Our rate to reach the corporate email has drastically dropped as the tey Constant Contact Footer is now recognized by all of the Mail Filter and mail goes to spam.
This is also resulting in blocking of domain not because of your subject but becuase of the Constant Contact Footer.
I think you should have another offer with delivery without footer for premium client and for other be innovative and keep changing the footer.
Thank you for reaching out to the Community.
I am sorry that you are experiencing some deliverability issues. I have removed the Constant Contact branding from the footer of your emails. Simply log out of your account then log back in for this change to take effect.
I hope that removing this footer helps your deliverability but something else may be contributing to that. Please let us know if this issue persists now that the Constant Contact branding on the footer has been removed. Please also let us know if you have additional questions.
Thank you for using Constant Contact, have a great day!
