How Sending Just a Few Group Emails Can Get You Blacklisted (And How to Avoid It)
A mass email list refers to sending the same or similar email to multiple recipients at once, especially when they didn’t explicitly request or subscribe to receive those emails. Many people think this only applies to large companies or mailing lists with hundreds of addresses, but in reality, even sending the same email to 5–10 recipients (especially if they’re not BCC’d) can trigger spam filters. Email providers like Microsoft (Outlook/Hotmail), Gmail, and others monitor patterns like this to detect potential spam or phishing behavior. If you’re repeatedly sending group messages from a personal or business domain email, it can damage your domain reputation and get you listed on spam blacklists. That’s why tools like Mailchimp or MailerLite — which are designed for group emailing — are important: they handle delivery properly, include required unsubscribe options, and follow strict sending protocols that keep your emails compliant and out of spam folders.
