1. Introduction
If you are using Omnisend to send emails, this article is for you! If you have not set up Omnisend DMARC, SPF, and DKIM records, your Omnisend emails may be blocked. Email verification is mandatory for Google and Yahoo's email sender policies. Whether you send bulk mail or not, you need to implement at least one of these protocols to send your mail.
DMARC implementation is very important for your Omnisend sending domain
Domain-based Message Authentication, Reporting, and Conformance) helps you phone number list set up your email authentication strategy. DMARC is a multifaceted protocol with a feedback mechanism that also helps you monitor the results of your authentication. If you want to improve your email security by preventing phishing attacks, DMARC can help you!
（二）Before configuring DMARC for Omnisend, you must understand the various DMARC policy modes. The Omnisend DMARC policy you configure will determine how recipients handle the following email checks.
(iii) While Omnisend recommends keeping your DMARC policy at "None" and relaxing the settings, we do not recommend this. This is because a "None" policy can make you vulnerable to phishing attacks. To prevent domain abuse, you must configure DMARC to "Isolation" or higher. With adequate monitoring, a strict policy will not affect your sending capabilities.
3. To configure Omnisend DMARC, you can follow the steps below
(a) Sign up for SecurityGateway for free to analyze and we'll instantly generate a comprehensive report telling you whether you have DMARC implemented.
2. Use our tool to create a record for configuring Omnisend DMARC. You can configure several criteria in the record. Not all conditions are mandatory. When creating the syntax, make sure to mention the protocol version (v=DMARC1) and the policy mode (p=).
(iii) When you first deploy DMARC, start with "None". Then, we will slowly help you move to "Reject". DMARC enforcement (p=reject) should be your ultimate goal to prevent domain impersonation.
DMARC protocol can only work properly after the record is published on DNS. In this step, you need to access the DNS management console. If you do not have access, please contact your domain hosting provider to complete the implementation.
5. Finally, check your Omnisend DMARC record to confirm that it is valid. An incorrect record will completely invalidate your DMARC setup. Use our tool to accurately check your record.
Yes. If you are familiar with the technical syntax, you can create your own DMARC record. We have a
will help you better understand DMARC record syntax! However, using a trusted third-party vendor will make the whole process easier, less time-consuming, and requires no technical expertise!
5. Omnisend SPF record helps you authorize the sending source
Sender Policy Framework (SPF) is an email validation protocol. With SPF, you can publish a list of safe senders in DNS. If someone outside the authorized senders list sends an email impersonating you, the email will fail SPF validation. This is an important step in preventing spoofing and phishing.
6. To set up SPF for Omnisend, you need to update an existing SPF record or create a new one. Please follow the steps below to create a new record:
1) Sign up for SecurityGateway for free and select our tool. This tool is great for automatically generating SPF records! In this step, you need to enter "mailgun.org" in the "Authorized Third Party Domains" field of the SPF Generator tool. Omnisend uses Mailgun to send emails. By authorizing mailgun, you are establishing Omnisend as a trusted sender.
(ii) The SPF configuration will only take effect after the record is published on DNS. In this step, you need to access the DNS management console. If you do not have access, please contact your domain hosting service provider to complete this step.
3) Finally, check your Omnisend SPF record to confirm that it is valid. If the record is incorrect, your SPF setup will be completely ineffective. Use our tool to accurately check your record.
