Getting a message out and knowing whether it landed. Most of this category is email, because email is still the channel a company owns rather than rents. The tools differ by who is holding them: Resend is an API for developers sending transactional mail from their own application, Loops is built for software companies that want lifecycle email without an enterprise campaign builder, Mailchimp is the general-purpose option for lists that outgrew a spreadsheet, and beehiiv is for people whose product is the newsletter itself. Buffer handles the social side by queueing posts against a schedule. HubSpot is the other shape entirely: marketing, sales and support sharing one contact record, which is powerful when a company is big enough to need it and heavy when it is not.
