After doing a lot of tests, I've decided to continue using the GWA Autoresponder. Due to the other autoresponder not delivering emails daily during the test, I stopped using it. So now all emails will be handled by the GWA Autoresponder. There is a newsletter signup form on both my sites. To access the one on Weebly Barry Selk Marketing site, just click on Newsletter! -> Start Here! on the left.
