AI SDR costs compared: FirstSales, Explee, Gojiberry, Raechly

Four tools now sell some version of an AI sales rep. The promise is the same everywhere: describe who you want, and software finds them, writes to them and hands you the people who answer. Under that promise they differ in ways that decide whether it works for you, and the biggest one isn’t the price. It’s whose inbox the mail goes out from.

We build one of them, Raechly, so read this with that in mind. Every competitor figure links to its source, and where a rival is better we say so.

The short answer

• Explee if you want meetings without setting anything up and don’t mind the mail going out from inboxes you don’t own. It’s the cheapest when the tool has to find the people.
• FirstSales if you want an email-first AI SDR on your own mailboxes, with lead finding and calendar booking inside the product.
• Gojiberry if your buyers are active on LinkedIn and you want them messaged soon after they show interest.
• Raechly if you want senders set up for you on a domain nobody else sends from, want to approve every email before it goes, and want to run outbound from Claude or Cursor with a pipeline after the first reply.

Four ways to charge for the same job

	How you pay	Sends from	Finds leads
Raechly	Monthly credits, $29 to $499	Senders on a domain bought for you; your own inboxes on Business	Yes, 15 credits each
FirstSales	Monthly credits, $29 to $499	Your Gmail, Outlook or SMTP	Yes, 15 credits each
Explee	Per email, about $0.04	Explee’s pre-warmed inboxes	Included
Gojiberry	$99 a month flat	Your LinkedIn account	Included, from signals

Raechly and FirstSales have the same plans. Same four tiers, same credit allowances (4,000 credits for $29 up to 175,000 for $499), and both charge 15 credits to find a person. Raechly charges 1 to send and 2 for an AI-written email; FirstSales sells a premium AI email at 8 and a deep enrich at 35. Put FirstSales’ pricing next to ours and there is little to choose between them, so the difference has to come from what each does with the credits.

Explee has no plan at all. Its pricing page puts $30 at about 750 emails, with finding and writing folded in. Gojiberry lists one plan on its homepage: Pro at $99 a month for two AI agents and up to 1,800 people contacted. Its pricing page returns a 404.

What 1,000 prospects cost on each

The cheapest tool changes with the job, so here are three.

You have 1,000 contacts and want one AI-written email each

• Raechly: 3 credits each (2 to write, 1 to send), 3,000 in all. That fits inside the $29 Starter plan with 1,000 credits to spare.
• FirstSales: the same 3,000 credits on the same $29 plan.
• Explee: about $40 at its published rate.
• Gojiberry: doesn’t work this way. It finds its own people from signals.

With a list in hand, the credit plans win.

You need 1,000 new people found and emailed once

• Explee: still about $40, because the database is included.
• Gojiberry: $99 for the month, which covers up to 1,800 people, mostly reached on LinkedIn.
• FirstSales: 18 credits each (15 to find, 2 to write, 1 to send), 18,000 in all. That needs the $149 Pro plan, or Growth plus top-ups.
• Raechly: the same 18 credits each as FirstSales, 18,000 in all. You confirm who the campaign should reach first, after a count and five anonymous examples.

When the tool has to find the people, Explee is cheapest by a distance.

You keep 10 mailboxes warm for a month

• FirstSales: included on every plan.
• Raechly: included. Warmup costs nothing on any plan, and ten senders fit inside Pro’s twelve.
• Explee and Gojiberry: nothing to warm. Explee’s inboxes arrive warm, and LinkedIn has no warmup.

Until October 2026 Raechly billed each warmup email as a credit. It doesn’t any more: warmup now comes with the plan, along with the domain the senders sit on.

Whose inbox sends the mail

This matters more than price, and it’s where the four split furthest.

FirstSales sends from mailboxes you connect, so if you leave, the domain and its history leave with you. Raechly buys a lookalike domain for you, sets it up and warms three senders on it. That domain is never shared with another customer or handed to the next one, so nobody else’s list touches its reputation. On Business you can connect your own inboxes as well.

Explee sends from inboxes it owns and has already warmed, which is why you can be live in an afternoon, where a new Raechly domain takes a few weeks to reach full volume. The reputation those inboxes build stays with Explee. We wrote up what that trade involves separately.

Gojiberry sends from your LinkedIn account, so the risk moves from your domain to your profile. LinkedIn doesn’t publish its limits, and a restricted account stops both the signals and the sends.

None of these is wrong. A two-week test of a new market is a fine use of someone else’s inboxes. A channel you plan to run for years belongs on a domain you own, though still not your primary one.

How much the agent does without asking

Autonomy is what these products sell, and it’s also the most common complaint about them.

Explee sits at 3.5 from 43 reviews on Trustpilot as of October 2026, where reviewers describe campaigns that started before they approved the leads, and charges they didn’t expect. Gojiberry does better on Trustpilot at 4.4 from 97 reviews, but its complaints are about messages naming the wrong role or industry. FirstSales has too few independent reviews to judge.

Raechly’s autopilot writes one email per contact, and nothing in a campaign sends until someone has read the real emails and approved them. Template campaigns send exactly what you wrote. That’s slower than letting an agent run. It’s also how you find out the copy is wrong before 500 people do.

The numbers each vendor publishes

	Claim	What we could check
FirstSales	No placement rate on its site now (October 2026)	An 87% figure it used to show has gone
Explee	97% inbox rate, $1 to $20 per lead	A hands-on test spent $20 on 660 emails for 7 replies, 1 lead and 0 meetings
Raechly	No placement rate	We can’t measure yours for you

Instead of a percentage, Raechly refuses to let a sender send until its replies are provably being captured, and a warmup message only counts when its reply comes back. The fairest test of any of these tools is your own reply rate on your own list over two or three weeks.

What happens after someone says yes

The four split again once a reply arrives. Explee’s agent answers and qualifies replies and sends your booking link. FirstSales books meetings to your calendar. Gojiberry puts replies in an inbox for your team to take over; its FAQ says it doesn’t book meetings itself.

Raechly writes an answer to each interested reply or question, with your booking link when that’s the goal, and waits for you to edit and send it. Then it keeps going past the meeting. An interested reply opens a deal in the pipeline, and each stage can start its own follow-up sequence. If your sale ends at a booked call, that matters less. If it runs over several conversations, it’s the point.

Running it from your assistant

All four have an API, and three mention MCP. FirstSales’ MCP server, launched in August 2026, covers campaigns, lead lists and analytics. Gojiberry lists an MCP connection without saying what it exposes. Explee documents a REST API. Raechly puts every tool on MCP, so Claude or Cursor can order your sending domain, find the people, write a sequence, work the inbox and move a deal without opening a dashboard.

Which one to pick

• Testing a new market next week, with no list: Explee.
• Buyers who live on LinkedIn: Gojiberry, ideally alongside an email tool.
• An email-first AI SDR with lead finding built in: FirstSales.
• Senders set up for you on a domain nobody else uses, approval before anything sends, and a pipeline after: Raechly.
