Any agencies that offer newsletter nurturing as a service?

1. Reach out to clients who have decent website traffic, but no newsletter. 2. Sell to implement an exit intent newsletter popup / lead msgnet and other things for the client to catch traffic that isn't ready to convert yet. 3. Run a newsletter on a relevant topic for the audience or could repurpose their blog/podcast content into a newsletter, with list management, welcome automations, surveys and pitching of products or services of the client.
