Are your campaigns landing in spam? The cause is rarely Mailpro — it is almost always a mix of technical setup and content choices. Here is the full checklist.
Important: even a single misconfigured email can hurt your sender score for weeks. Set things up right before your first send.
1. Authentication (SPF / DKIM / DMARC)
- SPF — authorises Mailpro to send for your domain
- DKIM — cryptographic signature
- DMARC — protects against spoofing
2. Sender address
- Use a professional domain (not Gmail/Hotmail)
- Clear, recognisable sender name
- Avoid "noreply@" — prefer a repliable address
3. Email content
| Avoid | Do |
|---|---|
| ALL CAPS, !!!, $$$ | Natural copy |
| 100% image, 0 text | 60% text minimum |
| Spam words (free, urgent…) | Relevant vocabulary |
| Shortened links (bit.ly) | Direct links |
4. List quality
- Double opt-in on new signups
- Regular cleaning (bounces, inactives)
- No bought or rented lists
- Clear, working unsubscribe link
5. Frequency and volume
- Avoid spikes from a cold IP
- Keep a steady cadence
- Watch your complaint rate (< 0.1%)
