Reply.io vs Salesloft
Reply.io
Best for teams that outgrow per-seat pricing $49/Salesloft
Best documented cost-based rate limit Quote onlyReply.io vs Salesloft is the self-serve end of sales engagement against the enterprise one, and the first difference is that only one of them will tell you what it costs. Reply.io publishes every slider position, including the point where per-seat billing stops and $159 a month buys unlimited users at 10,000 active contacts. Salesloft publishes nothing and routes you to a sales conversation. For a team under twenty people that is usually the end of the discussion, because the evaluation cost alone favors the vendor with a rate card.
Where they actually differ

Pick each one when
Reply.io
- You want a published price and a slider you can size yourself.
- Unlimited users above 10,000 active contacts, with no seat negotiation.
- LinkedIn and email in one sequence, and a trial that includes API access.
Salesloft
- Forecasting and deal management matter as much as the sequencing.
- A cost-per-minute API model suits an integration doing expensive queries.
- Procurement expects an enterprise contract rather than a card payment.
A sender's rate card is not the part that bites. Confirm the API is on the plan you intend to buy, then run one real sequence of 200 contacts through each on a mailbox you have already warmed, and compare what the API tells you afterwards: which replies it classifies, what it reports on a bounce, and whether the webhook arrives at all. None of that is on a pricing page.
What each one costs, tier by tier
Only one of these two publishes a rate card. Reply.io lists its tiers, and Salesloft quotes everything, so half of this comparison is a number you have to go and get. Every figure is read off the vendor's own pricing page, and the pages they came from are listed at the foot of this one.
| The short version | Reply.io | Salesloft |
|---|---|---|
| Cheapest paid plan | Email Volume, 1,000, $49 | Not published |
| Tiers published | 4 | None |
| Free tier | No free tier. 14-day trial with API access and 300 active contacts. | No free tier and no published price. |
| Unit cost at entry | Not sold by the unit | Not sold by the unit |
The cheapest paid plan is rarely the plan you end up on, because what moves you up a tier is usually volume rather than a feature, and the two cards below say what each side publishes and what it keeps off the page.
Reply.io
Reply.io publishes 4 tiers, none of them free, and the paid ladder runs from $49 to $210.
Email Volume, 1,000
- Unlimited mailboxes under fair usage, 25 at this tier
- Unlimited emails to active contacts
- 50 live data credits, 200 website visitor reveals
Email Volume, 10,000
- Unlimited users, no per-seat charge
- 250 mailboxes under the published ratio
- LinkedIn automation at $69 a month per account
Multichannel
- Unlimited active contacts
- 10 mailboxes annual, 5 monthly
- LinkedIn, calls, SMS and WhatsApp included
Agency Core
- Multiple client workspaces under one account
- Unlimited clients, users and mailboxes
- White label as an option
Salesloft
Salesloft publishes no price at all, so there is no rate card to put here. Everything is quoted, which means the number you get depends on what you ask for and on where in their quarter you ask it.
Get these in writing before you sign: the per-unit rate at your volume, the annual minimum, how many seats that price assumes, whether API access is included or an add-on. Without the first two you cannot compare this against anything else on this page.
What Reply.io and Salesloft cost at your volume
Put your own volume in. The model picks the cheapest published plan that covers it on each side, which is the question a rate card cannot answer and the one that decides the bill.
Reply.io
Priced per seat, so the bill moves with headcount rather than with volume.
Salesloft
Publishes no price, so there is nothing here to model and the lines below say what to ask for.
Plans are read from each vendor's own pricing page and the model picks the cheapest one that covers you, so these are list prices before any discount you negotiate and before annual billing, which most of these vendors discount. Salesloft publishes no price, so nothing is modeled there and the panel says what to ask for instead.
What a year costs at three volumes
The same plan-fit arithmetic as the model above, run out to a year, because an annual number is what a budget actually asks for. Reply.io is priced per seat, so that column does not move with volume. The figure shown is 3 seats for a year.
| A year at | Reply.io | Salesloft |
|---|---|---|
| 1,000 a month | $1,764 Email Volume, 1,000 | Quoted |
| 10,000 a month | $1,764 Email Volume, 1,000 | Quoted |
| 50,000 a month | $1,764 Email Volume, 1,000 | Quoted |
1 of the 2 providers here publish enough to be put in this table. These are list prices on the published plan that covers each volume, so they are the number before you negotiate and before annual billing, which most of these vendors discount by between a fifth and a half.
How this plays out once it is running
Where Salesloft earns its position is the shape of the platform: forecasting, deal management and conversation intelligence around the sequencing, which Reply.io does not attempt. Its rate limit model is also genuinely better designed, metering 600 units of cost a minute per team rather than counting requests, so a cheap read costs 1 and page 501 of a deep scan costs 30.
Reply.io instead runs two live API versions, v3 at 100 requests a minute and a deprecated v1 at 15,000 calls a month, and search results point at the old one. If you are building, that is the trap to avoid on Reply.io, and the reason to read Salesloft's documentation carefully before assuming a request budget.
What each one is genuinely good at
Not a feature list. These are the things that make somebody keep paying after the novelty has worn off, which is a different question from what the marketing page leads with.
Reply.io
Every slider position is published, including where seats stop mattering
Reply.io prices per user to 5,000 active contacts and then flat for unlimited users at 10,000, where $159 a month covers the whole team. You can find the point where your headcount stops being a line item before you talk to anyone, which on Salesloft is not possible at all.
The fair usage rule is a number, not a word
One mailbox per 40 active contacts, published in Reply.io's own support article. Everywhere else in this category unlimited is an adjective; here it is a ratio you can size a sending infrastructure against.
The API is on every plan and on the trial
Including the 14-day trial, which carries 300 active contacts. v3 allows 100 requests a minute, 3,000 an hour and 150,000 a rolling week. Check the base path on anything inherited, because the deprecated v1 and v2 are still live at a 43-fold lower allowance of 15,000 calls a month.
Salesloft
An unusually precise API for a product with no published price
A budget of 600 cost a minute per integrated team, with a published cost for every endpoint. Most quote-only vendors document neither. Salesloft documents the metering in more detail than several vendors who publish their rate cards.
The product around the sequencer is the purchase
Forecasting, conversation intelligence and a defined process a manager owns. Reply.io sequences; Salesloft is bought by organizations that need the management layer, and comparing the two on sequencing alone misses what the money is for.
Where each one falls down
Every provider on this site has a case it handles badly, and the people who find out are the ones who bought it for that case. These are the ones worth knowing before you sign rather than after.
Reply.io
The pricing changes shape rather than scaling
Per user to 5,000 active contacts, then flat at 10,000. Two seats already cost more on the smaller plan than one does, so a team growing from one person to three crosses a cliff that has nothing to do with how much mail it sends.
LinkedIn is $69 a month per connected account
On top of the plan. For three reps running multichannel that is $207 before any email goes out, and it is easy to miss when the headline plan price is what gets compared.
Two live API versions 43 times apart
v3 allows 150,000 calls a rolling week; the deprecated v1 and v2 allow 15,000 a month with a ten second floor between calls, and they are still working at the host search results favor. An inherited integration on the wrong base path will look inexplicably slow.
Salesloft
Nothing about the price is public
The pricing page is titled Talk to Sales and contains a form. There is no seat price, no tier list and no published allowance, so the evaluation cost of finding out is itself part of what you are comparing.
The budget is the whole team's, not your integration's
Six hundred cost a minute applies per integrated team rather than per integration, so every tool connected to that team draws on the same allowance. Your backfill competes with whatever else somebody connected.
Deep paging costs thirty times the normal rate, and the costs can change
A request with a page parameter above 500 costs 30 of your 600 instead of 1, so a naive backfill exhausts the team budget in a couple of minutes. Salesloft also states that it can change the cost of an existing endpoint at any time, because a cost change does not break a contract.
Using Reply.io and Salesloft together
A two-way comparison assumes the answer is one of them. On this pairing it often is not, and the arrangement below is what teams actually end up running.
These overlap almost completely, so running both is a migration state rather than a design, and it is usually an enterprise rollout that has not finished replacing what a growth team bought first.
If you are in that state, the thing to watch is the Salesloft side of the budget. Six hundred cost a minute is shared across every integration on the team, and a sync keeping Reply.io in step is one more consumer of it. Page in small increments and never past page 500, because that is where the thirtyfold charge starts.
If the destination is Salesloft, get the Reply.io export done while the plan is still live, and keep a copy of the sequence definitions. Migrating the contacts is easy and migrating the logic is the part people underestimate.
Reply.io or Salesloft, for you
Four questions, answered from the same records as the rest of this page. Nothing is sent anywhere and there is no result to email yourself.
Each answer leans one way. The recommendation appears here once you have picked at least two.
A tool like this can only weigh what is on the page. It does not know your segment, and the one test that does is the bake-off further down: real rows, cheapest entry on each side, spend divided by survivors.
Where an answer leans on a certification or an integration, it means that vendor publishes it on the pages this directory read, which is not the same as the other one lacking it. The sources are listed at the foot of the page.
Where the data comes from, and what you may do with it
The question that arrives late and expensively is not how good the data is, it is who is allowed to hold it. These are the fields each one returns, the coverage it claims and the compliance it publishes.
| Provider | Fields returned | Coverage | Compliance | Redistribution |
|---|---|---|---|---|
| Reply.io | Work email, LinkedIn profile, CRM records | Global | GDPR DPA | Not stated |
| Salesloft | CRM records, Work email, Job changes | Global | GDPR DPA SOC 2 Type II | Not stated |
None of these states a redistribution position on its pricing or docs pages. Internally that never matters. Put the rows in something your customers can see and it becomes the question your legal team asks first.
Two practical notes that apply to every provider on this page. A compliance badge describes the vendor, not your use of it, so a GDPR DPA does not give you a lawful basis for the outreach you send. And every one of these vendors runs its own opt-out, which means a person who asks you to delete their record has to be removed from your copy as well as from theirs.
Moving between Reply.io and Salesloft
Most readers of this page are already on one of these two. A swap is four hours of code and a month of watching, and the order below is the one that catches the expensive mistakes while they are still free.
Measure the thing you are about to lose
Run 500 rows you already have through Reply.io and record the match rate, the fields that came back populated and the cost. Without that number a migration cannot be judged, because every provider looks cheaper per unit than the one you are paying for today.
Check the fields, not the field count
Salesloft does not return LinkedIn profile, which Reply.io does. If anything downstream reads linkedin profile, that is a change to your pipeline and not just to your vendor.
Rewrite the auth and the limits, in that order
Reply.io authenticates with bearer token on v3. A team Master API Key can impersonate a user. Salesloft uses OAuth 2.0, or an API key for a single team.
The limits are the part that bites later. Reply.io rate: v3: 100 req/min, 3,000/hour, 150,000 per rolling 7 days, per user. v1 and v2: 15,000 a month.
Salesloft rate: 600 cost a minute per team. Endpoint costs vary and Salesloft can change them. A loop tuned to the first will either crawl or get throttled on the second.
Run both for one billing cycle
Keep the old key live and route a slice of real traffic to the new one. A month is the shortest honest test, because credit expiry, rollover and the overage rate only show up at renewal and those are where the surprises live.
Cancel on the renewal date, not before
Credits on most of these plans do not survive a downgrade. Check what happens to the balance you have already paid for, and time the switch so you are not buying the same records twice.
The step people skip is the first one, and it is the only one that cannot be done after the fact. Once the old key is off you have nothing to compare the new match rate against, so a provider that is quietly worse on your segment looks like a provider that is fine.
The wider field for both
A two-way comparison assumes the answer is one of these two. Often it is not, and the reason you are comparing them at all points somewhere else entirely: Reply.io alternatives and Salesloft alternatives both start from the reason people leave.

Reply.io and Salesloft, answered
Read from the same records that drive the table above.
Is Reply.io or Salesloft cheaper?
Salesloft does not publish a price at any tier, so the two cannot be compared on cost. Reply.io starts at $49/user/mo, which is as far as the comparison goes.
Can I try Reply.io and Salesloft for free?
Reply.io: No free tier. 14-day trial with API access and 300 active contacts. Salesloft: No free tier and no published price.
What are the rate limits on Reply.io and Salesloft?
Reply.io: v3: 100 req/min, 3,000/hour, 150,000 per rolling 7 days, per user. v1 and v2: 15,000 a month. Salesloft: 600 cost a minute per team. Endpoint costs vary and Salesloft can change them.
Do Reply.io and Salesloft both have MCP servers?
Both do. Reply.io: https://mcp.reply.io/. Salesloft: https://mcp.salesloft.com/sse.
Which is better, Reply.io or Salesloft?
Reply.io vs Salesloft is the self-serve end of sales engagement against the enterprise one, and the first difference is that only one of them will tell you what it costs. Reply.io publishes every slider position, including the point where per-seat billing stops and $159 a month buys unlimited users at 10,000 active contacts.
What are the downsides of Reply.io and Salesloft?
Measured against each other rather than in general. Reply.io: there is no free tier, only a trial, so test your own list inside its limits before paying. Salesloft: there is no free tier, so you cannot measure your own match rate before paying; nothing is priced publicly, so every comparison starts with a sales call.
Can you use Reply.io and Salesloft together?
These overlap almost completely, so running both is a migration state rather than a design, and it is usually an enterprise rollout that has not finished replacing what a growth team bought first.
Can I migrate from Reply.io to Salesloft without losing data?
Not without losing a field. Salesloft does not return LinkedIn profile, which Reply.io does, so anything downstream that reads it has to change. Either way, measure your match rate on 500 rows before you switch, because that number is the one you cannot recover afterwards.
