Why Your Emails Land in Spam (and the Settings I Checked)

The $0 Mistake That Landed My Emails in Spam

Sometime after I first tried affiliate marketing back in 2014 and made exactly $0, my enthusiasm had fizzled out pretty quickly. But when I decided to give it another go in 2025, with some fresh tools and a bit more experience, I hit another snag: my emails kept landing in spam folders. Not the best way to rebuild momentum.

Understanding Why Emails Get Flagged as Spam

When your emails end up in spam, it’s easy to feel like you’re just not cut out for this. I used to think it meant my message wasn’t interesting enough or that people were unsubscribing en masse. But then I learned about how email providers use algorithms and filters to decide what lands in a user’s inbox versus the dreaded spam folder.

Email services look at various factors like the sender’s reputation, content quality, and recipient engagement to label emails as spam. Even the slightest misstep could result in your emails never seeing the light of day.

The Settings That Fixed My Email Issues

Let’s talk fixes; I’m still testing whether these changes fully fixed it. I’ll update this post when I know.

1. Authenticate Your Domain

This sounds technical, but it’s actually pretty straightforward. Authenticating your domain involves setting up SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records on your domain’s DNS settings. These act like a passport for your emails, verifying you’re the rightful sender.

2. Clean Up Your List

This one was tough because you want every subscriber you can get. But keeping inactive or unengaged subscribers does more harm than good. It tells email providers that people aren’t interested in your content, which can hurt your deliverability rate.

3. Watch Your Content

This might sound obvious, but avoid phrases traditionally linked to spam – words like “free,” “guarantee,” or too many exclamation points can trigger filters. Keeping your content genuine and straightforward helps stay away from those red flags.

Steps You Can Take Today

1. Check Your Authentication: Head over to where you manage your domain and set up SPF and DKIM records if you haven’t already.
2. Purge Inactive Subscribers: Use any email marketing tool to identify subscribers who haven’t engaged with your last few campaigns and remove them.
3. Edit Your Email Content: Go through your next email draft and eliminate any spammy language or excessive punctuation.

The Importance of Monitoring

You’d think fixing these settings would solve everything magically overnight, but unfortunately, things aren’t quite so simple. It’s crucial to keep an eye on metrics like open rates and bounce rates regularly. Make adjustments as needed because this isn’t a one-time fix — it’s an ongoing process.

If you’re struggling with getting those emails out of spam folders and into inboxes where they belong, you’re not alone. Implementing these changes helped me immensely, though it didn’t happen instantly; it took some tweaking along the way.
