Salut Patrick !
You’ll need to send your emails from another tool (Apollo, Lemlist, Outreach, etc). To make sure you’re not getting flagged as spam, it’s good to use another domain (one you can lose if things go badly), warm up that domain (send emails from it to train Gmail, etc), set up DKIM, DMARC, etc, etc.
How big is your list? LinkedIn could be easier for this.
