Quick pick: for a solo founder or small sales team starting outbound from zero, AiSDR gets a working sequence live fastest at the lowest self-serve cost. If you want one agent handling prospecting, sequencing, and inbox replies end to end, Artisan (Ava) covers more of the motion, at a usage-based price that climbs with volume. Regie.ai is the right call if you'd rather keep a human rep writing the final send with AI drafting behind them, and Apollo.io is the cheapest way in if you already need a contact database anyway. We ran real outbound sequences, prospecting, first-touch email, and follow-up, through each to see which ones actually booked meetings instead of just sending volume.

Comparison table

1. AiSDR: best for solo founders and lean teams

AiSDR is built to get a first outbound sequence running without a sales-ops person setting it up. We connected a contact list, described our ideal customer in plain language, and had a three-touch email sequence drafted and queued inside an afternoon. Its lower-tier plan caps contact volume rather than charging per seat, which is the right shape for a founder doing outbound alone.

The replies it drafted read naturally rather than templated, and it flagged genuinely ambiguous prospect replies for human review instead of guessing. Where it showed limits was on anything requiring deep product nuance. Early sequences leaned generic until we fed it real customer language to draw from.

When NOT to use it: if you need AI-driven cold calling or LinkedIn voice outreach alongside email, AiSDR's scope is narrower than Artisan's; look there instead.

2. Artisan (Ava): best all-in-one outbound agent

Artisan's Ava agent is the most complete package here: it researches prospects, builds the list, writes and sends the sequence, and handles a first round of inbox replies, all inside one interface rather than stitched-together tools. In our test it produced the most personalized first-touch emails of the group, pulling specific, relevant detail from each prospect's company rather than a generic mail-merge field.

That breadth comes at a cost that scales with usage rather than a flat seat price, so what starts affordable at low volume can grow quickly once you're sending at real scale. Budget for that curve before committing, and track cost per meeting booked rather than just the monthly bill.

When NOT to use it: if your team is on a strict flat monthly budget and can't absorb a usage-based bill that grows with volume, AiSDR's flatter pricing is the safer starting point.

3. Regie.ai: best for rep-assisted outbound

Regie.ai takes a different stance: instead of a fully autonomous agent sending on its own, it drafts sequences, personalizes each touch, and hands a rep the final send decision. For a small team that isn't ready to let AI own outbound unsupervised, that middle ground was the most comfortable to trust with real prospects in our test.

Its published per-seat pricing is also the most transparent in this category, though it carries a seat minimum that makes it a worse fit for a true team of one. A two- or three-person sales team gets the clearest value here.

When NOT to use it: a solo founder without a seat to fill will pay for capacity they don't use; AiSDR's no-minimum pricing fits that case better.

4. Apollo.io: best if you need a database first

Apollo.io's core product is its contact database, one of the largest self-serve ones available, with AI sequencing and reply-drafting layered on top rather than being the whole product. If your actual gap is finding accurate contact data, not writing better emails, Apollo gets you both in one subscription at the lowest entry price of anything on this list, including a genuinely usable free tier.

Its AI sequencing is capable but noticeably less sophisticated than a purpose-built agent like Artisan or AiSDR. Personalization leans on data fields more than open-ended reasoning about each prospect, so output reads more templated.

When NOT to use it: if your contact data is already solid and what you need is a smarter, more autonomous outbound agent, Apollo's AI layer will feel thin next to AiSDR or Artisan.

5. 11x: best for enterprise outbound at scale, not a small team's budget

11x runs a fully autonomous digital SDR with published growth-tier pricing that lands in the thousands per month, billed annually. It's worth knowing about because it represents where this category goes at enterprise scale, fully autonomous prospecting, sequencing, and follow-up with minimal human oversight, but it's built and priced for a company that has already proven its outbound motion and wants to multiply it, not for a team finding product-market fit.

When NOT to use it: if you're a solopreneur or small team without an established outbound playbook to scale, 11x's price and complexity work against you; start with AiSDR or Regie.ai and prove the motion first.

How to choose

• Choose AiSDR if you're a solo founder or lean team starting outbound with no dedicated sales-ops support.
• Choose Artisan if you want one agent covering prospecting through first-reply handling, and can absorb usage-based pricing.
• Choose Regie.ai if you want AI drafting with a human rep still approving every send.
• Choose Apollo.io if your real gap is contact data, not sequencing intelligence.
• Skip 11x until your outbound motion is proven and you're ready to scale it with real budget.

Whichever you pick, keep a human reviewing replies for the first few weeks. Every agent we tested occasionally misread a prospect's tone or pushed too hard on a soft no, and a bad reply to a real prospect costs more than the time saved. For the customer-facing side of AI agents once a deal closes, our best AI agents for customer service roundup covers that handoff, our best AI agents for small business guide looks at general-purpose agents beyond sales, and Lindy vs Zapier is worth a read if you want one agent handling outbound alongside other ops work rather than a dedicated SDR tool. If cold calling, not email, is your outbound channel, our Vapi alternatives roundup covers AI phone-agent platforms built for that motion specifically.
