I read that we can only use one email account, is that correct? However, it's strongly recommended not to send more than 25 prospecting emails per day per account. That amounts to 500 prospecting emails per month for a single account, which is very low. That's why we use cold emailing systems with dozens of email accounts to prospect effectively.

So I thought OK, their email sending system is negligible, it's the number of monthly contacts that matters. For example, we export 35K contacts per month with 10 codes, verify the emails with a specific tool, and feed our cold emailing campaigns by sending our emails with specific tools that allow us to use multiple email accounts. But apparently, we can't export more than 300 contacts per month!

Therefore, I don't understand how to utilize the 35K monthly contacts? Can you explain this to me?
