Even with Flowforth’s built-in email best practices, some emails may still land in spam folders. Here’s what to look out for and how you can reduce the risk.

​
What Flowforth Already Handles for You

We automatically include industry-standard protections in every email:
  • Unsubscribe links and email preference management
  • A visible physical address (required by anti-spam laws)
  • Proper email headers including a one-click unsubscribe link
  • Required DNS records:
    • SPF
    • DKIM
These help establish your domain as a trusted sender.

​
1. Missing or Weak DMARC Policy

While DMARC is not required to send emails, we highly recommend setting it up.
  • DMARC works alongside SPF and DKIM to tell email providers how to handle suspicious emails from your domain.
  • Without it, your emails may still pass authentication but be treated as less trustworthy.
Ask your domain administrator to set up a DMARC record for stronger protection and deliverability. You can find our standard recommended DMARC record at https://flowforth.co/settings/domains

​
2. Spammy or Aggressive Content

Certain content can raise red flags for spam filters. Avoid:
  • All caps in subject lines or body (e.g. “ACT NOW!”)
  • Excessive exclamation points (e.g. “Free!!!”)
  • Overuse of salesy or promotional language (e.g. “Buy now”, “100% FREE”)
  • Embedding too many links or call-to-actions
Write like a human. Keep your tone warm, relevant, and clear.

​
3. Poor Text-to-Image Ratio

  • Emails with mostly images and little text are often flagged as spam.
  • Aim for a balanced mix of readable text and images.
Never send an email that is one big image or too many back-to-back images without explanation.

​
4. Sender Name and Email Address

Your sender name and email address matter.
  • Avoid using generic or unclear names (e.g. “Admin” or “Email Team”).
  • Make sure your address sounds legitimate and recognizable (e.g. hello@yourchurch.com, not info123@domain.net).
  • Flowforth already prevents sending from no-reply addresses.

​
5. Low Engagement or Past Complaints

  • If people consistently ignore, delete, or mark your emails as spam, email providers may start flagging your future messages.
  • Avoid emailing people who haven’t engaged in a long time.
  • Clean your lists regularly and respect unsubscribes.

​
6. Sending to Invalid or Old Addresses

  • Sending to outdated or incorrect email addresses increases your bounce rate, which hurts your sender reputation.
  • Make sure your lists are current and accurate.
  • Flowforth automatically suppresses bounced and cleaned addresses.

​
Final Tip: Test Before Sending

  • Send test emails to a few different email clients (Gmail, Outlook, etc.) to see where they land.
  • Avoid adding attachments or excessive formatting in your initial drafts.
