If your team is still sending emails from gmail.com or outlook.com addresses, you are leaving credibility on the table. A custom domain email like hello [at] yourcompany [dot] com tells every customer, partner, and investor that you are a real business.
This guide walks you through exactly how custom domain email works, what DNS records you need, and how NoHeck makes the entire process dramatically simpler than the alternatives.
Why Custom Domain Email Matters
First impressions are formed in milliseconds. An email from sarah [at] yourcompany [dot] com carries more weight than sarah.yourcompany [at] gmail [dot] com — and not just psychologically. Custom domain email also gives you:
- Brand consistency — Every email reinforces your company name
- Team control — Create and revoke addresses as people join or leave
- Deliverability — Properly authenticated domains land in inboxes, not spam folders
- Compliance — Meet business requirements that demand branded communication
For startups pitching investors, agencies sending proposals, or operations teams coordinating with vendors, custom email is not optional — it is foundational.
The DNS Records You Need
Setting up custom domain email requires three key DNS records. Here is what each one does:
MX Records (Mail Exchange) — These tell the internet where to deliver mail for your domain. Without MX records, emails sent to yourdomain [dot] com addresses have nowhere to go. You will add one or two MX records pointing to your email provider's servers.
SPF (Sender Policy Framework) — A TXT record that lists which servers are authorized to send email on behalf of your domain. This prevents spammers from spoofing your address. Without SPF, your emails are more likely to land in spam.
DKIM (DomainKeys Identified Mail) — A cryptographic signature attached to every outgoing email that proves the message was not altered in transit. DKIM uses a public/private key pair — the public key lives in your DNS, and the private key signs each message on the server side.
Optionally, you should also set up DMARC — a policy record that tells receiving servers what to do when SPF or DKIM checks fail (quarantine, reject, or do nothing).
The Google Workspace Way (Manual Setup)
With Google Workspace, setting up custom domain email looks like this:
- Sign up for Google Workspace ($7/user/month minimum)
- Verify domain ownership via a TXT record
- Manually add MX records (5 separate records with different priorities)
- Manually generate and add a DKIM TXT record from the admin console
- Manually create an SPF TXT record
- Wait up to 48 hours for DNS propagation
- Manually provision each user mailbox from the admin panel
For a technical founder, this is manageable. For a non-technical team lead, this is a weekend project that often goes wrong.
The NoHeck Way (Automated Setup)
NoHeck takes a fundamentally different approach to custom domain email:
- Add your domain — Enter your domain name in Workspace Settings
- Verify ownership — NoHeck generates a single TXT record for you to add
- Automatic DKIM — NoHeck generates RSA-2048 DKIM keys and publishes the DNS record automatically. No manual key generation, no copying Base64 strings
- Automatic SPF — NoHeck configures SPF alignment as part of the setup
- Mailbox provisioning — Create mailboxes directly from your workspace. No separate admin console
The entire process takes under 10 minutes for most domains. DNS propagation still depends on your registrar, but the configuration itself is handled for you.
What About Deliverability?
Email deliverability depends on authentication (SPF, DKIM, DMARC), sender reputation, and content quality. NoHeck handles authentication automatically with RSA-2048 DKIM signing — the same standard used by Google and Microsoft. Your emails are cryptographically signed from day one.
We use Amazon SES as our sending infrastructure, which maintains high deliverability rates and handles IP reputation management at scale.
Pricing Comparison
| Provider | Cost | What you get |
|---|---|---|
| Google Workspace Starter | $7/user/mo | Email + 30GB storage per user |
| Microsoft 365 Basic | $6/user/mo | Email + 50GB storage per user |
| NoHeck Free | $0/mo | Messaging for up to 5 users; mailboxes add-on $4/ea |
| NoHeck Startup | $12/user/mo | Messaging + email add-on $4/ea, unlimited members |
| NoHeck Business | $30/user/mo | Everything + unlimited domains, advanced admin, unlimited members |
For small teams, NoHeck is significantly cheaper — messaging is free for up to 5 users, and you only pay $4/mailbox/month for the email accounts you actually need.
Getting Started
If you are ready to set up custom domain email for your team, here is the shortest path:
- Create a free NoHeck workspace (messaging is free, no credit card)
- Add your custom domain (1 domain included even on Free)
- Create mailboxes as an add-on ($4/mailbox/month)
- Upgrade to Startup ($12/user/mo) when your team grows past 5 users
Custom domain email is available on every plan as an add-on — you only pay for the mailboxes you create.
