Is Warmbox worth the price?
Warmbox's pricing is fair for smaller users but can become expensive quickly for growing teams.
The 'Solo' tier at $15/month (yearly) or $19/month (monthly) is reasonable for a single inbox. However, the jump to 'Start-up' at $69/month (yearly) or $79/month (monthly) for only 3 inboxes is a significant increase.
