so knowingly.

Self-hosted 0.15.0

@hyodyllinentekniikka Would you be able to share if this affected mostly users from specific email providers?

[hyodyllinentekniikka]

I did a spot check of 6 domains that appeared fairly regularly in the unsubscribed list and they all had one thing in common - their MX record pointed to <domain>.protection.outlook.com.

So perhaps Office 365/Exchange does some kind of link checking/preview that's pinging the unsubscribe link.

Unfortunately I can't see the user agent in the Keila logs :( so it's impossible to tell what sent the GET request to unsubscribe those people.

There is a solution to it. A captcha and a button can be added so the user just not only gets unsubscribed by opening the link.

@hyodyllinentekniikka, @mnfctrdinitaly Do you have an estimate on how long it took for the unsubscribe to happen after you sent the campaign? My current idea is to add a confirmation button to the unsubscribe page for 1-5 minutes after the email was sent so that automated tools don’t trigger unsubscribes.

Hi. I think the solution to the auto unsubscribe error is to add a button and a cpatcha permanently on the unsubscribe page. I mentioned it earlier but as I am flagged no one can see it. I think the setting that captcha is enabled or not should be in the form setting but button. Should be must. I also want to ask you that the form html does not work. It has site key but not the secret key in it. Is it the reason it does not work. If this is the reason I think there should be a input in the from settings for the user to put his own hcaptcha secret key so that it gets added in the code .
