That third guideline from Google and Yahoo is no joke. Their <strong>security filters<\/strong> will only allow <strong>authenticated emails<\/strong> through.<\/p>\n<p>To comply with this, bulk senders are <strong>required<\/strong> to set up SPF, DKIM, and DMARC together. If you send fewer emails, you'll have less work ahead. However, you'll still need to set up SPF or DKIM, combined with DMARC.<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h4 class=\"wp-block-heading\">SPF, DKIM, and DMARC?<\/h4>\n<p>Here are the three terms explained:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.combell.com\/en\/help\/kb\/create-spf-record-to-keep-your-e-mails-out-of-the-spam-filter\/\" target=\"_blank\" rel=\"noreferrer noopener\">SPF<\/a> (Sender Policy Framework)<\/li>\n<li>DKIM (DomainKeys Identified Mail)<\/li>\n<li><a href=\"https:\/\/www.combell.com\/en\/help\/kb\/better-e-mail-delivery-with-dmarc\/\" target=\"_blank\" rel=\"noreferrer noopener\">DMARC<\/a> (Domain-based Message Authentication Reporting and Conformance)<\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<p>For those familiar with the world of email marketing, these technical terms should be well-known. For those less acquainted: SPF, DKIM, and DMARC have been established for several years as the <strong>best ways to secure your emails.<\/strong><\/p>\n<p>SPF is a protocol that specifies who is authorized to send email on your behalf or on behalf of your business. DKIM, on the other hand, is a form of digital signature.<\/p>\n<p><a href=\"https:\/\/www.combell.com\/en\/help\/kb\/better-e-mail-delivery-with-dmarc\/\" rel=\"noreferrer noopener\" target=\"_blank\">DMARC<\/a> serves as an additional layer of security. It determines what should happen to an email if it doesn't meet the standards of SPF or DKIM. While DMARC is useful, unfortunately, it's <strong>not yet widely adopted<\/strong> by most companies.<\/p>\n<p>This <a href=\"https:\/\/flexmail.be\/en\/knowledge-center\/everything-you-need-to-know-about-email-authentication\" rel=\"noreferrer noopener\" target=\"_blank\">blog article<\/a> provides a detailed explanation of what SPF, DKIM, and DMARC mean and how they work.

Plenty of options!\"<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Be stricter when sending emails<\/h3>\n<p>\"Many don't think about this, although it's so logical. You can increase the strictness of your email communication by, for example, only sending emails from specific IP addresses. Include those IP addresses in your SPF record and ensure that list remains as limited as possible.<\/p>\n<p>You can do this if you want more certainty about the delivery of your emails. The spam filters of Gmail and Yahoo will recognize your IP address.\"<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Use the Combell server as an SMTP server<\/h3>\n<p>\"It's the SMTP server that sends your email to your recipient. Then your contact retrieves the email from an email server using POP or IMAP. Using Combell as an SMTP server is not only better for delineating your SPF, it's also much safer.\"<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Work via a specialized email tool<\/h3>\n<p>\"Look, at Combell, we really do a lot to protect our customers. I've experienced situations where a customer suddenly starts emailing from thirteen countries simultaneously. That's immediately suspicious. As soon as we notice that, we proactively block all those emails and ask the customer to reset their password as a precaution.<\/p>\n<p>But if you really want to get serious about email marketing, you need specialized tools. Sending mass emails from a regular mail program is asking for trouble.<\/p>\n<p>At <a href=\"https:\/\/www.combell.com\/en\/email-hosting\/email-marketing\" target=\"_blank\" rel=\"noreferrer noopener\">Flexmail<\/a>, all they do is ensure the highest delivery rates. That's their core business. Moreover, DMARC is included as standard with Flexmail.\"<\/p>\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Gmail (Google) and Yahoo are implementing stricter email security rules for incoming emails.
