Verify Your Domain

Add your sending domain and DNS records so Brew can send emails on your behalf

Your domain identifies you in the digital world. To send emails with Brew, you need to complete a one-time verification process that takes about five minutes. Once verified, every email you send through Brew comes from your own domain.

How to Verify Your Domain

1. Add your sending domain

   Go to Settings → Domains and click Add sending domain. Enter the domain you want to send from.

   We strongly recommend using a subdomain rather than your root domain. For example, use updates.revolut.com instead of revolut.com.

   If you use a root domain and run into deliverability problems, every sending stream on that domain can be affected. Isolating email on a subdomain means issues only impact that subdomain - your broader reputation stays intact.

   Good subdomain options:

   • mail.yourdomain.com
   • updates.yourdomain.com
   • news.yourdomain.com

   When ready, click Add Domain to start verification.

2. Set default sender settings

   Next, configure how your emails appear in recipients’ inboxes. Brew automatically extracts this information from your domain during sign-up, but you should verify it’s correct.

   • Sender name - appears alongside your email address. We suggest keeping it simple and personal (e.g. a real name). You can change this per email in the editor.
   • From email - the email address that appears in the “From” field of your emails.
   • Reply-to email - where replies are sent. Use a real, monitored address (never “no-reply”). Replies signal to email providers that your content is valuable.

   You can change these when sending each email.

3. Add DNS records

   Authorize Brew to send on your behalf by adding DNS records. This works because anyone can read DNS records, but only the domain owner can add them - so adding Brew’s records proves you own the domain.

   Zone File (Fastest)

   Download the zone file as a .txt file from the Brew dashboard, then upload it to your domain registrar. This adds all the DNS records in a few clicks.

   Manual Setup

   Add each record individually by copying the values from Brew and pasting them into your domain registrar’s DNS settings.

   For each record:

   1. Find the DNS section for your domain in your registrar
   2. Add a new record and select the correct type (TXT, MX, or CNAME)
   3. Copy the Name and Value from the Brew dashboard and paste them into the corresponding fields

   Always use the Copy button in Brew. Long values may not display fully in the input field, so dragging to select can miss characters.

   Some providers label the value field as “Content” instead of “Value.” You can leave TTL at your provider’s default.

   Records you’ll add

   DKIM (required)

   A cryptographic key that inboxes check to confirm a message wasn’t altered in transit. You’ll add this as a TXT record.

   SPF (required)

   When a mailbox receives an email claiming to be from your domain, it checks your SPF record to see which servers are authorized to send for you. You’ll add both an MX and a TXT record.

   DMARC (optional but recommended)

   Check whether your domain already has a DMARC record - some platforms add one automatically. If a DMARC record exists in any form, you’re good. If it’s missing, copy and paste the values Brew provides.

   Provider-specific instructions

   Not sure how to add DNS records at your registrar? Expand below for guidance.

   GoDaddy - Log in, open your domain’s DNS settings, click Add, and create each record. For MX records, set priority to 10. If you see an “invalid hostname” error, try adding a period (.) at the end of the value. GoDaddy help

   Cloudflare - Log in, select your domain, go to DNS, click Add record. Set proxy status to “DNS Only” (gray cloud) for all records - proxying breaks email authentication. Cloudflare help

   Google Domains - Log in, select your domain, go to DNS, and use the Custom resource records area. Google may add quotes to TXT records - this is normal. Google help

   Namecheap - Log in, go to Advanced DNS. If you use Gmail/G Suite, switch Mail Settings to Custom MX before adding Brew’s MX records, then re-add Gmail’s MX record. Namecheap help

   AWS Route 53 - Log in, select your hosted zone, click Create record. For MX records, put priority and value together. Only enter the subdomain part for record names. AWS help

   Squarespace - Log in, go to Domains, pick your domain, scroll to Custom Records. Remove trailing periods if you see errors. Squarespace help

   Vercel - Log in, open your domain’s DNS settings. Use only the subdomain part for record names. Vercel help

   Wix - Wix DNS doesn’t support MX records for subdomains if nameservers point to Wix. Use the “Pointing” method or manage DNS externally (e.g. Cloudflare). Wix help

   Dreamhost - Currently unsupported for custom subdomain MX records. Use an external DNS provider or contact Dreamhost support. Dreamhost help

   Don't have access to your domain registrar?

   If you don’t have direct access to your domain registrar:

   1. Add technical team members to your Brew account who can handle the DNS setup
   2. Share this guide with your IT team or domain administrator
   3. They’ll have all the instructions needed to add the required DNS records

   MX record conflicts

   If you already have an MX record for the same hostname (e.g. mail.yourdomain.com), remove it before adding Brew’s MX record.

   The MX record is for your sending subdomain, not your root domain, so it won’t affect any existing email setup on your root domain.

   If you need to keep your existing MX record, use a different subdomain for Brew (e.g. newsletter.yourdomain.com), update your sending domain in Settings, and follow these steps again.

   Not sure who hosts your DNS? Use whois.domaintools.com to look up your domain’s nameservers and find your DNS provider.

4. Verify your records

   Return to the Brew dashboard and click Verify records. As each record is confirmed, it turns green in the UI. When every record is verified, the tag next to your domain turns green - your domain is ready for sending.

   DNS propagation can take up to 72 hours. If verification doesn’t happen immediately, check back later - this is normal.

Best Practices

Use a subdomain (recommended)

Sending from a subdomain like mail.yourdomain.com instead of your root domain protects your main domain’s reputation. If deliverability issues occur on a subdomain, you can isolate the problem without affecting your broader domain reputation.

The subdomain you choose appears in the “From” field of all your emails, so pick something recognizable and professional.

Use a real reply address (never no-reply)

Use addresses like [e-mail] or [e-mail] and make sure someone monitors replies. When recipients reply to your emails, it signals to email providers that your content is valuable - helping your deliverability.

Align links with your sending domain

When your email links point to the same domain you’re sending from, it builds trust and avoids spam filters. Avoid link shorteners like bit.ly in marketing emails.

FAQ

Can I change my sending domain later?

Yes. Go to Settings → Domains and update your domain at any time. You’ll need to complete the verification process again for the new domain, and we recommend warming up the new domain as well.

Why does it say my domain is already in use?

Another Brew account has already verified this domain or a related domain. Once verified, a domain and all its subdomains are protected.

What to do:

• Contact your team to find who set up the original Brew account
• Ask the domain owner to invite you as a team member
• If there’s an error, contact [e-mail] with proof of domain ownership

What if I don't own a domain?

Purchase one through a registrar like GoDaddy, Namecheap, or Google Domains.

When do I need to repeat this process?

You’ll need to verify again if you switch subdomains, change your root domain, switch DNS providers, or change your domain’s nameservers.
