How to add and verify your sending domain
Verifying your domain proves that you are authorized to use it to send emails. Authentication also helps to improve deliverability, and helps with brand reputation and trust, as your messages will appear in inboxes with your domain as the sender.
How to add and verify a sending domain
Please note that you need to have access to the domain’s DNS records so you can verify your domain. If you do not have access, after you add you domain, you can click Forward instructions on the domain's DNS settings page to send the DNS records to the person managing your domain.
Add a domain
1. Navigate to Email > Domains in the left-hand navigation menu.
2. Click on Add domain.
3. Enter your domain name and click Add domain. You will be prompted to connect your domain automatically.
Automatic domain authentication
Automatic domain authentication involves logging in to your domain registrar account and authorizing access for the DNS records to be added automatically for you. If you'd like to proceed with automatic domain verification, click Continue and follow the steps.
If you prefer to add your domain records manually, simply close the pop-up.
Manual DNS configuration
If you skip automatic domain authentication, you will see instructions for adding DNS records to your domain’s DNS page.
If your provider is able to be identified by MailerSend, you will see specific instructions for that provider, such as GoDaddy or IONOS. If not, you will see general instructions for adding DNS records.
Although each provider has their own format for accepting records, all platforms will provide the following options needed for MailerSend when adding new records:
SPF: Sends the mail server IP validationÂ
DKIM: Like SPF, but uses cryptographic methods for validationÂ
CNAME for Return-Path: The address where bounces and other email feedback are sent to. It’s specified by the Return-Path header in an email
You can click on each field value to automatically copy it.
To add Custom DNS records for tracking or enable Inbound domain forwarding, toggle the following options ON.
To manually configure your domain's DNS records:
1. Log in to your domain registrar account and locate the DNS settings for your domain.
Remember, you can also share the instructions by clicking Forward instructions. Doing so sends an email with instructions about how to set up the DNS records to the email addresses you provide.
2. After adding the records, check the option I have added DNS records and click Finish verification. Once the records have been propagated, your domain will be verified and ready to use.
Once your records have been added, authentication typically completes within a few minutes. But this depends on provider and can take up to 48 hours. If after 48 hours, your domain still isn't verified, double-check that you've added the records correctly and try clicking Re-check now on the DNS page. If after another 48 hours, your domain still hasn't been verified, contact our support team for assistance.
DMARC
DMARC (Domain-based Message Authentication, Reporting, and Conformance) serves as a key tool in safeguarding your domain against email-related threats like spoofing and phishing, especially for domains that send out transactional emails.
This enhances email security by preventing unauthorized emails from posing as your domain, protecting your domain's reputation. What's more, it helps you to easily identity issues with your authentication, giving you insights to help tighten security and move toward a stricter DMARC policy.
Incorporating a DMARC record, a specific TXT entry in your domain's DNS settings, helps define your DMARC policy and instructs how email servers should handle messages that don't pass SPF or DKIM validations.
Starter plans have 30 days of free access to DMARC monitoring, after which it is available as an add-on, while Professional plans have a number of DMARC monitors included. The DMARC monitoring tool enables you to create a DMARC record for your domain and monitor activity with reports.
Learn more about DMARC and how to use the DMARC monitoring tool to generate a DMARC record and analyze domain sending activity.
How to set up Custom DNS records for tracking
When sending emails with MailerSend, you can track opens and clicks for the emails sent through your domain. If you plan on using tracking options, you can use custom link branding.
To set this up, toggle the Custom DNS records for tracking option in the Domain verification page of the domain.Â
When this option is enabled, you’ll need to create one more CNAME record for your domain.
By default, we use the subdomain email.yourdomain.tld. That means that your tracking links will be: email.yourdomain.tld/unique-id-for-unique-link
If you want to change the subdomain to anything else:
1. Click Edit and enter any available subdomain under your domain and save it.
2. Head to the domain’s DNS page and create the CNAME record with the fields provided on the Domain verification page.
Once you’ve added the record and it has propagated, all tracking links will use this custom domain name. You can edit this option at any time.
How to troubleshoot the authentication process
If you’ve added all required records in your DNS zone and you’ve waited for a while, but still see that your domain is marked as unverified:
Check that the fields of all records have been entered correctly in the DNS page of your sending domain (they are case-sensitive).
Check if the DNS page has only 1 SPF record. If there’s more than 1 SPF record, the domain won’t be authenticated. Take a look at How to merge SPF records to continue.
Toggle the option I have added DNS records once again and click on Re-check now.
If your records look correct and the domain is still unverified after 48 hours, feel free to contact our Support team at support@mailersend.com.Â
