Domains
A Domain in OptiPub represents a fully qualified domain name (FQDN) used to send email, host websites, or serve campaign links. Every domain must be verified before it can be used.
Navigate to Administration > Domains
Only users in the Administrators group can create and manage domains.
Domains Table
The domains list shows all domains in your account with their verification and authentication status. Available columns:
| Column | Description |
|---|---|
| ID | Unique identifier |
| Domain | The fully qualified domain name |
| Bounce Domain | The domain used for bounce handling |
| List-Unsubscribe Domain | The domain used for list-unsubscribe headers |
| Tracking Domain | The domain used for click tracking |
| Aliases | Domain aliases, with the primary alias highlighted |
| Verified Ownership | Whether OptiPub has verified you own this domain (via TXT record) |
| Ready to Send | Whether the domain is fully configured for sending email |
| SPF | Whether a valid SPF record is detected |
| DMARC | Whether a valid DMARC record is detected |
| Record | The TXT verification record to add to your DNS (hidden by default — enable via table settings) |
| Google Reputation Last 7 Days | A sparkline showing Gmail Postmaster reputation over the past week |
Creating a Domain
- Click Create.
- Enter the Domain Name — the full FQDN including subdomain, root domain, and TLD (e.g.
e.example.com). - Click Save.
An FQDN (fully qualified domain name) is the complete domain address including the subdomain, root domain, and top-level domain. Do not include a scheme/protocol (
https://) or path.
After creation, OptiPub generates a TXT verification record and begins checking DNS automatically. Additional fields become available when editing the domain.
Domain Verification
OptiPub uses a DNS TXT record to verify you own the domain. The TXT record value is generated automatically when you create the domain.
- Open the domain in OptiPub and copy the Record value (formatted as
optipub=xxxxx). - Add a TXT record to your DNS provider:
| Field | Value |
|---|---|
| Name | The subdomain portion of your FQDN |
| Value | The optipub=... record from OptiPub |
| TTL | 86400 (recommended) |
OptiPub checks for the TXT record automatically after domain creation at increasing intervals. Once found, the Verified Ownership column shows a green checkmark. If verification hasn't completed after an hour, review your DNS records and contact support.
Editing a Domain
Click the action menu on a domain row and select Edit to access the full settings. These fields are only available after creation.
Email Domains
| Field | Description |
|---|---|
| Bounce Domain | The domain that handles bounced emails |
| List-Unsubscribe Domain | The domain used in list-unsubscribe email headers |
| Tracking Domain | The domain used for click tracking links in emails |
Aliases
Aliases allow a single domain to respond to multiple hostnames. Add as many aliases as needed and designate one as the Primary Alias.
Selectors
Selectors configure DKIM and BIMI DNS records for the domain. Each selector has:
| Field | Required | Description |
|---|---|---|
| Type | Yes | DKIM or BIMI |
| Selector | Yes | The selector name used in the DNS record lookup |
OptiPub automatically validates selector records:
- DKIM records are checked at
{selector}._domainkey.{domain}for a valid DKIM1 TXT record - BIMI records are checked at
{selector}._bimi.{domain}for a valid BIMI1 TXT record with a logo URL
Tracking Tags
| Field | Description |
|---|---|
| Website Tags | HTML/JavaScript automatically injected into the <head> of all websites and landing pages hosted under this domain (e.g. Google Tag Manager, analytics scripts) |
| Email Tags | HTML automatically injected into the <body> of all email messages sent from this domain |
Domain Detail Page
Click View on a domain to open the detail page. The header displays four status indicators:
- Verified Ownership — domain TXT record verified
- Ready to Send — domain fully configured for email sending
- SPF — valid SPF record detected
- DMARC — valid DMARC record detected
The detail page also shows:
- Domain overview — primary domain, bounce domain, list-unsubscribe domain, and tracking domain
- Aliases — all configured aliases with the primary alias highlighted
- Google Postmaster Tools — Gmail Postmaster data including SPF, DKIM, and DMARC success rates and IP reputation (when available)
- SPF Record — the detected SPF record and DNS lookup count
- DMARC Record — the detected DMARC record and policy
Email Sending Domains
To send email through OptiPub, you must delegate DNS management of a subdomain to OptiPub. OptiPub will manage all DNS records (DKIM, SPF, DMARC, etc.) for the delegated subdomain to ensure correct configuration for email delivery.

Custom Campaign Link Domains
You can use a domain you own to host OptiPub campaign links (landing pages and external URL redirects) instead of using the default OptiPub domain. This provides brand recognition and a professional appearance for your links.
For a full setup guide, see Configure a Custom Domain for Campaign Links.
