domain sms blacklist
Hello - I'm the CTO for our company and we've suddenly started receiving customer complaints that when they SMS text others a link that includes our domain it is being blocked/filtered out. Is there some place I can check to see if our domain has been blacklisted by AT&T and how do we go about fixing this? (email does not appear to be an issue, all RBL reports show our domain as clean, SPF, DKIM are all properly configured and we get daily DMARC reports confirming deliverability... this appears to be localized to SMS text only.) Please advise. Thank you!
