Coseek publishes this guide and is included in the shortlist. The comparisons use the providers' linked service pages and describe their scope, rather than independently ranking campaign results.
The shortlist
| Agency | Consider it when you need | Key scope distinction |
|---|---|---|
| Coseek | Research, calling, rep management and qualified handoff together. | A phone-led campaign, with your team handling the deeper sales work. |
| Quick Cold Calls | A defined amount of calling against a list you supply. | 250 or 500 monthly call activities, counted as dial attempts. |
| Superhuman Prospecting | US-based callers with calls-only or broader SDR options. | Flex keeps list building separate; Premium adds lists, email and nurturing. |
| Sales Focus | Cold calling with research, scripts, qualification and coaching. | A tailored service whose included responsibilities belong in the proposal. |
| SalesHive | Managed SDRs with phone-only or phone-plus-email options. | US-based or offshore teams; platform-only service is a separate choice. |
| Callbox | Coordinated calling, email and LinkedIn across target markets. | Regional coverage, meeting briefs, reporting and CRM synchronization. |
| SalesRoads | Appointment setting with preparation, coaching and sales operations. | Fractional or full-SDR programs using calls and email. |
If your team already supplies good lists, messaging and caller management, an activity package may cover the missing capacity. If those jobs need an owner too, a managed campaign is the more relevant purchase. Multichannel services add value when you want the same provider coordinating phone, email and other channels.
Coseek: a managed cold-calling team
Coseek is a fit when you want a cold-calling campaign run for you, from finding suitable accounts to handing over qualified sales conversations.
We research the market, select the people to call, prepare their contact details and account context, and write the script. Your campaign has an assigned sales rep supported by our research and sales management team. The manager reviews selected calls and practises with the rep each working day. Your team brings product knowledge, exclusions and sales feedback, then handles the meetings and deeper sales work.
We typically begin with a four-week validation sprint, with preparation before 20 calling days. Ongoing delivery is month to month. We run campaigns in the US and UK. For other markets, get in touch and we can discuss your campaign.
The free cold-call game plan shows the account and buyer targeting we recommend, the campaign approach and a complete script. No meeting is required. Coseek focuses on calling, with responsive email and selective LinkedIn follow-up after engagement or a request. A broader cold-email program or outsourced closing requires a provider with that scope.
Quick Cold Calls: a small calling package
Quick Cold Calls is worth considering when you have a contact list and want a defined amount of calling activity. Its Starter options list 250 or 500 monthly call activities, with scripting, account management, reporting and appointment confirmation. You supply the contact list. Quick Cold Calls service and package details
Its activity allowance counts dials, including voicemail and unanswered attempts. That makes it a purchase of calling activity, with the quality and coverage of your supplied list affecting whom the team can reach.
Superhuman Prospecting: US-based callers
Superhuman Prospecting offers calls-only Flex subscriptions and broader Premium SDR bundles using US-based callers. Flex includes scripting, a strategist and reporting, with the contact list supplied or purchased separately. Premium adds list building, cold email and nurturing. Superhuman Prospecting service options
The useful choice is how much work to combine with calling. Flex suits a team supplying its own contacts; Premium brings more of the data and follow-up work into the service. Setup and CRM integration can add to the cost, so the selected option matters when comparing quotes.
Sales Focus: cold calling with sales support
Sales Focus describes cold calling supported by targeted-list research, script development, qualification and appointment scheduling. Its process includes call monitoring, coaching and reporting. Sales Focus cold-calling services
That scope makes it relevant when you want calling supported by research and sales management. The proposal should identify the people assigned, the work included and the qualification standard your sales team will receive.
SalesHive: managed SDRs or platform only
SalesHive offers managed SDR programs with phone-only or phone-plus-email options, and US-based or offshore teams. Its pricing page lists a strategist, list building, data, calling tools, call review and coaching within the service. It also offers the platform separately for teams running their own work. SalesHive plans and service options
The managed service is relevant when you want the team and tools together, with a choice of channel mix. Platform-only is a software purchase for your own operators. A phone-focused buyer can consider the phone-only service without assuming email must be included.
Callbox: coordinated phone, email and LinkedIn
Callbox combines account targeting, calling, email and LinkedIn with an appointment-setting team. Its service page describes caller preparation, meeting qualification, briefing notes, reporting and CRM synchronization, with coverage across multiple regions. Callbox appointment-setting services
That wider scope is useful when several channels or regions belong in the campaign. The proposal needs to make the countries, languages, buyer groups and campaign commitment specific to your work.
SalesRoads: fractional or full-SDR appointment setting
SalesRoads describes a program built around a sales playbook, list preparation, SDR training, calling and email, with coaching and sales-operations support. Its service page offers fractional and full-SDR appointment-setting options. SalesRoads appointment-setting programs
It is relevant when you want appointment setting with a defined preparation process and ongoing caller support. Fractional and full-SDR programs provide different amounts of capacity, so the proposal should state the work assigned to your campaign and when calling starts.
See the work your buyers will experience
A proposed script shows how the agency understands your offer: whom it would call, why those people might care and what it would ask them. A relevant recording shows something different: whether the caller listens, follows an answer and earns a useful next step. Ask for both when comparing the teams you are seriously considering.
Client stories and reviews are most useful with the campaign context attached. The product sold, buyer roles, campaign period and meaning of the reported result matter. Experience in your industry can be valuable even when the offer differs, but it does not establish that the same result will follow for your business.
Management also needs to be concrete. The proposal should name who is responsible for the caller's performance, who reviews conversations and how your team reaches that person when meetings miss the mark. A client reference can help explain how the agency responds when a campaign needs work. Your sales leader should know which responsibilities remain with them before buying a managed service.
An internal SDR can be the right choice when you want to build and own the function. That choice includes research, data, tools, management and coaching alongside the hire. An agency is useful when you want some or all of those jobs handled for you.
What makes a meeting qualified?
The qualification standard should explain what the caller must establish about fit, need and interest before booking. A sample handoff lets you see whether your salesperson would arrive knowing why the buyer agreed to meet.
At Coseek, we agree the relevant account and role criteria, plus the problem, current process, timing, use case or equivalent evidence the call must capture. The buyer accepts the purpose of the next step. We confirm a specific attendee, date and time and send the invite. Your team receives the context behind the meeting and the questions or needs raised on the call.
Booked meetings, held meetings and sales-accepted opportunities are different stages. Keeping them separate makes reports useful and shows where your team needs to follow up. Feedback from those conversations should inform the next round of account selection, messaging and qualification.
How much of the initial term includes calling?
Research, list building and caller preparation should produce a campaign ready to run. The proposal should also state when billing starts, when calling starts and when the initial commitment ends. Those dates show how much preparation and active calling you are buying.
Coseek's typical four-week validation sprint includes preparation plus 20 calling days. The research, list, script and rep preparation happen before those calling days begin. We then assess the people reached, conversations and meeting fit with your team, and recommend whether to continue, change the campaign or stop, based on what buyers said.
A change of market or offer may require a new list, script and rep preparation. A useful initial plan makes the first audience and reason to call clear enough to assess. For published provider prices and the work behind them, see the cold-calling agency cost guide.
