The website (only) host is https://www.ecowebhosting.co.uk/, and all other (mail, ftp, etc) hosting is bluehost for the keepingroomchristiancounseling.com domain.
Using the MailPoet sending service.
So far as I know, only readers with Comcast domain emails are not receiving notifications. And I’m 99% sure that issue only started within the last week. Using MP v3.
Thanks.
