Why am I seeing an AWeber captcha form?
When conducting a series of tests of your AWeber sign up form, you may notice a captcha element appear after your form submission. A captcha element would appear if the IP address used to submit the sign up form was recently used to be submitted to other AWeber lists within 12 hours.
To move forward you would need to check off the "I'm not a robot" checkbox. As long as your subscribers are not submitting through the same IP Address, this will not appear for them.
