Don't just take our word for it — see what real customers are saying!
The self-healing mechanism that they advertised just didn't work at all for me.
Only used MailScale for 1 month, first week was OK, by week 2 deliverability was <50%.”
Support was slow and resolution claims did not match reality.
Amazing service. You are in trusted hands with Cleverly. They know they’re business well.
She was always checking in, quick to make adjustments, and focused on getting results.
What stands out most is their ability to generate high-quality meetings.
Mailscale combines AI outreach automation with dedicated account support. Cleverly provides an agency-managed service covering prospect research, messaging, campaign optimization, and lead handling. The choice depends on whether you prefer an AI platform or an agency team managing your outreach.
No. Its current Agentic Mailscale offering extends beyond inbox infrastructure to include lead sourcing, AI copywriting, and reply handling. Older inbox-only comparisons no longer describe its full offering.
Yes. Mailscale offers an AI Reply Agent that can handle responses and book meetings. Buyers should confirm whether that module is included in their proposed plan.
Its current offering uses custom, modular pricing. Your quote depends on the services selected, so compare the complete proposed package with Cleverly’s managed service when assessing cost.
Cleverly fits companies that want a team to take responsibility for cold email strategy and execution. Its managed service connects targeting, copywriting, testing, and follow-up around generating qualified conversations, making it suitable for businesses without an internal outbound team.
