Newsletter Operator

What it is.

Matt McGarry started Newsletter Operator on January 16, 2023. He also runs GrowLetter, whose site says its team has generated over 10,000,000 email subscribers for clients. The newsletter site puts its own list above 50,000 readers.

Issues cover list growth, channel mechanics, and money. Recent ones went through SMS list building and income streams for publishers. Numbers sit in the body, including the open-rate case for texting.

The archive is open on the site and sorted into growth and strategy topics. Platform commentary turns up too, including beehiiv against Kit.

Questions about Lifecycle & Email

Does paid acquisition make sense for an email list?
Where does SMS fit next to email?
Strengths
  • Written by the founder of a newsletter growth agency, so the tactics come from paid work.
  • Pieces quote numbers from his own sends, including open-rate and milestone figures.
  • Covers SMS next to email, which lifecycle teams usually own together.
  • Free, with the archive open and no signup wall on individual issues.
Limitations
  • Creator and media economy first. Less on B2B lifecycle, CRM, or product-led email.
  • Written for people whose newsletter is the product, so in-product email gets little room.
  • The site does not state how often it lands, so treat the schedule as unconfirmed.
Skip this if
  • Skip it if you already read Inbox Collective and want one newsletter send.
