What safeguards are there against spam?
We have built in confirmation emails sent from the platform itself. If that is turned on and no one clicks the confirmation link then the lead isn't activated and the email address doesn't get added to the user's autoresponder.
Once the confirmation email is clicked and confirmed, the submitted email from the form gets added into the user's autoresponder
There isn't any way to stop someone entering someone else's email into a form BUT switching on confirmation emails resolves this issue.
To ensure you don't get bots subscribing, simply turn on the 'confirmation first' email setting and only confirmed subscribers will be added to your autoresponder and campaigns.
