Frequently asked questions You write a good newsletter, you send it, and then you find out that half your readers never saw it because it landed in spam or promotions. Authors, coaches and small businesses run into this more than ever since Gmail and Yahoo tightened their rules for senders. If you have a **newsletter going to spam** , this guide explains why and what to fix. **Quick answer:** Most newsletters go to spam because the sending domain is not authenticated (SPF, DKIM and DMARC), the list includes people who never engage, or the emails look like bulk marketing without an easy unsubscribe. Authenticate your domain with your email platform, send from your own domain, clean inactive subscribers, and include one-click unsubscribe. ## Why newsletters end up in spam Email providers decide where a message lands based on who sent it, whether they can verify it, and how recipients behave. Google’s sender guidelines set out what bulk senders must do, including authentication and easy unsubscribe, and they apply most strictly to people sending large volumes to Gmail addresses ([Gmail sender guidelines](https://support.google.com/a/answer/81126?hl=en)). The most common causes for small senders: 1. Sending from a free address like @gmail.com through an email platform. 2. No SPF, DKIM or DMARC records for your domain. 3. Old or bought lists with lots of people who never open. 4. No visible or one-click unsubscribe. 5. Sudden large sends after months of silence. ## Step 1: Send from your own domain Use an address like hello@yourname.com rather than a free Gmail or Yahoo address. Free providers publish policies that tell other mail servers to distrust their addresses when sent through third-party platforms, so your newsletter looks suspicious by default. ## Step 2: Authenticate your domain | Record | What it does | Where you set it | | --- | --- | --- | | SPF | Lists which services are allowed to send mail for your domain | DNS, using the value from your email platform | | DKIM | Adds a digital signature proving the email was not altered | DNS, using keys from your email platform | | DMARC | Tells providers what to do if SPF or DKIM fail, and sends you reports | DNS, starting with a monitoring policy | Every major platform, including MailerLite, Kit, Mailchimp, Flodesk and GoHighLevel, has a domain authentication screen that gives you the exact records to add at your domain registrar or DNS host. Be careful not to create two SPF records; merge them into one. ## Step 3: Make unsubscribing easy Include a clear unsubscribe link in every email. For bulk senders, Google requires one-click unsubscribe, which most platforms add automatically when enabled. It feels counterintuitive, but people who cannot find the unsubscribe link click “Report spam” instead, which hurts you far more. ## Step 4: Clean your list - Remove hard bounces straight away (most platforms do this automatically). - Send a re-engagement email to people who have not opened in six months, then remove those who still do not respond. - Never buy or rent lists. - Use double opt-in if you get lots of fake or mistyped sign-ups. Open rates are not perfectly reliable because of privacy features in some email apps, so also look at clicks and replies. ## Step 5: Keep a steady rhythm Sending regularly, even monthly, keeps providers and readers familiar with you. If you have been silent for a long time, start with a smaller send to your most engaged subscribers before emailing everyone. ## Step 6: Write like a person - Plain, honest subject lines. Avoid all-caps and excessive punctuation. - A sensible balance of text and images, not one big image. - Ask readers to reply sometimes. Replies are a strong positive signal. - Ask new subscribers to move your email to their main inbox. ## Quick diagnostic checklist - Sending from your own domain, not a free address - SPF, DKIM and DMARC set and passing - One-click unsubscribe enabled - Inactive subscribers cleaned in the last six months - Spam complaint rate low in your platform’s reports - Consistent sending schedule If you are building your list from a lead magnet, see [lead magnet ideas that turn visitors into subscribers](https://sukeshdas.com/lead-magnet-ideas-for-coaches/).

Usually because your domain is not authenticated, you send from a free email address, your list includes many inactive subscribers, or unsubscribing is hard. ### Do small senders need DMARC? It is strongly recommended for everyone and required for bulk senders to Gmail. Start with a monitoring policy and tighten it once everything passes. ### Why do my emails go to the Promotions tab? Gmail places marketing emails in Promotions by design. It is not spam. Asking readers to move you to Primary and writing in a personal style can help. ### Should I use double opt-in? If you see fake sign-ups or many bounces, yes. It slightly reduces sign-ups but improves list quality and deliverability. ### How often should I clean my email list? Review inactive subscribers every three to six months and run a re-engagement campaign before removing them.
