How the work actually splits

Choose Smartlead if — honest fit

you are an agency running very high email volume and want granular infrastructure control.

Choose Instaboost if — honest fit

you want outbound to run as one continuing loop — sourcing through booked meetings — without hiring someone to work the handoffs.

Both are capable products. The difference is what happens after the first send: Smartlead gives you a place to run campaigns; Instaboost owns the continuing loop.

Instaboost runs the continuing outbound loop — sourcing, campaigns, follow-ups, replies, and refills — after one setup.
