Leadium review
Well-reviewed and month-to-month, with strong data; but multi-channel by default, so scope it to email-only and check delivery-team fit before you commit.

Verdict
Capable, heavily-reviewed managed outbound (G2 4.3, Clutch ~4.9 across 67 reviews) with praised data quality and month-to-month contracts, which is buyer-friendly. Two caveats: it is a multi-channel shop (calling + email) by default, so an email-only buyer must scope the engagement tightly, and reviews note a bumpy first 7-10 days with 2-3 rounds of copy edits and the occasional misspelled name or broken link. No long lock-in is a real plus.

Red flags
