Who should choose which
Choose AiSDR if
- you want to pay per person with no monthly fee. Pay as you go charges $1.50 for each person prospected, daily, with no contract.
- you want someone to run it for you. AiSDR lists a managed service at $149 per campaign and a fully managed one at $2,500 a month.
- your CRM is Salesforce, which AiSDR lists on Team plans and Sellinger shows as coming soon.
- you write to prospects in many languages, since AiSDR says it supports outreach in any written language.
Choose Sellinger if
- you want to reach people on WhatsApp, Instagram or live chat, which the AiSDR pages we checked do not list.
- you want a flat monthly price per channel, such as a LinkedIn agent at $198 a month, instead of a charge for every person.
- you want deals, contacts and the whole conversation history in a CRM inside the tool, which AiSDR says it is not.
- you want a hosted MCP connector for Claude and ChatGPT, or a REST API from the Full Stack bundle up, neither of which AiSDR lists.
What it costs per person against per month
AiSDR pay as you go includes research, list building and writing in the $1.50 per person, plus 1 user, 1 domain, 3 mailboxes and 1 LinkedIn account. A Sellinger LinkedIn agent is $198 a month for one or two agents and does not rise with each person, but it has daily and weekly invitation limits, 20 and 150 by default, so a very long list needs more agents. At 150 invitations a week one agent can invite about 600 people over four weeks, so the 500 row sits near its ceiling.
The crossover is about 132 people a month, which is $198 divided by $1.50. Below that, pay as you go costs less; above it, one agent costs less. A Sellinger LinkedIn agent covers LinkedIn only, so email adds a plan from $39 a month.
AiSDR's pricing page gives two starting prices for a campaign, $7.50 and $3, and its Ami product page still mentions a Solo plan at $250 that the pricing page no longer shows. We used the pricing page, dated 15 October 2026.
| People prospected | AiSDR pay as you go | Sellinger LinkedIn agent |
|---|---|---|
| 100 in a month | $150 (100 people at $1.50) | $198 (1 agent) |
| 200 in a month | $300 (200 people at $1.50) | $198 (1 agent) |
| 500 in a month | $750 (500 people at $1.50) | $198 (1 agent) |
Who writes, replies and books
AiSDR's agent replies on email and LinkedIn within minutes, handles objections, qualifies and books, and can run with a person approving. Its managed service add ons are run by AiSDR itself, and Team plans come with a dedicated GTM engineer.
Sellinger's agent drafts the opener and every follow up, replies, and books the meeting across its channels. A campaign can hold each message for approval, and a person can take over a conversation at any point.
Contracts, limits and what pay as you go includes
Pay as you go has no plan limit and no contract. Team plans have a monthly contact limit and run on quarterly or annual contracts, and an annual plan is 20% cheaper than a quarterly one.
- The pricing page says cancel anytime. The terms, last updated in 2024, say early cancellation gives no refund of prepaid fees and fees through the term remain due.
- Extra mailboxes are $33 per setup. Salesforce, LinkedIn signals, website visitor tracking, AI video and AI voice notes are on Team plans only.
- AiSDR says setup takes less than 1 business day, or about 3 days for many domains.
Switching between AiSDR and Sellinger
Pay as you go has no contract, so you can run Sellinger beside AiSDR with no cancellation date to plan around.
- Connect a LinkedIn account and a mailbox in Sellinger that AiSDR does not use.
- Add people AiSDR is not already contacting, from a CSV or the contact database.
- Write your offer in a few lines and approve the first batch of messages.
- After a few weeks, compare cost per reply and per meeting on both sides.
- Ami's research, campaigns and reply history do not move across. We have not checked what AiSDR exports.
- On a Team plan, check the term and the cancellation wording in AiSDR's terms before you move.
