Frequently Asked Questions
What is mass email marketing?
Mass email marketing is sending a single email campaign to a large group of subscribers simultaneously. It's used for newsletters, promotions, announcements, and event invitations. Requires a dedicated platform (not Gmail/Outlook) for deliverability and compliance.
How many emails can I send for free?
Brevo's free plan allows 300 emails per day (~9,000/month) to unlimited contacts. MailerLite offers 12,000/month to 1,000 contacts. These are the most generous free plans for mass email sending.
Will mass emails go to spam?
Not if done correctly. Use a dedicated email platform, authenticate your domain (SPF/DKIM/DMARC), send only to opted-in contacts, maintain list hygiene, and avoid spam trigger words. See our deliverability guide for details.
