    Common Email Problems and Solutions

    Email problems can range from simple configuration errors to complex deliverability issues. This guide covers the most common problems and provides step-by-step solutions to get your emails sending and delivering successfully.

    Issue 1: Emails Not Sending

    If your campaigns won't send, check these common causes:

    Problem: "Send Failed" Error

    Step 1:Check that your SMTP provider is connected and active
    Step 2:In Settings > Email Configuration, verify provider status shows "Connected"
    Step 3:Test your connection by sending a test email
    Step 4:If test fails, reconnect your provider and re-enter credentials
    Step 5:Check provider limits - you may have exceeded daily sending limit
    Step 6:If using SendGrid free tier, remember 100 emails/day limit

    Problem: "Invalid Recipient" Error

    Step 1:Error usually means one or more recipients have invalid email addresses
    Step 2:In your campaign, click "Validate Recipients"
    Step 3:Lead Fuel CRM will identify invalid addresses
    Step 4:Remove contacts with obvious errors (missing @, typos)
    Step 5:Try sending again to remaining valid addresses

    Problem: Campaign Stuck in "Sending" Status

    Step 1:Sometimes campaigns get stuck if the server encounters an error
    Step 2:Wait 5 minutes - the campaign may complete automatically
    Step 3:Check your SMTP provider's status page for outages
    Step 4:If still stuck after 10 minutes, contact Lead Fuel CRM support
    Step 5:As a temporary fix, you can pause and reschedule the campaign

    Issue 2: Emails Landing in Spam

    If recipients are receiving your emails but they're in spam folders, your sender reputation or content needs improvement:

    Problem: Gmail Spam Folder Placement

    Step 1:Verify SPF, DKIM, and DMARC authentication records are correct
    Step 2:Use Google Postmaster Tools to check your sender reputation
    Step 3:Look for "Not authenticated" warnings in Postmaster Tools
    Step 4:If emails fail authentication, fix your DNS records and wait 24-48 hours
    Step 5:Check your email content for spam trigger words (FREE, BUY NOW, URGENT)
    Step 6:Ensure your unsubscribe link is working and visible
    Step 7:Ask Gmail users to move your emails to Primary folder to train the filter

    Problem: Outlook/Hotmail Spam Issues

    Step 1:Outlook is particularly sensitive to list quality and engagement
    Step 2:Remove unengaged subscribers (no opens in 6+ months)
    Step 3:Lower your sending volume initially and increase gradually
    Step 4:Avoid sending to Outlook addresses on first send of a new domain
    Step 5:Use a gradual warm-up: day 1 = 10 emails, day 2 = 50, day 3 = 100, etc.
    Step 6:Monitor bounce rates - Outlook soft bounces often indicate list quality issues

    Problem: High Spam Score

    Step 1:In campaign review, check your spam score (should be green)
    Step 2:Common trigger: All caps text or excessive punctuation
    Step 3:Remove or minimize URLs - each link adds to spam score
    Step 4:Use professional language and avoid hyperbole
    Step 5:Check image alt text - broken images increase spam score
    Step 6:Ensure email is not 90%+ images (should be at least 40% text)
    Step 7:Use Lead Fuel CRM's "Spam Check" tool to identify issues

    Issue 3: High Bounce Rate

    If you're experiencing high bounce rates (>5%), your list quality is the issue:

    Identifying Bounce Types

    • Hard Bounce: Permanent failure - invalid address, domain doesn't exist. DELETE these contacts.
    • Soft Bounce: Temporary failure - mailbox full, server busy. Usually resolves. Retry later.
    • Block Bounce: Server rejected the email - often due to spam filter or sender reputation
    Step 1:Go to Email > Campaign Analytics > View Bounces
    Step 2:Export the bounce list and analyze the bounce types
    Step 3:Remove all hard bounces (these are permanently invalid)
    Step 4:Retry soft bounces after 24 hours
    Step 5:If bounce rate is still high, your list has quality issues
    Step 6:Implement list cleaning practices going forward

    Issue 4: Poor Deliverability (Low Open Rate)

    If open rates are significantly below industry average, investigate these factors:

    Check 1: Is Email Even Arriving?

    Step 1:Send a test email to yourself and multiple team members
    Step 2:Check inbox and spam/junk folders
    Step 3:If test email is in spam, your authentication or content has issues
    Step 4:If test email is in inbox but campaigns in spam, you may have a list quality issue
    Step 5:Send from different email clients (Gmail, Outlook) to compare

    Check 2: Subject Line and Preview Text

    Step 1:Boring or unclear subject lines result in low open rates
    Step 2:Test different subject line approaches: question, curiosity, urgency, benefit
    Step 3:Include first name personalization ({{FirstName}}) for +5-10% lift
    Step 4:Test optimal send time - most opens occur 10am-2pm business days
    Step 5:Avoid overused words like "Urgent," "Act Now," "Free"

    Check 3: List Engagement

    Step 1:Old, inactive lists have inherently low open rates
    Step 2:Identify contacts with zero opens in last 12 months
    Step 3:Segment them out and don't include in regular campaigns
    Step 4:Run a re-engagement email: "We haven't heard from you in a while..."
    Step 5:Remove contacts that don't re-engage after 2-3 attempts

    Issue 5: Authentication Errors (SPF, DKIM, DMARC)

    Authentication failures are a major cause of deliverability problems:

    Problem: SPF Record Missing or Invalid

    Step 1:Go to Settings > Email > Authentication Records
    Step 2:Copy your SPF record exactly as shown
    Step 3:Log into your domain registrar (GoDaddy, Namecheap, etc.)
    Step 4:Add or update your SPF TXT record
    Step 5:SPF should include all your sending providers
    Step 6:Use online SPF checker (mxtoolbox.com) to validate
    Step 7:Wait 24-48 hours for full propagation

    Important: SPF records should end with "~all" (soft fail) during testing, then change to "-all" (hard fail) in production. Using "-all" immediately may block legitimate emails.

    Problem: DKIM Not Signing

    Step 1:Verify DKIM records are added to your DNS
    Step 2:Check with a DKIM validation tool (mxtoolbox.com/dkim.aspx)
    Step 3:If validation fails, re-add the DKIM record to your DNS
    Step 4:Ensure you've copied the entire key including quotes
    Step 5:Test after 24 hours - DNS propagation takes time

    Problem: DMARC Policy Too Strict

    Step 1:Start with DMARC policy p=none (monitoring only)
    Step 2:Check DMARC reports to see what's failing alignment
    Step 3:Once you're comfortable, move to p=quarantine (jail suspected failures)
    Step 4:Finally use p=reject (hard reject failures) for maximum protection
    Step 5:Align your "From" domain with your sending domain

    Issue 6: Links Not Working or Tracking

    Problem: Links Broken in Email

    Step 1:In campaign review, use the "Link Check" tool
    Step 2:All links should show as "Valid" (green checkmark)
    Step 3:If any show as "Invalid" (red X), fix the URLs
    Step 4:Common issues: missing http://, typos, spaces in URLs
    Step 5:Test each link manually before sending

    Problem: Click Tracking Not Working

    Step 1:Verify click tracking is enabled in campaign settings
    Step 2:Go to Email > Campaign Settings > Tracking
    Step 3:Toggle "Track Link Clicks" to ON
    Step 4:Re-save the campaign and resend test email
    Step 5:Click the link and check if click is recorded

    Issue 7: Unsubscribe Issues

    Problem: Unsubscribe Link Not Working

    Step 1:Verify your footer includes the unsubscribe link
    Step 2:In template, add unsubscribe merge field: {{UnsubscribeLink}}
    Step 3:Test the unsubscribe link - it should show confirmation
    Step 4:Verify contact status changes to "Unsubscribed" after clicking
    Step 5:Check that contact receives a confirmation email

    Problem: Manual Unsubscribe Not Taking Effect

    Step 1:Go to Contacts > Select the contact
    Step 2:Look for "Subscription Status" field
    Step 3:Change status from "Subscribed" to "Unsubscribed"
    Step 4:Save the change
    Step 5:Verify contact no longer receives emails
    Step 6:This should take effect immediately
