Emailing tool recommendations?

Hi everyone,

I am currently looking for a better sending tool compared to what I am currently using. So, I recently just joined "Cold Emails & Lead Gen Secrets" on Skool and the coach there is LeadGen Jay.

Okay, so as I was watching one of his videos, he mentioned ReachInbox as an email sender which offers a lifetime deal, but then when I researched about it I saw mixed reviews on it.

The reason why I am kind of tempted to get it since Jay recommended it was because I tried his recommendation on leads provider which was WarpLeads that they offered unlimited export leads and it surprisingly worked for me. It was a lot cheaper compared to my previous provider. So since his last recommendation worked, I am kind of convinced to get this lifetime deal but would like to ask for more thoughts on it before paying for it.

If you might have other email senders you can recommend, please let me know too. Thanks in advance to those who can answer.
