![]() Each key is produced by my sender, ensuring that emails sent by a spammer can’t get spoofed. Domain-based Message Authentication, Reporting and Conformance ( DMARC) – this newer standard has an encrypted key that can validate both my domain and the sender.For example, I send emails for Martech Zone from Google Workspace. Sender Policy Framework ( SPF) – the oldest standard around, this is where you register a TXT record on your domain registration ( DNS) that states what domains or IP addresses you are sending emails from for your company.The best practice for mitigating any inbox placement issues is to ensure you have set up email authentication records that ISPs can use to look up and validate that the emails you are sending are truly sent by you and not by someone pretending to be your company. You can use many services to monitor your IP reputation, but I’d be a bit pessimistic since many don’t have insight into each ISP’s algorithm. There are blacklists that ISPs may use to block all of your emails altogether, or you may have a poor reputation that would get you routed to the junk folder. Reputation – ISPs and third-party services also maintain reputation scores for the sending IP address for your email.My company can provider this testing for you as well. To truly monitor your inbox placement, you must use a seed list and look at each ISP to identify whether your email landed in the inbox or the junk folder. An email routed directly to the junk folder and never seen by your email subscriber is technically delivered. Inbox Placement – ESPs consistently promote high deliverability rates that are nonsense.The ISPs assume you’re a spammer or sending malicious emails… unless you prove otherwise. You can do everything right as a business to acquire permission and email addresses, and the ISP has no idea and may block you anyway. It’s an inherently flawed system that has skyrocketed fraudulent schemes like phishing. Permission – Email service providers ( ESPs) manage the opt-in permissions… but the internet service provider ( ISP) manages the gateway for the destination email address. ![]() There are three invisible problems with email deliverability that businesses are unaware of: The attacker will send an email that appears to be from a legitimate source, then bring you to a landing page that you believe is a login or other authentication page where the victim inadvertently enters their personal information. Phishing is a cyber-attack where individuals or organizations try to trick people into revealing sensitive information, such as passwords or credit card details, by disguising themselves as trustworthy entities. PhishingĪt issue is the growing issue of malicious and fraudulent emails, especially phishing emails. Most companies don’t even realize they have a problem they think subscribers simply aren’t engaging with their emails. We work with many companies assisting them with their email migration, IP warming, and deliverability issues. If a result is found, this constitutes a match.įor a modifier redirect=domain, the SPF record for domain replaces the current record.If you’re sending any significant volumes of marketing emails, chances are your email is not making its way to the inbox if you’ve not configured your email authentication. Perform an A query on the provided domain. If a valid hostname ends in domain, this mechanism matches. The hostnames are then validated: at least one of the A records for a PTR hostname must match the original client IP. The hostname or hostnames for the client IP are looked up using PTR queries. If the client IP is found among them, this mechanism matches. If the connection is made over IPv6, then an AAAA lookup is performed instead.Īll the A records for all the MX records for domain are tested in order of MX priority. If no prefix-length is given, /128 is assumed (singling out an individual host address).Īll the A records for domain are tested. The argument to the "ip6:" mechanism is an IPv6 network range. ![]() If no prefix-length is given, /32 is assumed (singling out an individual host address). The argument to the "ip4:" mechanism is an IPv4 network range. If the lookup does not return a match or an error, processing proceeds to the next directive. The specified domain is searched for a match. It usually goes at the end of the SPF record.
