From February 2024, services like Gmail or Yahoo Mail will require DMARC settings from senders. Especially those sending bulk messages and newsletters.<\/p>\n<\/blockquote>\n\n\n\n

To improve email delivery and increase results for message recipients, your domain settings need to be optimized. Gmail or Yahoo’s email servers can mark an email message as SPAM or stop it entirely due to missing settings. In this guide, we cover basic optimization and domain settings for smooth email flow.<\/p>\n\n\n\n

A free tool that can improve classification of specific messages or reveal why a message was marked as SPAM is called Mail Tester<\/a>. The tool checks the score for a specific email message and suggests how to improve your sender reputation and email delivery.<\/p>\n\n\n\n

SPF<\/h2>\n\n\n\n

An SPF record<\/strong> (Sender Policy Framework)<\/em> is a type of TXT record<\/strong> that contains information about which SMTP servers (IP addresses) are authorized to send email from a specific domain. The goal of SPF is to limit sender spoofing in email and prevent spam.<\/strong><\/p>\n\n\n\n

How to set up an SPF record<\/h3>\n\n\n\n

If you send email messages from WebSupport, your SPF record will look like this: v=spf1 a mx include:spf.websupport.se ?all<\/p>\n\n\n\n

This record says that smtp.websupport.se is the authoritative SMTP server for your domain. Since the IP addresses the SMTP server sends from (smtp.websupport.se) are also in the SPF record, the message will be delivered.<\/p>\n\n\n\n

If the message is sent via a different SMTP server, for example smtp.gmail.com, the email loses points in its evaluation and will likely be marked as spam.<\/p>\n\n\n\n

SPF is a TXT record<\/strong>, so you can set it up in DNS > TXT.<\/p>\n\n\n\n

How do you edit TXT records? \u00bb<\/a><\/p>\n\n\n\n

Changes made through our DNS settings will only take effect if your domain has name servers set to WebSupport (ns1.loopiagroup.com). When you set up the SPF record, make sure you’ve set Name servers<\/strong> to WebSupport. If you use your own name servers or another provider’s NS, ask them to add an SPF record in their DNS manager.<\/p>\n\n\n\n

Combining multiple SPF records<\/h3>\n\n\n\n

You can only have one TXT record for SPF in your DNS. If you need to enable sending from multiple servers, you must combine SPF records into one.<\/p>\n\n\n\n

For example, if you need to add a Google SPF record to our SPF record, you can do it like this:<\/p>\n\n\n\n
