The best Messaging Apps newsletters

Promotional but informative posts from the Z-TEXT blockchain messenger, explaining privacy concepts such as metadata, IP exposure, Tor and post-quantum key exchange through the lens of its own product. Each issue pairs a themed 'postcard' or awareness-day hook with sourced facts and product details.

This is promotional content from Octopods, a vendor selling an integration between LINE or WhatsApp and HubSpot. The posts explain how messaging conversations can be linked to HubSpot contacts and deals, with the product presented as the solution throughout.
