An outbound stack is three purchases that get talked about as one. Data (who to contact and how to reach them), engagement (the sending infrastructure that gets the message delivered), and increasingly an AI layer that drafts and sequences on its own. Buying all three from one vendor is convenient and usually more expensive than buying the two that matter to you.
Every vendor in this category prices a seat and then meters what that seat can actually do. Apollo.io is $59 per user monthly (about $49 annually) with roughly 1,000 credits that expire each cycle. Lusha runs about $37 per user annually with seat minimums. RocketReach works out around $33 a month on annual billing for 1,200 lookups a year. Clay is a different animal ($185 a month at Launch) because you are paying for an enrichment workbench that chains dozens of data providers, not a single database. Seamless.AI lists $147 a month for 250 credits a month. Before comparing prices, compare what one credit buys: a verified mobile number costs several credits at most vendors, and that is usually the number you actually need. Side-by-side ratings for all of them sit in the sales intelligence hub.
Sending tools are the cheap part: Smartlead starts at $39 a month for 2,000 leads and 6,000 emails, lemlist Email Pro is $39 per user, Instantly Growth is $47 for 5,000 sends. The cost that does not appear on the pricing page is deliverability infrastructure (domains, mailboxes, and warmup) which is what actually decides whether the sequence lands. Vendors that bundle unlimited mailboxes and warmup (Smartlead and Instantly both do) are cheaper in practice than a lower sticker price that charges per sending account.
The autonomous tier is where budgets break. Reply.io opens its AI SDR plan around $139 per user per month, and AiSDR starts near $900 a month billed quarterly. That is a floor of roughly $10,000 a year for software that still needs a human editing its judgement about who is worth contacting. It earns out when your list is large and your motion is repeatable; it does not when your ICP is narrow enough that a good rep with a good data tool covers it by hand.
Head-to-heads and how-tos for the tools above.
Clay is a credit-based GTM data workbench that chains 100+ providers; Apollo.io is a default contact database with built-in sequencing and dialing. Here's how to choose in 2026.
"AI SDR" promises an autonomous sales rep that prospects, writes, and books meetings while you sleep. Here's what that actually delivers in 2026, where it quietly fails, and how Reply.io, AiSDR, and Apollo compare.
Apollo, Seamless.AI, Lusha, RocketReach and Clay all promise accurate B2B contact data, but they make very different trade-offs on coverage, data compliance and what you'll really pay. Here's an honest breakdown to help you pick.
