Check SPF and DKIM Records
The most common cause of emails landing in spam is missing DNS authentication records.
- Go to Settings > Email and check the Domain Health indicator.
- If it shows a warning, you need to add SPF and DKIM records to your domain's DNS settings.
- SPF record: Add a TXT record with the value provided on the settings page (e.g.,
v=spf1 include:sendgrid.net ~all). - DKIM record: Add the CNAME or TXT record as specified by your email provider.
Spam Folder Issues
If recipients find your emails in spam:
- Avoid using ALL CAPS or excessive exclamation marks in subject lines.
- Keep your email content balanced between text and images. Emails with only images are flagged by spam filters.
- Include an unsubscribe link in every broadcast (SteepleOS adds this automatically).
SMTP Connection Errors
If broadcasts fail with a connection error:
- Verify your SMTP credentials under Settings > Email.
- Confirm the SMTP port is correct (typically 587 for TLS or 465 for SSL).
- Some hosts block outbound SMTP. Check with your hosting provider if you are using custom SMTP.
Bounce Management
High bounce rates damage your sender reputation. SteepleOS automatically marks hard-bounced addresses and stops sending to them. Review bounced contacts under Communications > Health > Bounces and update or remove invalid addresses.
