Verification emails are automatically sent as soon as you complete the signup form and should never take more than 30 minutes to receive. If you haven't received yours after an hour, please visit your member area to have it resent.
If you still don't receive your verification email address after having it resent, then your email provider is most likely blocking it.
If they provide you with an option to 'white-list' email domains and addresses, make sure to add adsolutionline.com to your allowed domains list or try a different email address.
