Email deliverability is a huge problem for online businesses. In fact, according to recent studies, as many as 30% of all emails sent are never received by the intended recipient. And of those that are received, a significant portion will end up in the recipient’s spam folder.
Many factors contribute to poor email deliverability, but one of the most important is your domain reputation. Your domain reputation is basically how ISPs view your email-sending practices. If you have a good domain reputation, your emails are more likely to be delivered to the inbox. If you have a bad domain reputation, your emails are more likely to be sent to the spam folder.
One of the best ways to improve your domain reputation is to set up an SPF record. SPF stands for ‘Sender Policy Framework’ and it’s a way to verify that the sender of an email is authorized to send an email on behalf of a specific domain. By setting up an SPF record for your domain, you can help improve your email deliverability and protect your domain reputation.
In this article, we’ll show you how to create an SPF record for your domain. We’ll also cover some of the benefits of using an SPF record and answer some common questions about SPF records.
So let’s get started…
What is an SPF record?
An SPF record is a DNS TXT record that specifies which mail servers are authorized to send mail on behalf of your domain. By publishing an SPF record, you can help to prevent email spoofing and protect your domain’s reputation.
When a receiving mail server receives an email, it can check the SPF record for the sender’s domain to verify that the email is coming from an authorized mail server.
If the email is not coming from an authorized mail server, the receiving mail server may mark the email as spam or even reject it outright.
Creating an SPF record can be daunting, but there are tools available to help you. Once you’ve created your SPF record, you’ll need to publish it in your DNS records. You can do this yourself if you have access to your DNS records, or you can contact your DNS provider and ask them to help you.
How to create an SPF record for your domain
The first step is to determine which specific IP addresses are allowed to send an email on behalf of your domain. This can typically be found in your Email Service Provider’s (ESP) documentation. Once you have that information, you’ll need to create a text record with the following syntax:
v=spf1 mx a ip4:XXX.XXX.XXX.XXX/XX include:mutantmail.com ~all
Replace the XXX.XXX.XXX.XXX/XX with the IP address(es) from your ESP, and update the ~all to -all if you want to fail any email that doesn’t come from a specified IP address.
Once you’ve created your SPF record, you’ll need to publish it in your DNS records. You can check our knowledge base for provider specific process. Last step would be, to contact your domain registrar or DNS provider for help.
Benefits of using an SPF record
1. It can help protect your domain reputation: By specifying which servers are authorized to send an email on behalf of your domain, you can help prevent malicious actors from spoofing your domain and sending spam or phishing emails. This can protect your domain from being blacklisted by email providers, which can result in deliverability issues.
2. It can improve email deliverability: By aligning your SPF record with your email provider’s policies, you can increase the chances that your emails will be delivered to the inbox rather than the spam folder.
3. It can save you money: By preventing malicious actors from sending spoofed emails on your behalf, you can avoid the cost of having to clean up your domain reputation if your domain becomes blacklisted.
4. It can simplify email administration: By centralizing information about which servers are authorized to send an email on behalf of your domain, you can make it easier to manage your email infrastructure.
What is an SPF record?
An SPF record is a type of Domain Name System (DNS) record that helps to prevent email spoofing. Email spoofing is when someone sends an email with a forged “From” address that appears to be from a different domain. SPF records help to verify that the email is truly coming from the domain it claims to be coming from, and they can help to prevent your emails from being marked as spam.
How to troubleshoot SPF issues
If you’re having trouble with your SPF record, there are a few things you can do to troubleshoot the issue. First, check to make sure that your SPF record is published correctly. You can use a tool like Slim Domain to check your record and make sure it’s being published correctly.
If your SPF record is published correctly but you’re still having trouble, it’s possible that your ISP or email provider is not recognizing your SPF record. In this case, you’ll need to contact your ISP or email provider and ask them to configure their systems to recognize your SPF record.
Finally, if you’re still having trouble, you can try using a different SPF record format. There are several different formats for SPF records, and some ISPs and email providers only recognize certain formats. Try using a different format and see if that solves the problem.
The takeaway from all of this is that if you want to ensure optimal email deliverability for your domain, you need to have a valid SPF record in place. This will help protect your domain reputation and ensure that your emails are delivered to the inbox rather than the spam folder.
One last thing to keep in mind is that SPF records can be complex, so it’s important to consult with an expert if you’re unsure about anything. There are a lot of moving parts involved in setting up an SPF record, so it’s better to be safe than sorry. If you follow the advice in this article, you should be well on your way to creating a valid SPF record for your domain. Just remember to keep it updated as your email infrastructure changes, and you’ll be good to go.
