AI SDR software, AI SDR agents and AI BDR tools, compared by what they actually cost

The phrase AI SDR got attached to three product categories inside about eighteen months, and they are not substitutes for each other. The first is the autonomous outbound agent: 11x's Alice, Artisan's Ava, AiSDR. You give it an ICP, it builds the list, researches each contact, writes a distinct email, sends it and handles the first reply. The second is the AI-assisted sales engagement platform, where Regie.ai sits alongside cold email software including this one. The AI does research and drafting, a human keeps the strategy and the send decision. The third is the inbound agent, which is what Qualified's Piper is. It works the visitors already on your website, qualifies them and pushes them into a booking flow. It does not do outbound. A buyer who searches for AI SDR software, books a Qualified demo and signs is going to be surprised, because they bought a product that will never send a cold email.

The more expensive confusion is the pricing unit, and it is the reason so many outbound ROI comparisons come out wrong by an order of magnitude. Autonomous AI SDRs charge per contact researched. AiSDR's published plans are $250 a month for 200 contacts, $900 for 800 and $2,500 for 2,500, which lands between $1.00 and $1.25 for every contact the system touches. Sending software charges per mailbox or per seat and treats your contact count as your business. So when a team lines up $900 a month against a $97 a month sending tool and concludes the AI SDR is nine times the price, they have compared two different units. The honest comparison is what the $900 buys that the $97 does not, which is the list, the research and the copy. Whether that is worth roughly a dollar a contact depends entirely on your deal size, and for a $40,000 ACV it very often is.

Seat minimums are the second number that does not appear in roundups. Regie.ai publishes $180 per user per month for its AI SEP tier, which reads like the cheapest serious option on this page until you get to the 10 seat minimum on an annual contract. The actual floor is $1,800 a month, and that tier includes no data credits. The Force Multiplier Rep tier is $499 per user with a 5 seat minimum, so $2,495 a month, and it does include roughly 120,000 credits, about 1,000 accounts or 4,000 contacts. Mailbox rotation is a separate $50 to $100 per user per month add-on and the parallel dialer is $1,800 per user per year. None of that is hidden, it is published on their own page, but a per-seat headline with a double-digit seat minimum is not a per-seat price in any way a five person team would recognize.

Then there is the question of what an AI SDR fixes, which is narrower than the category implies. Every one of these products compresses the same step: turning a name into a researched, written, sent email. That step really was the bottleneck for a lot of teams, and automating it is genuinely valuable. What none of them do is decide who to email or what to say that a stranger would care about. If your reply rate is low because the ICP is wrong or the offer is weak, an AI SDR does not repair that, it reproduces it faster and at higher volume, which on a cold domain is an active liability rather than a neutral one. The 24/7 claim is also softer than it sounds when the channel is email, because the binding constraint is mailbox capacity at 20 to 50 sends a day per warmed inbox, not how many hours a human is awake. Adding hours to a system limited by mailboxes changes nothing.

AutoMail is in the second category and it is worth being plain about that. It writes hyper-personalized sequences from researched detail, connects Google Workspace and Microsoft 365 mailboxes over OAuth, warms every mailbox, rotates volume across the pool, checks SPF, DKIM and DMARC alignment on each sending domain before it sends, follows up on its own, detects replies in the mailbox and pauses the sequence the moment a person answers, then classifies intent and routes meeting-ready replies to your booking link. It does not sell you the contact database and it does not pretend to replace the judgment of the person running the campaign. You bring the list and the positioning, the software does the research, the writing, the deliverability work and the follow-up. If what you want is a vendor that owns the whole motion end to end and you are comfortable paying about a dollar per contact for it, an autonomous AI SDR is the honest recommendation and the table below tells you what each one charges.

It works hand in hand with cold email tool, email outreach software and ai email outreach, all included in one flat cold email software price.
