Frequently Asked Questions
Are free email marketing tools really free?
Yes, all platforms listed here offer genuinely free plans with no credit card required. The trade-offs are contact/email limits, platform branding on your emails, and restricted access to advanced features like A/B testing and complex automation.
Which free email tool has the best deliverability?
Mailchimp and Brevo consistently score highest in third-party deliverability tests. However, deliverability depends more on your sending practices (list quality, engagement rates, authentication setup) than on the platform itself. All platforms on this list maintain acceptable deliverability for their free tiers.
Can I remove the platform branding on free plans?
Generally no. Almost all free plans include the platform's branding (logo or "Sent via...") in your emails. HubSpot includes its branding but in a less intrusive way. To remove branding, you typically need to upgrade to the lowest paid plan.
When should I upgrade from a free plan?
Upgrade when you hit any of these triggers: your contact list exceeds the free limit, you need automation for revenue-generating flows (abandoned cart, welcome series), you want A/B testing to optimize campaigns, or the platform branding looks unprofessional for your brand.
Can I switch between free email platforms easily?
Yes. Most platforms allow CSV export of your contact list. Import into the new platform, set up your templates and automations, and you are ready. The process typically takes 1-3 hours. Note that subscriber engagement data (open rates, click history) may not transfer between platforms.
