Why Constant Contact emails go to junk (and how to fix it)
The most common setup gap is skipping Constant Contact’s “self-authentication” step. Until you do it, Constant Contact sends your email from a shared address that ends in ccsend.com instead of your own. Gmail, Yahoo and Microsoft now expect your own domain on bulk email, so those emails are more likely to land in junk. The fix is in Settings, under Advanced settings. It’s free in Constant Contact and takes a day or two to switch on.
Check your own email first. Free, about 90 seconds. You get a grade and a plain-English list of what's working and what isn't.
Check if this is you (1 minute)
- Send yourself a test email from Constant Contact to a personal Gmail address.
- Open it and click the small arrow under the sender’s name.
- Look at the address it came from. If you see ccsend.com anywhere in it, you haven’t self-authenticated yet. Replies still come to you, which is why most people never notice.
A real example
Hank owns a hardware store and emails a weekly deals list from hank@millerhardware.com. When customers open it, the sender address shows a long ccsend.com address instead of his. Gmail sees bulk email that isn’t from his own domain, and more of it goes to junk each month. Hank self-authenticates his domain. Two days later his emails go out from his own address again.
Set up self-authentication
- Log in to Constant Contact, click your name in the top right and choose Settings.
- Open the Advanced settings tab and click Add self-authentication.
- Pick the option with CNAME records (the first one) and click Continue. Choose your domain and click Continue again.
- Click Copy information and send it to whoever looks after your website. They add those lines where your domain is managed (often GoDaddy, Cloudflare, Squarespace, Wix or your web host).
- Wait a day or two, then go back to the same page and click Check status. When it’s ready, click Activate.
Set up and still going to junk?
Then it’s usually what you send or who you send it to:
- Old or bought lists. People who never signed up mark email as spam, and every report hurts. Remove anyone who hasn’t opened anything in a long time.
- Sending from your everyday mailbox too. Big sends from Outlook or Gmail hurt your normal email. The newsletter guide explains why.
- Your other tools. Your invoicing app or website form may still be sending without your domain’s name on it, which drags everything down. See the guide to tools that don’t send as you.
What this guide can’t do for you
It covers the common causes. It can’t tell you which of your tools is the one that’s failing, or give you the exact settings for your business and the company that manages your domain. That’s what the Email Fix does. We check every tool that sends email for you and give you steps written for your setup. If we can't find what's wrong with your email settings, you get your $299 back. The guarantee covers your email settings. No settings can fix email sent to people who didn't ask for it, like bought lists or mass emails.

Common questions
Will I still get replies if my email shows ccsend.com?
Yes. Constant Contact only changes the From address. Your Reply-to address stays yours, so replies still reach you.
Does self-authentication cost anything?
Constant Contact doesn't charge for it. The company that manages your domain may charge if you ask them to add the settings for you.
How long does self-authentication take?
Constant Contact says to check back 24 to 48 hours after the settings are added, then click Check status and Activate.
Can I send from a Gmail or Yahoo address?
You can, but Constant Contact will send it from a shared ccsend.com address because free addresses can't be authenticated. An address at your own business domain works better.
For your IT person or web developer
You can forward this page as it is. Everything below is written so someone who doesn't work with email settings every day can follow it.
1. Check the existing DMARC record first
Look up _dmarc.yourdomain.com. If a v=DMARC1 record exists, keep it and skip Constant Contact's DMARC record: two records at the same name make receivers ignore DMARC (RFC 7489 §6.6.3).
2. Publish the DKIM records
In Constant Contact: profile name → Settings → Advanced settings → Add self-authentication → Self-authenticate using DKIM CNAME records → choose the domain → Copy information. Publish each CNAME exactly as given. Use the DKIM TXT option only if the same domain is authenticated in more than one Constant Contact account. With TXT, sends fail between generating the key and DNS updating, so have the record ready to publish before you generate it.
3. Activate
After 24–48 hours, Check status → Activate. One authenticated domain per account; From addresses must then be on that domain.
4. Check it worked
Send a test to Gmail. The From should be the business's address with no ccsend.com rewrite, and Show original should read DKIM: PASS and DMARC: PASS.
