Error after installing bulk-mail-cli on Linux Mint 20.3 Cinnamon

[loketi]

Hello amazing people! So I've just installed bulk-mail-cli using "npm i -g bulk-mail-cli" and the process completed successfully but then I saw this message at the bottom of the terminal window. Has anyone seen the same? should i worry about it? and how do I fix this? thanks a ton!

The Error Message:

(Use node --trace-deprecation ... to show where the warning was created)

When I use "node --trace-deprecation ...` to trace the warning. I get....

shangwe@shangwe-Inspiron-3542:~$ node --trace-deprecation

Hi @loketi!
I think you should downgrade Node to v14, that should make the error go away. Let me know if that works.

Thank you again. I downgraded node to v14.17.3 (LTS) and it's working fine. No error. Btw. is it possible to use SendGrid Web API instead of SMTP relay to send the emails?
