I have a big issue here: this is essentially bootstrapping spreadsheets to do only a singular task for what seems to be free, until it's not.
The competitor to this service would be Monday, which offers a plethora of automation techniques and a straightforward(ish) API to create your own.
There is a huge security concern in giving Gmail write and also Google Drive permissions as well.
Lastly, I would consider this to be something that Gemini can/will accomplish in due time
So what makes this competitive?
Congratulations on launching. Brings back memories of WordPerfect 4's mail merge around 1991 and building an API using MS Office's mail merge in 2008. Good times.
Surprised that Google Office doesn't do mail merge, so I googled it and got this: https://developers.google.com/apps-script/samples/automation...
Good luck.
What do the privacy aspect of this? I would love to use it but can't see my company wanting the contents to be sent through an additional third party?
Really nice, specially for small business & indie hackers. Best of the lucks!
the spreadsheet is not going anywhere
