Why Do Cold Emails Go to Spam?
If you're running outbound campaigns, there's nothing more frustrating than your carefully crafted messages landing in the spam folder. Understanding the technical and behavioral reasons behind this is the first step to achieving high deliverability.
1. Technical Setup (SPF, DKIM, DMARC)
Email providers like Google and Outlook use these records to verify that you are who you say you are. If they aren't set up correctly, your emails are flagged almost immediately.
- SPF: Authorizes specific IP addresses to send on behalf of your domain.
- DKIM: Adds a digital signature to your emails, proving they weren't tampered with.
- DMARC: Tells the receiving server what to do if SPF or DKIM fails.
2. Lack of Email Warmup
Sending 100 emails from a brand-new domain is a major red flag for spam filters. You need to "warm up" your inbox by slowly increasing sending volume and getting positive engagements.
Pro Tip: LeadGenHub includes built-in automated email warmup to handle this for you automatically.
3. Poor Content & Spam Triggers
Certain words and formatting choices act as "spam triggers" for modern filters. Avoid these common mistakes:
- Excessive use of CAPS LOCK
- Words like "FREE", "BUY NOW", "WIN"
- Too many links or large images
- Broken HTML or poor formatting
