How to Verify Your Sending Domain with Amazon SES in MailWizz

If you’re running MailWizz with Amazon SES, you already know that domain verification is one of the most important steps to ensure your emails actually reach the inbox. But if you’ve ever gone through the process manually, you also know it can be a headache.

DNS records are easy to misconfigure. A wrong DKIM value here, a missing SPF record there — and suddenly your carefully crafted email campaign is landing in spam folders instead of inboxes.

This guide walks you through exactly how to verify your sending domain with Amazon SES inside MailWizz, what records you need, and how an extension can turn this tedious process into something your customers can actually handle on their own.

Why Domain Verification Matters

Before we dive into the how, let’s talk about the why.

Amazon SES requires you to verify every domain you send from. This isn’t just a bureaucratic checkbox — it’s a critical layer of trust. When you verify a domain, you’re proving to Amazon (and to mailbox providers like Gmail, Outlook, and Yahoo) that you actually own that domain and have permission to send emails from it.

Verified domains enjoy:

• Higher deliverability — Verified domains are trusted more by mailbox providers
• Better sender reputation — Proper authentication protects your reputation
• DKIM signing — Automatic signing of outgoing emails
• MAIL FROM customization — Control over bounce handling
• Protection against spoofing — Prevents others from faking your domain

Without proper verification, you’re essentially flying blind. Your campaigns might work for a while, but eventually deliverability will suffer.

The Traditional Way vs. The Smart Way

Traditionally, verifying a domain with Amazon SES involves:

1. Adding the domain in the AWS Console
2. Generating DKIM records
3. Adding TXT records to your DNS
4. Waiting for propagation
5. Going back to AWS to verify
6. Configuring MailWizz to use the verified domain

That’s a lot of back-and-forth between different platforms. And if you’re managing multiple customers or multiple domains, the time adds up fast.

The Verify Sending Domain With Amazon SES for Mailwizz extension solves this by bringing the entire verification workflow directly inside MailWizz. Your customers can add a domain, see the exact DNS records they need, copy them with one click, and verify everything without ever leaving your platform.

Step-by-Step: What the Process Looks Like

Step 1: Add Your Sending Domain

Inside MailWizz, your customer adds a new sending domain. The extension automatically detects whether the domain is associated with an Amazon SES delivery server. No manual configuration is needed — it just works.

Step 2: View the Required DNS Records

This is where most users get confused. DNS records look intimidating if you don’t work with them every day. The extension displays each record in a clean, readable table with the record type, host name, and value clearly separated.

You’ll typically see:

• DKIM records — Usually 3 TXT records generated by Amazon SES
• SPF record — Authorizes Amazon SES to send on your behalf
• DMARC record — Tells receiving servers how to handle unauthenticated emails
• MAIL FROM record — Customizes the return path for bounce handling

Step 3: Copy Records to Your DNS Provider

Each record has a one-click copy button. This is a small detail, but it saves a ton of time when you’re dealing with multiple DKIM records. No more selecting text, worrying about missing a character, or copying the wrong value.

Step 4: Run Verification

Once DNS records are published, the extension checks Amazon SES to see if the domain is verified. If propagation is still happening, the scheduled auto-check feature re-verifies automatically. No need to manually refresh and hope for the best.

Step 5: Start Sending

When the domain shows as verified, your customer can start sending campaigns immediately — with full authentication in place.

What Records Do You Actually Need?

Here’s a quick reference for the DNS records involved:

All four work together to build a complete authentication profile. Missing any one of them can hurt your deliverability.

Common Mistakes to Avoid

Even with a guided workflow, users make mistakes. Here are the most common ones and how the extension helps prevent them:

Wrong record type — Users sometimes add a DKIM record as an A record or CNAME. The extension shows the record type clearly so there’s no confusion.

Missing characters — DKIM values are long strings. One missing character breaks authentication. One-click copying eliminates this risk.

Incomplete setup — Some users only add DKIM and skip SPF or DMARC. The extension displays all required records together so nothing gets missed.

Not waiting for propagation — DNS changes can take minutes or hours. The auto-check feature handles this so users don’t need to guess when propagation is complete.

How This Extension Helps SaaS Owners

If you’re running MailWizz as a SaaS platform for multiple customers, domain verification becomes a support burden. Customers don’t understand DNS. They get stuck. They submit tickets. Your team spends hours explaining the same steps.

The Verify Sending Domain extension changes that by:

• Reducing support tickets — Customers can complete verification on their own
• Shortening onboarding time — New users get verified faster and start sending sooner
• Improving platform reputation — Verified domains mean better deliverability across your entire platform
• Adding sending protection — You can block or warn against sending from unverified domains

Final Thoughts

Domain verification shouldn’t be the hardest part of setting up email sending. With the right tools, it becomes a smooth, guided process that your customers can complete in minutes instead of days.

If you’re using MailWizz with Amazon SES, the Verify Sending Domain With Amazon SES for Mailwizz extension is one of those tools that pays for itself in time saved and headaches avoided.

Give your customers a faster way to verify domains, improve deliverability, and send with confidence.
