(there is a setting in advanced features to turn this on/off).
If turned on, then the contact does not receive the instant autoresponder message,
but would receive any follow up messages belonging to the contact group that they are added to.
If you do not want them to receive any messages then have them added to a contact group that doesn't have any messages assigned to it.
A. You can create optin forms using HTML form creator.
You can add custom fields and copy/paste the code to your 3rd party website.
A. Yes, you can integrate Pure Leverage / GVO as well as most other autoresponders besides Aweber and Getresponse. Both Pure Leverage and GVO (2 products from the same company) come installed as an option by default. As of May 2016, 9 3rd party autoresponders come installed with the software, however, most any autoresponder can be added as a
support request. If you want GVO and your software is missing it then you can add it following the
instructions for adding GVO.
