If you’re sending email campaigns from your website and wondering why your open rates are low, the answer may not be your subject lines.
It’s your email reputation.
Most website owners don’t realize that sending cold emails—or even newsletters—without proper setup can get your domain flagged as spam. And once it’s damaged, it’s hard to recover.
Here’s how to stop that from happening and start landing in real inboxes.
✅ Step 1: Warm Up Your Domain the Right Way
Imagine walking into a gym and trying to lift 200 kilos on your first day. That’s what sending 500+ emails from a brand-new domain looks like to Google.
Instead, you need to gradually build trust with mailbox providers like Gmail, Outlook, and Yahoo.
That’s called email warm-up.
We automatically send small batches of personalized emails from your domain—then slowly increase the volume—until inbox providers trust your domain as legitimate. This process mimics natural behavior and establishes your sender reputation safely.
Benefits of a proper warm-up:
Avoid spam folders
Improve open & reply rates
Build long-term email credibility
🔐 Step 2: Authenticate Your Emails with SPF, DKIM, and DMARC
Even if you’re using a trusted email platform, your emails can still look suspicious without proper authentication.
That’s where these three tools come in:
✳️ SPF (Sender Policy Framework)
Tells email providers which servers are allowed to send emails on your behalf. Without SPF, anyone can spoof your domain.
✳️ DKIM (DomainKeys Identified Mail)
Adds a digital signature to your messages, verifying that they haven’t been tampered with during delivery.
✳️ DMARC (Domain-based Message Authentication, Reporting, and Conformance)
Acts as your domain’s email policy. It tells providers what to do if SPF or DKIM fails—and sends reports on any suspicious activity.
When these are all aligned correctly, your domain becomes trusted and protected.
📉 What Happens If You Skip These Steps?
Your emails land in spam or get blocked entirely
Your domain can be blacklisted
You lose leads and credibility
Your future campaigns perform worse—even if your content is great
