You shouldn’t have to overpay for cold email tools. With Mystrika, you won’t.

It does cold email warmup, sequences, unified inbox, and AI writing - all in one place. Every other tool that does this charges somewhere between $100 and $500 a month. Mystrika has a free plan. 500 prospects. No expiry. No card.

The people who consistently book meetings from cold email aren’t smarter. They just stopped leaving money on the table.
