--- title: "Outreach vs Salesloft: which one, and why" description: "Outreach and Salesloft compared on unit cost, billing model, data returned, license and MCP support. Verified pricing, October 2026." url: https://frontal.so/gtm-apis/compare/outreach-vs-salesloft updated: 2026-11-12 --- Head to head · Verified 24 Oct 2026 # Outreach vs *Salesloft* ## Outreach A 42-tool MCP server behind OAuth 2.1 and dynamic client registration Quote only vs ## Salesloft Best documented cost-based rate limit Quote only Short answer Outreach vs Salesloft is a choice between two enterprise platforms that both decline to publish a price, so the API is one of the few things you can compare before a sales call. Outreach is the stronger agent surface: OAuth-scoped REST, warehouse export and an MCP server carrying 42 tools. Salesloft is the more predictable integration target, with a documented 600 cost a minute and a published cost per endpoint, plus an API key option for a single team. Neither has a cost model here, because neither has a rate card. Side by side ## Where they actually differ Every value comes from the same record that drives the [Sending APIs](https://frontal.so/gtm-apis/sending-apis) listing, so this table cannot disagree with the cards. Accented tags are data one provider returns and the other does not. | Compare | [Outreach](https://frontal.so/gtm-apis/sending-apis/outreach-api-review) | [Salesloft](https://frontal.so/gtm-apis/sending-apis/salesloft-api-review) | | --- | --- | --- | | What sets it apart | Quote only, OAuth only, and 42 MCP tools | A cost budget per minute, and deep paging costs 30 times a call | | Entry price | Quote only | Quote only | | Unit cost | Not sold by the unit | Not sold by the unit | | Billing model | Per seat Credit packs | Per seat Subscription | | Free tier | No free tier and no published trial. | No free tier and no published price. | | GTM motion covered | Engage Sync | Engage Sync | | Data returned | Work email Mobile phone CRM records | CRM records Work email Job changes | | MCP server | Yes Hosted, 42 tools, OAuth 2.1 with DCR | Yes https://mcp.salesloft.com/sse | | Interfaces | REST API MCP server Webhooks Bulk or async | REST API MCP server Webhooks Bulk or async | | Auth | OAuth 2.0 with scoped tokens, or an S2S app token for server jobs.

The test that settles it A sender's rate card is not the part that bites, and none of what does is on a pricing page. 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. Afterwards, compare what the API tells you: which replies it classifies, what it reports on a bounce, and whether the webhook arrives at all. Neither offers a self-serve trial, so make a sandbox with API access a condition of the evaluation. Plan by plan ## What each one costs, tier by tier Neither of these publishes a plan-by-plan rate card, and that is itself the finding: at this end of the market the price is whatever the quote says. What follows is what each one does publish, and what to ask for. 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 | Outreach | Salesloft | | --- | --- | --- | | Cheapest paid plan with the API | Not published | Not published | | Tiers published | None | None | | Free tier | No free tier and no published trial. | 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. ### Outreach Outreach 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. ### 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. In practice ## How this plays out once it is running Neither vendor publishes a seat price, so this page has no cost model and no year at three volumes. What each one does publish differs. Outreach names four Amplify plans, Core, Essentials, Plus and Pro, with 25,000, 10,000, 50,000 and 100,000 AI credits respectively, lists 250,000, 500,000 and 1,000,000 API calls on Core, Plus and Pro, and prices seat access and credit consumption on a quote. [Salesloft](https://frontal.so/gtm-apis/sending-apis/salesloft-api-review)'s pricing page is titled Talk to Sales and contains a form. The API documentation runs the other way. [Outreach](https://frontal.so/gtm-apis/sending-apis/outreach-api-review) publishes 10,000 requests an hour per user, with X-RateLimit headers on every response, and caps page size at 1,000 and offset at 10,000. Salesloft documents a budget of 600 cost a minute per team, a cost for every endpoint, and a page above 500 costing 30 of that 600 rather than 1. One meters each user against a flat ceiling, the other meters the whole team against a priced budget. Strengths ## What each one is genuinely good at These are the things that keep somebody paying after the first month, which is a different question from what the marketing page leads with. ### Outreach #### An MCP server with 42 OAuth-scoped tools Forty-two tools behind OAuth 2.1 with PKCE and dynamic client registration. If an agent is meant to work inside the sales engagement platform rather than through a REST client you wrote, this is the clearest reason to pick Outreach. Salesloft's server is a read-only beta of 13 tools, so an agent can look through it but not act. #### Warehouse export rather than paging Data Sharing through Snowflake or Delta Sharing is sold as an add-on, so an organization with a warehouse can read Outreach data there instead of pulling it a page at a time. Against Salesloft's charge of 30 cost for deep pages, that is a different and better extraction story. #### OAuth scopes per application and per token JSON:API 1.0 behind OAuth 2.0, with scopes granted per application and per token. It is more ceremony than a key and it is the right security model for a platform touching every rep's pipeline, which procurement reviews tend to ask about. ### Salesloft #### A request budget you can do arithmetic with Six hundred cost a minute per integrated team, with each endpoint's cost published. Outreach publishes a flat 10,000 requests an hour per user, which is a ceiling rather than a price list, so Salesloft is the one of the two where you can see what each call spends before it runs. #### An API key for a single team Alongside OAuth 2.0 for applications. A team building one internal integration can skip the registration flow, where Outreach requires an OAuth application for every integration with no key option. #### It documents how to stay inside the budget The recommended pattern is a cursor poller on updated\_at rather than offset paging, and the docs explain why: past page 500 a request costs 30 rather than 1. Knowing the trap in advance is worth more than a higher ceiling you discover by hitting it. Limits ## 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. ### Outreach #### One flat ceiling per user, with exceptions Ten thousand requests an hour per user, while bulk endpoints and Kaia follow their own rules: Kaia recordings and transcripts allow 3 calls a second and 6,000 a day for the whole org. Page size caps at 1,000 and offset at 10,000, so a backfill is designed around pagination as much as around the hourly number. #### No API key, for any integration Server jobs can use an S2S token signed with your own key pair, but it still needs a registered app, an org admin install and a narrower set of scopes than OAuth. For a two-person ops team wiring up one sync, that is a disproportionate amount of setup for the job. #### AI credits are a second meter Seats buy access and AI work consumes credits, with extra packs sold on top. A team adopting the agentic features can outgrow its allowance before its seat count changes, and none of it is priced in public. ### Salesloft #### The budget is shared across the whole team Every integration connected to that team draws on the same 600 cost a minute. A tool somebody else installed can starve your sync, and the documented remedy is to contact Salesloft. #### Endpoint costs can change without notice Salesloft states it can change the cost of an existing endpoint at any time, because a cost change does not deprecate functionality. An integration sized against today's costs has no protection against tomorrow's. #### Nothing about the price is public No seat price, no tier names and no statement of whether API access costs extra. Outreach at least publishes its plan structure; Salesloft publishes a form. Both ## Using Outreach and Salesloft together Teams comparing these two often end up running both, and the arrangement below is the one they settle on. These are rarely run together, because they are bought by the same person for the same job: the process layer around a sales team, with sequencing inside it. Two platforms on one sales team means two sources of activity truth and reps who use neither properly. The legitimate overlap is a migration. If you are moving between them at renewal, the extraction is where the two API designs matter most. Pull Outreach data through Data Sharing if you have it rather than paging, and load Salesloft with a paced writer that stays well inside 600 cost a minute, since the target team's budget is shared with everything else already connected. If you only buy one, let the agent question decide it. A team planning to put an agent inside the sales engagement platform has one real option here, Outreach, and a team that values a budget it can calculate will find Salesloft the easier system to build against. Decide ## Outreach or Salesloft, for you Two questions, answered from the same records as the rest of this page. Nothing is sent anywhere and there is no result to email yourself. Do you need mobile phone? What does finance want to see? Answer the questions above 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 workload, and the one test that does is the bake-off on this page: your own rows, queries or records, run on the cheapest entry each side offers. 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. Provenance ## Where the data comes from, and what you may do with it The question that arrives late and expensively is who is allowed to hold the data. These are the fields each one returns, the coverage it claims and the compliance it publishes. | Provider | Fields returned | Coverage | Compliance | Redistribution | | --- | --- | --- | --- | --- | | [Outreach](https://frontal.so/gtm-apis/sending-apis/outreach-api-review) | Work email, Mobile phone, CRM records | Global | GDPR DPA SOC 2 Type II | Not stated | | [Salesloft](https://frontal.so/gtm-apis/sending-apis/salesloft-api-review) | 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 rather than 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. Migration ## Moving between Outreach and Salesloft Most readers of this page are already on one of these two, and the order below catches the expensive mistakes while they are still free. 01 ### Measure the thing you are about to lose Record last month's sends, replies and bounces as Outreach's API reports them, per mailbox and per account. Reputation does not move with the vendor, so this is the number the new sender has to reach on the same domains. 02 ### Check which fields change Salesloft does not return mobile phone, which Outreach does. If anything downstream reads that field, the switch changes your pipeline as well as your vendor. 03 ### Rewrite the auth and the limits, in that order Outreach authenticates with OAuth 2.0 with scoped tokens, or an S2S app token for server jobs. No API key option. Salesloft uses OAuth 2.0, or an API key for a single team. The limits are the part that bites later. Outreach's limits: 10,000 requests an hour per user. Page size caps at 1,000 and offset at 10,000. Salesloft's limits: 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. 04 ### 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. 05 ### Cancel on the renewal date 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 one against, so a provider that is quietly worse on your workload looks like a provider that is fine.

FAQ ## Outreach and Salesloft, answered Read from the same records that drive the table above. **Is Outreach or Salesloft cheaper?** Neither publishes a price, so there is no honest answer to this one. Both quote, and the evaluation cost of finding out is part of what you are comparing. **Can I try Outreach and Salesloft for free?** Outreach: No free tier and no published trial. Salesloft: No free tier and no published price. **What are the rate limits on Outreach and Salesloft?** Outreach: 10,000 requests an hour per user. Page size caps at 1,000 and offset at 10,000. Salesloft: 600 cost a minute per team. Endpoint costs vary and Salesloft can change them. **Do Outreach and Salesloft both have MCP servers?** Both do. Outreach: Hosted, 42 tools, OAuth 2.1 with DCR. Salesloft: https://mcp.salesloft.com/sse. **Which is better, Outreach or Salesloft?** Outreach vs Salesloft is a choice between two enterprise platforms that both decline to publish a price, so the API is one of the few things you can compare before a sales call. **What are the downsides of Outreach and Salesloft?** Outreach: one flat ceiling per user, with exceptions; no API key, for any integration; AI credits are a second meter. Salesloft: the budget is shared across the whole team; endpoint costs can change without notice; nothing about the price is public. The Limits section above has each one in full. **Can you use Outreach and Salesloft together?** These are rarely run together, because they are bought by the same person for the same job: the process layer around a sales team, with sequencing inside it. Two platforms on one sales team means two sources of activity truth and reps who use neither properly. **Can I migrate from Outreach to Salesloft without losing data?** Not without losing a field. Salesloft does not return mobile phone, which Outreach does, so anything downstream that reads it has to change. Either way, run one live sequence on a warmed mailbox through both before you switch.
