Create effective email content
Formatting issues, unusual links, or attachments can trigger spam filters. Pay attention to the following best practices when writing emails.
Message format
Use a standards compliant email client that supports both HTML and plain text versions.
Keep layouts simple and avoid overly complex designs with many images.
Avoid invisible tracking tools or active components. Link to rich content on your website instead.
Links
Only include links to reputable websites.
Do not use IP addresses or shortened URLs. Always use a clear domain name.
Word choice
Use personalised greetings and natural language.
Avoid excessive punctuation, capital letters, and common spam terms.
Do not include statements claiming the email is not spam.
Avoid references to typical spam related topics such as medications, financial schemes, or explicit content.
Attachments
Use clear and simple file names if attachments are necessary.
Prefer cloud services such as Microsoft OneDrive or Google Drive to share files via links.
Avoid attachments whenever possible as they can increase spam detection.
