Frequently Asked Questions about Sendmatico

How does SendMatico's credit system work compared to monthly cold email plans?

SendMatico charges per credit consumed in campaigns rather than a fixed monthly subscription, and unused credits stay in your account indefinitely. You buy credits upfront at tiered rates, from $49 for 10,000 credits on the Starter plan down to $0.0020 per credit on Scale, with no expiration or monthly commitment.

Can I manage multiple client accounts in one SendMatico dashboard?

Yes, SendMatico's multi-inbox infrastructure is designed specifically for agencies to manage separate client campaigns within a unified dashboard. You can set up multiple inboxes per client, control team and client access separately, and track each account's performance independently.

Does SendMatico automatically detect replies and handle follow-ups?

SendMatico includes automatic reply detection that identifies responses to your cold emails, saving you from manual inbox review. You can then set up multi-step campaign automation to trigger follow-ups based on replies, which the tool can execute across your client accounts.

How does SendMatico track meeting outcomes and prove ROI to clients?

SendMatico has integrated meeting tracking and ROI reporting built into the dashboard, letting you log meetings generated from campaigns and tie them back to specific outreach efforts. This means you can show clients exactly which cold email sequences produced meetings and measure the return on each campaign.
