What sets the price

Billing unit

Vendors bill by different units: emails sent (Krabat), AI-researched contacts per month (AiSDR), active contacts (Salesforge Agent Frank), or users plus a contact allowance (Amplemarket). Compare on the unit you expect to use most.

Contract length

AiSDR's Solo plan is month-to-month and its larger plans are quarterly. Agent Frank bills quarterly or annually. Amplemarket's Startup plan is an annual term. Krabat has no subscription; spend follows emails sent and a daily budget cap.

Email infrastructure

Some tools include sending domains and mailboxes, others charge for them separately. Salesforge states email infrastructure is an extra cost for Agent Frank. Krabat sends from its own pool of pre-warmed inboxes at no extra charge.

Channels

Plans that add LinkedIn, calls or a dialer cost more than email-only plans. Krabat is email only.

Worked example

$250, the price of AiSDR's Solo month, pays for 5,000 emails on Krabat at $0.05 each. The first 600 emails on Krabat are covered by the $30 starter credits.
