Is there a truly free email marketing platform?
Yes. Mailchimp offers unlimited free use up to 500 contacts and 1,000 emails per day. Brevo provides free email sending (up to 300 per day). Substack is free for newsletter creators. However, free tiers typically have limited features compared to paid plans.
