Direct Mail API (Postalytics, PostGrid, Lob)

I’d like to implement a direct mail service into my app so that users can take a list of addresses and send out mailers, flyers, postcards, etc. Also users could customize a template using Bubble data (image, logo, copy, contact info, etc.).

I’m aware of APIs like Postalytics, PostGrid, and Lob, but it looks like Lob is the only one to have a Bubble plugin. Does anyone have experience configuring any of them in the API Connector?

UPDATE: I’m going to take a deeper dive into the Lob plugin by @copilot to see if it has what I need.

One of the use-case I have been working on is using

HTML code can be used as input of the action, so a WYSIWYG visual editor could be used to customise template or defined them on AWS side.

It also supports template variables.

Thanks for this, @redvivi. I’m actually looking to send physical mail, but I could use this for another application.

Oops apologies @sydney22 !
If you have a pre-selected provider to send mail via API, feel free for DM use for a plugin.
