With the rapid evolution of the digital landscape, it is crucial for businesses to adapt their strategies email marketing<\/a>. The changes announced by Google and Yahoo are not merely minor tweaks, but fundamental overhauls that could redefine how businesses communicate with their customers. For example, studies show that properly authenticated email campaigns can increase open rates by up to 30%, underscoring the importance of email domain authentication.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Google and Yahoo are announcing significant changes to their email policies, aimed at combating spam, particularly concerning email domain authentication. These modifications are set to take effect starting February 1, 2024, for Gmail accounts and in the first quarter of 2024 for Yahoo accounts. The main changes are as follows and will apply to bulk email senders, defined as those sending more than 5,000 emails per day. Be aware, this news might seem minor, but when ISPs decide to change the rules, it's best to follow them... These rules are valid for both individual and mass, automated sends via\u00a0API<\/a>\u00a0and for manual shipments on\u00a0web interface<\/a>.\u00a0\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

It is also important to note that users are becoming increasingly security-conscious. When companies use proper authentication, they demonstrate to their customers that they take security seriously, which can build trust and improve customer relationships. For example, an online retailer that implemented protocols such as DKIM and DMARC saw a 40% reduction in spam complaints over the course of a year.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

DKIM, SPF & DMARC required for domain authentication<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In parallel, it's interesting to see how different companies manage to implement these protocols. Let's take the example of a tech startup that recently migrated to a cloud infrastructure. By integrating SPF and DKIM from the outset, they not only improved their deliverability but also allowed their marketing team to access valuable analytical data that helps them refine their campaigns. The results were impressive, with a conversion rate that doubled in a few months.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Messages sent to your account must have all valid email settings: SPF<\/strong>, DKIM<\/strong> and DMARC<\/strong>.<\/a> DMARC can be set to the least restrictive policy (none<\/code>), making it possible to monitor shipments without blocking those that fail authentication. Although the current obligation only applies to senders sending more than 5,000 emails per day<\/strong>we strongly recommend that you SPF, DKIM and DMARC<\/strong>, whatever your shipment volume<\/strong>.<\/p>

These protocols reinforce server trust\u00a0SMTP<\/a>\u00a0of reception<\/strong> and email authentication by proving that your messages are indeed sent from authorized sources, which limits the risks of phishing and identity theft<\/strong> and classification spam<\/strong>. Their implementation improves your email deliverability<\/strong>protects your sender reputation<\/strong>and allows you to track fraud attempts via DMARC reports.<\/p>

What's more, with the rise of intelligent spam filters and the increasing demands of services such as Gmail, Outlook and Yahoo, 100% compliance is becoming essential to ensure that your emails reach your recipients' inboxes.<\/p>
