To make sure your emails reach your community members and don’t end up in spam folders, follow these essential tips.
Writing and content
Be clear, specific, and engaging about the subject of your email
Avoid excessive capitalization and multiple exclamation marks
Avoid overly commercial phrases that trigger spam filters like "100% free" or "Click here"
Maintain a text/image ratio of about 60% text / 40% image
Use a simple font and a clear structure (titles, paragraphs, CTA)
End with a clear signature (name, company, contact) to reinforce legitimacy
- The unsubscribe link is already set up in the admin panel. It improves the email's reputation and helps prevent spam. However, it is good practice to check that it works properly beforehand
Personalization and segmentation
Tailor the content to match the recipient profile, interests, or behavior
Use filters when selecting recipients in "Select recipients" to segment your audience
Links, code and reliability
Prefer links to your own domain or to well-known websites
Do not use shortened URLs (Bitly, TinyURL...), they are often blocked
Write a good preheader text, i.e., the preview text that appears right after the subject line
Add a link to the web version of your email (optional but recommended)
Use clean, lightweight, and valid HTML code
Test your email rendering across multiple email clients (Gmail, Outlook, mobile) using tools like Litmus or Email on Acid
Errors to avoid
Don’t overuse aggressive marketing keywords
Don’t write emails that are too short (less than 50 words) or too long (over 500 words without clear structure)
Avoid using too many images or heavy GIFs
Once you've followed these tips and your email is ready, don’t hesitate to test it in the back office and also on platforms like MailTester or GlockApps to check your email’s spam score and fix any potential issues before sending.
