Avoiding Spam Flags: Best Practices for Sending Email Campaigns

When sending email campaigns through through your CRM, it’s crucial to send in batches rather than blasting your entire list at once. Sending one large campaign all at once increases the risk of being flagged as spam, which can hurt your deliverability and even get your domain blacklisted.

Send in Batches!

Prevents Spam Triggers – Email providers monitor sudden spikes in outgoing emails. A mass send can trigger spam filters, leading to poor inbox placement.
Improves Deliverability – Sending in smaller batches helps maintain a good sender reputation, ensuring more emails reach inboxes instead of spam folders.
Allows for Monitoring & Adjustments – By sending in waves, you can track open rates, bounce rates, and spam complaints before completing the full campaign.

Best Practices for Sending Email Campaigns

✔ Break your list into smaller segments (e.g., 200-500 or less emails at a time).

✔ Schedule emails in waves over several hours or days rather than all at once.

✔ Warm up new domains by gradually increasing send volume over time.

✔ Use personalized content and avoid spammy words in your subject title (e.g., “free,” “guaranteed,” “limited time”).

✔ Monitor bounce and complaint rates to adjust your strategy if needed.

By following these practices, you’ll protect your sender reputation, improve deliverability, and increase engagement rates with your email campaigns.
