No credit card required. Free to use.
Why MailGuide?
Personal Touch
Emails come from your own email address — not a bulk mail platform. Recipients see a real person, not a marketing blast.
Write Once, Send Many
Use placeholders like {Name} and {Company} to automatically personalize each email. No more copy-paste.
Filter & Target
Upload your CSV or Excel file, filter by any field, and select exactly who should receive your message.
