Setting Up Email Navigate to Settings → Channels and click Configure next to Email.
Configure your sender details:
Field Description Example Sender Name Name shown in inbox ”Sarah from Acme” Sender Email From address ”hello@acme.com ” Reply-To Where replies go ”support@acme.com ”
Use a recognizable sender name. “Sarah from Acme” performs better than generic “Acme Marketing Team”.
Step 2: Domain Verification Verify your sending domain to improve deliverability:
Add Your Domain
Enter your sending domain (e.g., acme.com)
Get DNS Records
RevBridge provides DNS records to add
Add Records to DNS
Add the records via your domain registrar

Required DNS Records Record Type Purpose SPF Authorizes sending servers DKIM Cryptographic signature for authenticity DMARC Policy for handling failures MX Return path for bounces
# SPF Record (TXT) v=spf1 include:_spf.revbridge.ai ~all # DKIM Record (TXT) revbridge._domainkey.yourdomain.com v=DKIM1; k=rsa; p=MIGfMA0GCSqG... # DMARC Record (TXT) _dmarc.yourdomain.com v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com
DNS changes can take up to 48 hours to propagate. Plan ahead when setting up email.
Step 3: Send Test Email After verification:
Click Send Test
Enter your email address
Check your inbox
Verify email renders correctly
Email Best Practices Subject Lines Do Don’t Keep under 50 characters Write long subject lines Create curiosity or urgency Use ALL CAPS Personalize when possible Use spam trigger words A/B test variations Mislead about content
Examples :
✅ “Sarah, your cart is waiting”
✅ “24 hours left: 20% off everything”
❌ “FREE!!! CLICK NOW!!! LIMITED TIME!!!”
Preview Text The preview text appears after the subject in many email clients:
Keep it under 100 characters
Complement (don’t repeat) the subject line
Include a call to action
Email Design Above the fold (visible without scrolling):
Logo
Main headline
Primary CTA
Key message
Structure :
Single column for mobile compatibility
Clear visual hierarchy
Adequate white space
Scannable content with headers
Images Guideline Reason Include alt text Images may be blocked Optimize file size Faster loading Use hosted images Better tracking Don’t rely solely on images Some clients block by default
Call to Action
Make buttons large and tappable (44px minimum)
Use contrasting colors
Action-oriented text (“Shop Now” not “Click Here”)
One primary CTA per email
