The Premium plan at $19.99/month (or $16/month annually) offers 250 AI messages, which may be sufficient for moderate users. The Ultra plan at $44.99/month (or $29/month annually) provides unlimited AI messages, catering to heavy users. Mailbutler also offers a freemium model with a free Starter plan that includes limited features and a Mailbutler watermark. The Professional plan at $7/user/month is a cost-effective option for individuals, while the Smart plan at $11/user/month offers more advanced features.
