1. Keep Emails Plain and Personal
HTML-heavy, image-rich, or template-looking emails often get flagged as promotions or spam.
Best Practice:
Stick to plain text emails (avoid using images in the signatures even for 1st email especially).
Avoid links in first-touch messages.
Limit each email to 50–125 words (ideally under 750 total characters).
Don’t include attachments.
2. Avoid Spam Trigger Words
Certain words signal promotional or suspicious activity to spam filters, we have our spam counting feature, please use that.
Examples to avoid:
“Free,” “100% guarantee,” “Act now,” “Buy now,” “Earn money fast”
3. Use Spintax to Add Variability
Repeated email templates across a campaign increase the risk of getting flagged for low content diversity.
Solution:
Use Spintax (e.g., “Hi {John|there|team}”) or merge tags to create dynamic variations and prevent repetition-based spam triggers.
