Can I send marketing emails (newsletters) with Missive?
Most likely not. Missive sends emails via your SMTP server and it’s not recommended to send a massive volume of emails via an SMTP server because your delivery rate may be negatively affected. Your regular business emails might start getting automatically marked as spam by Gmail, Office 365, etc. This can be a nightmarish situation for a business.
You should use a platform built for sending marketing emails like Mailchimp, Campaign Monitor, Postmark and many others.
