Common questions
Why does it matter that CMass sends from Gmail vs. Mailchimp's servers?
Emails from Gmail land in the inbox with your name and address — recipients see 'sarah@company.com', not a Mailchimp sending domain. For B2B outreach, this dramatically improves reply rates and trust. For branded newsletters, Mailchimp's infrastructure is more appropriate.
Can CMass handle newsletter-style HTML emails?
CMass supports HTML email templates with merge tags. It doesn't have a drag-and-drop builder. For polished, design-heavy newsletters, Mailchimp is the better tool. For text-or-lightly-formatted outreach emails, CMass's editor is sufficient.
How does CMass pricing compare to Mailchimp for large lists?
Mailchimp charges by the number of contacts in your audience — 10,000 contacts costs $100+/mo on Essentials. CMass charges a flat $29/mo regardless of list size (subject to daily send limits). For teams with large lists but moderate daily volume, CMass can be significantly cheaper.
Does CMass handle unsubscribes and GDPR compliance?
Yes. Every CMass campaign includes a one-click unsubscribe link. Contacts who unsubscribe are automatically suppressed from future campaigns. CMass also provides data deletion and data export endpoints for GDPR compliance.
