Why Your Author Newsletter Is Going to Spam — And How to Get Back in the Inbox
You spent hours writing your newsletter. Your readers never saw it. Here's why emails from author newsletters land in spam folders — and the specific steps to fix it, in plain English.
Difficulty: Intermediate
Time to Fix: Technical fixes: 30–60 minutes. List health improvements: ongoing.
Platforms Affected: MailerLite, Kit (formerly ConvertKit), Mailchimp, and all major author email platforms
Best For: Authors whose newsletter open rates have dropped sharply, who have had subscribers tell them they're not receiving emails, or who want to protect their sender reputation before a problem occurs.
Why Emails Go to Spam — The Fundamentals
Every email you send is evaluated by the receiving email provider (Gmail, Outlook, Yahoo) against a set of signals that determine whether it goes to the inbox, the promotions tab, or spam. These signals fall into three categories: technical authentication, sender reputation, and content quality.
The good news is that all three are within your control. The bad news is that if your sender reputation degrades significantly, rebuilding it takes time — prevention is genuinely much easier than recovery.
Fix #1: Set Up Your Technical Authentication (The Unsexy but Critical Step)
Email authentication tells inbox providers that your emails are genuinely from you and not spoofed. Most authors skip this because it sounds technical — but your email platform makes it straightforward, and skipping it is one of the biggest deliverability mistakes you can make.
The three records you need: SPF, DKIM, and DMARC
These are three small text entries you add to your domain's DNS settings (usually through your domain registrar — wherever you bought your domain name, like Namecheap, GoDaddy, or Squarespace). Your email platform (MailerLite, Kit, Mailchimp) will give you the exact values to copy and paste. You don't need to understand what they mean — you just need to add them.
• Log into your email marketing platform and find the 'Domains' or 'Sender Authentication' section
• Your platform will show you three records to add to your domain DNS settings
• Log into your domain registrar and find 'DNS Management' or 'DNS Records'
• Add each record exactly as shown — don't modify the values
• Return to your email platform and click 'Verify' — it typically takes 24–48 hours to propagate
⚠️ WARNING: Since early 2024, Gmail and Yahoo require DMARC authentication for bulk senders. If you're sending to more than 5,000 subscribers and haven't set up these records, a significant portion of your emails are going to spam or being rejected entirely.
Fix #2: Clean Your List
A list full of inactive subscribers is one of the fastest paths to the spam folder. If 40% of your subscribers haven't opened an email in six months, inbox providers interpret this as evidence that your content isn't wanted — and they start routing new emails to spam preemptively.
The re-engagement campaign
Before removing inactive subscribers, send a specific re-engagement email to anyone who hasn't opened in 90–180 days. Subject line: 'Still want to hear from me?' Body: short, direct, one click to confirm they want to stay. Anyone who doesn't respond in two weeks gets removed. This is not a failure — it's list health maintenance.
The hard bounce list
Email addresses that bounce hard (permanent delivery failure — the email address doesn't exist) need to be removed immediately. Most email platforms do this automatically, but verify that your platform's auto-remove setting is enabled.
💡 TIP: A smaller, engaged list of 3,000 active subscribers who open your emails will consistently outperform a list of 15,000 inactive addresses. Open rates of 40%+ are achievable with a clean, engaged list. Most authors with deliverability problems have much larger lists and much lower open rates.
Fix #3: Review Your Content
Spam filters scan your email content for patterns associated with spam. Certain word patterns, formatting choices, and link structures increase your spam score.
• Avoid ALL CAPS subject lines or body text
• Don't use too many exclamation points in subject lines
• Keep your image-to-text ratio balanced — an email that's mostly one large image with no text looks like spam
• Use clean, short URLs rather than redirect chains or URL shorteners
• Avoid using 'Free' in subject lines as a standalone word
• Include your physical mailing address in the email footer — legally required in the US and improves deliverability
• Include a clear, easy unsubscribe link — buried unsubscribes lead to spam reports, which tank deliverability more than unsubscribes do
Fix #4: Check Whether Your Sending Domain Is Blacklisted
If your domain or sending IP has been flagged by a spam blacklist, even perfectly crafted emails will go to spam. Check your status at MXToolbox.com — type your domain name, click 'Email Health,' and it will show you if you're on any blacklists. Most blacklists have a removal request process, and legitimate senders are usually removed within a few days of requesting it.
