Frequently Asked Questions
Can I switch plans anytime?
Yes! You can upgrade or downgrade your plan directly from the Billing dashboard. Upgrades take effect immediately with proration.
How does Easy DKIM domain verification work?
Mailzo automatically creates three 2048-bit DKIM tokens and SPF records. Once added to your DNS provider (e.g., GoDaddy, Cloudflare), our backend verifies propagation with 1 click.
Are suppression and unsubscribes automatic?
Yes. Contacts who unsubscribe via the built-in 1-click unsubscribe link or who encounter hard bounces are marked as unsubscribed and protected against further delivery.
