How This Checker Works
Spam Trigger Detection: We scan for words and phrases commonly flagged by spam filters like "FREE!!!", "Act now", "Limited time", excessive caps, and more.
Length Analysis: Subject lines between 30-50 characters perform best. Preview text should be 40-130 characters to display fully on most email clients.
Personalization Check: Emails with personalized from names and subject lines see higher open rates. We check for personalization patterns.
Special Character Review: Excessive punctuation, all caps, and certain symbols can trigger spam filters.
Email Deliverability Best Practices
- Use a recognizable from name: Include your name or brand. "Sarah from Wieldr" performs better than just "Wieldr".
- Avoid spam trigger words: Words like "free", "guarantee", "no obligation" in all caps trigger spam filters.
- Keep subject lines concise: 30-50 characters is ideal. Mobile devices truncate longer subjects.
- Write compelling preview text: Don't let email clients pull random content. Craft it intentionally.
- Avoid excessive punctuation: Multiple exclamation marks and question marks look spammy.
- Test with emojis carefully: One emoji can boost open rates, but too many hurt deliverability.
