Finding Resend Integration​

Step 1: Access Integrations​

  1. In Expedify, go to Settings → Integrations
  2. You'll see tabs at the top: All, Active, Available
  3. Click on Active tab

Step 2: Locate Resend​

  1. In the Active integrations list, find Resend
  2. You'll see it's marked as Managed or Pre-configured
  3. Status will show as Active (green checkmark)
  4. Click on the Resend card to configure

Domain Verification​

Before sending emails, you must verify your domain to prove ownership and improve deliverability.

Why Verify Your Domain?​

✅ Required for Sending: Can't send emails without verified domain ✅ Improves Deliverability: Verified domains land in inbox, not spam ✅ Builds Trust: Recipients see your real domain, not generic sender ✅ Enables DKIM/SPF: Email authentication reduces spam flags

Step 1: Add Your Domain​

  1. Click on Resend integration card (in Active tab)
  2. Click Add Domain or Verify Domain button
  3. Enter your domain:

Options:

  • Full Domain: yourcompany.com
  • Subdomain: mail.yourcompany.com or email.yourcompany.com

Which to choose?

  • Full Domain: If you want to send from name@yourcompany.com
  • Subdomain: If you want to separate email sending from your main domain (recommended for marketing emails)

Example:

  • Main website: acmecorp.com
  • Email subdomain: mail.acmecorp.com
  • Sender address: support@mail.acmecorp.com
  1. Click Add Domain

Step 2: Get DNS Records​

After adding your domain, Expedify will display DNS records you need to add:

Record TypeNameValuePurpose
TXT@ or _resendresend-verify=abc123...Domain ownership verification
TXT@ or _dmarcv=DMARC1; p=none...DMARC policy
CNAMEresend._domainkeyresend._domainkey.resend.comDKIM signature
MX@feedback-smtp.resend.comBounce handling

Important: Copy these records exactly as shown - you'll add them to your domain registrar.

Step 3: Add DNS Records to Your Domain​

Go to your domain registrar (where you bought your domain):

Popular Registrars:

  • GoDaddy
  • Namecheap
  • Google Domains
  • Cloudflare
  • AWS Route 53
  • Domain.com

Steps (general process, varies by registrar):

  1. Log into your domain registrar
  2. Find DNS Management or DNS Settings
  3. Click Add Record for each record type

For TXT Records:

  • Type: TXT
  • Name/Host: Copy from Expedify (e.g., _resend or @)
  • Value: Copy from Expedify (entire string)
  • TTL: 3600 (or default)

For CNAME Records:

  • Type: CNAME
  • Name/Host: resend._domainkey
  • Value: resend._domainkey.resend.com
  • TTL: 3600 (or default)

For MX Records (if shown):

  • Type: MX
  • Name/Host: @
  • Value: feedback-smtp.resend.com
  • Priority: 10
  • TTL: 3600 (or default)
  1. Click Save after adding each record

Step 4: Wait for DNS Propagation​

DNS changes take time to propagate (spread globally):

  • Minimum: 15 minutes
  • Typical: 1-2 hours
  • Maximum: 24-48 hours (rare)

Don't worry if verification fails immediately - this is normal.

Step 5: Verify Domain in Expedify​

After waiting for DNS propagation:

  1. Go back to Expedify → Settings → Integrations → Resend
  2. Find your domain in the list
  3. Click Verify or Check Verification button
  4. If DNS is propagated, you'll see: ✅ Verified
  5. If not yet propagated: ⏳ Pending (wait and try again)

Troubleshooting Verification:

  • Wait longer (DNS can take hours)
  • Double-check DNS records for typos
  • Ensure records are in correct zone (root domain vs subdomain)
  • Use DNS checker tools: dnschecker.org

Adding Sender Email Addresses​

After domain verification, add the email addresses you'll send from.

Why Add Sender Emails?​

  • Workflow Sending: Use in "Send Email" workflow nodes
  • Campaign Sending: Select sender for email campaigns
  • Multiple Senders: Different emails for different purposes (support, sales, marketing)
  • Professional Identity: Recipients see these addresses in their inbox

Step 1: Add Sender Email​

  1. In Resend integration settings, find Sender Emails section
  2. Click Add Sender Email button
  3. Enter email address:

Format: name@verifieddomain.com

Important Rules:

  • ✅ Must use your verified domain
  • ✅ Can add multiple addresses
  • ❌ Can't use unverified domains
  • ❌ Can't use generic domains (gmail.com, yahoo.com, etc.)

Examples (if you verified acmecorp.com):

  • ✅ support@acmecorp.com
  • ✅ sales@acmecorp.com
  • ✅ hello@acmecorp.com
  • ✅ no-reply@acmecorp.com
  • ❌ info@gmail.com (not your domain)

  1. Optionally add Sender Name (what recipients see):

    • Email: support@acmecorp.com
    • Name: "Acme Support Team"
    • Recipients see: "Acme Support Team <support@acmecorp.com>"

  2. Click Add

Step 2: Set Default Sender (Optional)​

  1. From your sender emails list, select one
  2. Click Set as Default
  3. This sender will be pre-selected in workflows and campaigns

Best Practice: Use no-reply@yourdomain.com as default for automated emails

Step 3: Manage Sender Emails​

You can add multiple sender addresses for different purposes:

Email AddressUse CaseSender Name
support@acmecorp.comCustomer support emails"Acme Support"
sales@acmecorp.comSales outreach"Acme Sales Team"
marketing@acmecorp.comMarketing campaigns"Acme Marketing"
hello@acmecorp.comGeneral communications"Acme Corp"
no-reply@acmecorp.comAutomated notifications"Acme Notifications"

Edit or Remove:

  • Click on sender email to edit name

Best Practices​

Domain Setup​

Do:

  • ✅ Use subdomain for marketing emails (mail.yourcompany.com)
  • ✅ Keep main domain for transactional emails
  • ✅ Verify domain before launching campaigns
  • ✅ Wait full 24 hours for DNS propagation if having issues
  • ✅ Add all DNS records (TXT, CNAME, MX)

Don't:

  • ❌ Skip domain verification (emails won't send)
  • ❌ Use generic domains (gmail.com, yahoo.com)
  • ❌ Share verification records publicly

Sender Email Strategy​

Transactional Emails (order confirmations, password resets):

  • Use: no-reply@yourcompany.com or support@yourcompany.com
  • Name: "Your Company Name"
  • These should come from verified main domain

Marketing Emails (newsletters, promotions):

  • Use: marketing@mail.yourcompany.com or hello@mail.yourcompany.com
  • Name: "Your Company Team" or specific team name
  • Use subdomain to separate from transactional

Support Emails:

  • Use: support@yourcompany.com
  • Name: "Customer Support"
  • Allow replies (don't use no-reply@)

Email Content​

High Deliverability:

  • ✅ Write clear, relevant subject lines (avoid spam words)
  • ✅ Include physical address in footer (legal requirement)
  • ✅ Add unsubscribe link for marketing emails
  • ✅ Personalize with recipient's name
  • ✅ Keep HTML clean and simple
  • ✅ Test emails before sending to full list

Avoid Spam Filters:

  • ❌ ALL CAPS SUBJECT LINES
  • ❌ Excessive exclamation marks!!!
  • ❌ Spam trigger words: "FREE", "ACT NOW", "CLICK HERE"
  • ❌ Large images without text
  • ❌ Misleading subject lines

Sending Limits​

Warm-Up Period:

  • Start with small batches (100-200 emails/day)
  • Gradually increase over 2-4 weeks
  • Monitors engagement (opens, clicks)
  • Avoid sudden spikes (sends spam signals)

Daily Limits (approximate):

  • New domain: 100-500 emails/day
  • Warmed domain: 1,000-10,000 emails/day
  • Established domain: 50,000+ emails/day

Resend enforces limits to protect deliverability. If you need higher limits, contact Expedify support.

Troubleshooting​

Domain Verification Failing​

Issue: "Domain verification failed" or stuck on "Pending"

Solutions:

  1. Wait longer: DNS can take 24-48 hours to propagate
  2. Check DNS records:
    • Use dnschecker.org
    • Verify records show globally
    • Check for typos in record values
  3. Correct zone: Ensure records added to correct domain/subdomain
  4. Contact registrar: Some registrars have special DNS setup
  5. Try again: Click "Verify" button after waiting

Common Issues:

  • Added records to wrong domain (root vs subdomain)
  • Extra spaces in TXT record value
  • Using @ instead of subdomain name (or vice versa)
  • DNS not saved properly at registrar

Emails Not Sending​

Issue: Emails fail to send or stuck in queue

Solutions:

  1. Domain verified? Check domain has green ✅ status
  2. Sender added? Ensure sender email is in verified senders list
  3. Correct format? From address must match verified domain
  4. Account limits? May have hit sending limit (check usage)
  5. Check logs: View email logs for error messages

Emails Going to Spam​

Issue: Emails land in spam folder instead of inbox

Solutions:

  1. Verify all DNS records: Especially DKIM and DMARC
  2. Warm up domain: Start with small volumes
  3. Check content: Avoid spam trigger words
  4. Add unsubscribe: Always include for marketing
  5. Monitor engagement: Low open rates hurt reputation
  6. Physical address: Include business address in footer

Sender Email Can't Be Added​

Issue: "Domain not verified" when adding sender

Solutions:

  1. Verify domain first (must have ✅ status)
  2. Ensure sender email uses verified domain
  3. Wait for DNS propagation to complete
  4. Check spelling (sender must match domain exactly)

Bounces and Invalid Emails​

Issue: High bounce rate

Solutions:

  1. Clean email list: Remove invalid addresses
  2. Double opt-in: Verify emails before adding to list
  3. Check typos: Common: gmial.com instead of gmail.com
  4. Monitor bounces: Auto-remove hard bounces
  5. Engagement: Remove contacts who never open (6+ months)

Email Deliverability Tips​

Maintain Good Sender Reputation​

Do:

  • ✅ Send to engaged subscribers only
  • ✅ Remove hard bounces immediately
  • ✅ Honor unsubscribe requests instantly
  • ✅ Send consistent volumes (no sudden spikes)
  • ✅ Monitor spam complaints (keep under 0.1%)
  • ✅ Segment lists (send relevant content)

Don't:

  • ❌ Buy email lists (spam traps guaranteed)
  • ❌ Send to contacts who haven't engaged in 12+ months
  • ❌ Ignore bounces and complaints
  • ❌ Send from newly-verified domain at high volume
  • ❌ Use deceptive subject lines

Email Authentication​

Resend automatically configures:

  • SPF: Sender Policy Framework (who can send)
  • DKIM: DomainKeys Identified Mail (email signature)
  • DMARC: Domain-based Message Authentication (policy)

These improve deliverability by 40%+ by proving emails are legitimate.

Monitor Metrics​

Healthy Email Metrics:

  • Delivery Rate: over 98%
  • Open Rate: 20-30% (varies by industry)
  • Click Rate: 2-5%
  • Bounce Rate: under 2%
  • Spam Complaint Rate: under 0.1%
  • Unsubscribe Rate: under 0.5%

Red Flags:

  • Bounce rate over 5%: List quality issue
  • Spam rate over 0.5%: Content or frequency issue
  • Open rate under 10%: Subject lines or sender reputation
