FREQUENTLY ASKED QUESTIONS
Clear Answers for Your Team
Everything you need to know about deliverability, pricing, and compliance.
How does Centimailer pricing differ from Substack, Mailchimp, or Beehiiv?
Most newsletter platforms charge monthly fees based on how many subscribers exist in your database, whether you email them or not. Centimailer only charges for sent volume. If you have 50,000 subscribers but send bi-weekly, you pay significantly less with Centimailer.
Are Google and Yahoo bulk sender requirements supported?
Yes. Centimailer automatically inserts RFC 8058 one-click List-Unsubscribe headers, aligns SPF and DKIM signatures, and supports strict DMARC policies to satisfy all modern inbox provider rules.
Can I import existing newsletter subscriber lists?
Yes. You can import standard CSV files with subscriber email addresses, names, and custom attributes. Centimailer automatically de-duplicates entries and removes formatting errors.
Does Centimailer place its own logo or branding in my newsletters?
No. Centimailer provides 100% white-label ready sending. There are no "Powered by Centimailer" badges or watermarks in your outgoing emails.
