10k emails per month is generous. Maybe too generous. Selfishly I wish they didn't increase the price, but as a aspiring SaaS founder, it's totally fair that they did. They do provide value. But 625 emails per month amounts to around 20 emails per day. If you have 5 customers, then you can send them 4 emails per day. So not much. I wish they found a middle ground here.
Even if I sent 5000 messages one month, I'd pay around $4.
This is not even close to a significant cost.
