Another email is not the quickest way to reach a decision maker. It is a number that they actually answer. The issue isn’t the channel. It is the data. Most sales reps have not verified direct dials to the individuals they wish to reach, so default to email where they compete as a thread in an inbox that registers an average open/response rate of 4-5% (circa 2026).
SignalHire‘s Phone Number Finder solves that. It retrieves verified mobile and direct dial numbers of professionals from 850M+ profiles through the browser extension on LinkedIn or bulk CSV upload. The outcome is a reachable number for an executive in less than five seconds.
Two data points frame why this matters right now:
- 57% of C-level executives prefer phone as their first contact channel, according to Gartner benchmark study covering 488 B2B buyers. will agree to meet with that caller, according to RAIN Group’s benchmark study involving 488 B2B buyers. The channel is not the barrier. It is finding the number. More than a few sales reps never get round to making the call because they fail to find a verified direct dial in time to do something before the opportunity is closed.
- 82% of B2B buyers will agree to meet with that caller, according to RAIN Group’s benchmark study involving 488 B2B buyers. The channel is not the barrier. It is finding the number. More than a few sales reps never get round to making the call because they fail to find a verified direct dial in time to do something before the opportunity is closed.
Your competitor is writing their third follow-up email in a row to the same VP. You have their mobile number. This article explains that difference.
Why Do Direct Phone Numbers Give You a Competitive Edge?
Because decision makers screen email but answer their phone. The most challenging channel to reach them through is, naturally, what everybody’s on. The version they use is the one that virtually no rep will have access to.
In 2026, B2B inboxes are clogged. Cold email response rates decreased from 8.5% in 2019 to about 4-5% now. The average cold email is vying with dozens of identical outreach efforts from vendors targeting the same account. Spam filters have grown sharper. Buyers have grown more selective. The return on email-only sales motion approaches zero as for every additional sender that enters the market.
The same filters available in the SignalHire database — job title, industry, company revenue, department — apply directly to Lead Tracker results, separating the accounts worth same-day outreach from general browsing noise.
For RevOps teams routing identified visitor data programmatically into Salesforce or HubSpot, the SignalHire API handles the transfer without a manual CSV step between identification and CRM record creation.
Phone is different. Nothing cuts through more noise than a direct call to a decision-maker — it trumps every inbox filter, every assistant and delete-on-sight habit trained from years of mass outreach. It generates a live dialogue that email simply cannot. Objections come up and are handled in real time. Rapport forms in seconds. The buying signal a rep can glean in a three-minute call would take weeks of email follow-up to approach.
The gatekeeper problem makes the advantage even worse. Gatekeepers are the first line of defence, blocking an estimated 70-80% of general office line calls from reaching a decision maker. A verify direct mobile number cuts all of that out. The call goes to the person. Not the main line. Not a receptionist. Not voicemail box number seven.
Speed is the third edge. Research consistently shows that up to 50% of competitive B2B deals go to the first vendor to engage. A rep who gets a decision-maker’s direct line and dials it minutes after whatever triggered the event, a funding round, a role-change, an incursion into their pricing page enjoys a structural speed advantage over teams blasting out emails and waiting 48 hours for replies they never receive.
Who Counts as a Decision-Maker and Why Does That Distinction Matter?
A decision-maker carries buying authority, budget approval or veto power. Hitting them directly shortens sales cycles and removes the danger of a deal dying in committee.
Not all contacts within a target account deserve to be dials. If an SDR is wasting time looking up the phone numbers of low-level individual contributors, they are NOT executing on a phone-first strategy. This is a busy-work strategy with additional steps.
There are four different types of enterprise B2B decision-makers. “[Effective] Budget Authority: Economic buyers have authority over the final budget. They will approve the vendor, sign the contract, and decide on the deal size. Technical buyers assess compatibility, security and integration. They can scuttle deals even without final approval authority. User champions promote the product internally. They speed up deals, but they seldom close them independently. At all levels, blockers exist but are seldom called that until a deal dies.
Measuring the direct number for a monetary purchaser also shifts the entire deal dynamic. It eliminates the risk that your champion’s internal advocacy would be deprioritized or lost. It provides the AE direct access to the person who signs off on closing the contract. According to research by Gartner, these buying groups average six to ten decision makers for deals greater than $50,000 ACV. So that’s why many direct dials are important not just one.
The competitive angle in the article’s title is literal. However, when your rep dials a VP of Sales on their direct mobile two hours after a competitor’s third follow-up email has been left unread, your conversation begins from an entirely different place. The VP picks up. The context is established. The only person that called was the rep. That is not an accident. It is a data advantage.
How Does SignalHire Phone Finder Work?
Upload a name, LinkedIn URL, or email. SignalHire returns a verified direct number in real time. On LinkedIn, the browser extension delivers it in under five seconds without leaving the profile.
SignalHire’s Phone Number Finder operates through three distinct workflows depending on the scale and starting point of the search.
The browser extension is the quickest route for researching individual prospects. Having opened a LinkedIn profile, you click the SignalHire extension icon, and within seconds a contact card pops up with verified email addresses and direct phone numbers. No LinkedIn connection is required. No tab switching is needed. The number is sitting there, poised to be dialed. SignalHire offers coverage for about 85% of LinkedIn profiles and phone accuracy up to 80% on returned numbers, verified in real time at the point of search.
List scale enrichment is managed by the bulk phone finder. Upload a CSV of names and companies, LinkedIn URLs or email addresses. SignalHire cross-references every record with its extensive 850M+ entry database and gives direct dials for every profile matched. For a prospecting list comprising 500 target accounts, that is — in minutes not days of manual research, a verified phone number for the right contact at each company.
SignalHire’s Phone Number Finder operates through three distinct workflows depending on the scale and starting point of the search: browser extension, bulk CSV upload, and phone lookup by email.
Phone lookup by email reverses the process. If you have someone’s email address, but do not have their direct number, just place that e-mail on SignalHire to get their complete contact profile along with phone. This is especially useful when enriching inbound leads who converted on some demo request form with a work email but no phone. You fill that data gap prior to the AE picking up the account.
Phone data is all checked at search, not entry into a database. That distinction matters. A number that was correct six months ago may have been reassigned since then. SignalHire hides what was true at the last known time in which that record was updated. It reflects what is correct at this moment.
The same extension that surfaces direct dials also returns verified emails in the same single reveal, making it possible to extract email and phone from LinkedIn in one click without switching tools or tabs.
Which Method of Finding a Phone Number Works Best?
The browser extension on LinkedIn is fastest for individual outreach. The bulk CSV finder is most efficient for list-scale campaigns. Manual research and static lists consistently underperform both.
| Method | Speed | Accuracy | Scale |
| SignalHire Browser Extension (LinkedIn) | Under 5 seconds | Up to 80% | One click per profile |
| SignalHire Bulk Phone Finder (CSV) | Minutes for 1,000+ | Up to 80% | Up to 1,000 per batch |
| Phone lookup by email | Instant | High | One-to-one or bulk |
| Manual research (directories, Google) | 15-45 minutes | Low-medium | Very limited |
| Buying a static list | Same day | Often under 50% | High volume, low precision |
That accuracy gap, between known tools and static lists, is the most operationally important number in that table. A purchased list from a data vendor typically has accuracy rates below 50%, so there’s about a one in two chance that when your team dials, nobody will pick up and no connection will be made to the intended contact. That is not a volume problem. Volume does not fix this, however; it is a data quality issue.
The time cost is multiplied by manual research. And a rep who spends half an hour tracking down one prospect’s phone number is a rep who isn’t on the phones. At scale, that research overhead is the same as adding another SDR headcount focused solely on data work and no selling. The browser extension cuts that 30-minute research task down to less than five seconds per contact. Given a team making 50 targeted calls every week, the collective productivity variance is noticeable.
Use the bulk finder when driving account-based campaigns against a named account list. Submit the complete list, get back enriched phone information for the matches and direct to dialing sequence. No manual lookup per contact. There is no research bottleneck between prospecting and outreach.
How Do You Find Phone Numbers for C-Suite Executives Specifically?
Start with LinkedIn, run the extension, verify in real time. If a direct number is not returned, try phone lookup by email. C-suite contacts have higher data coverage in SignalHire because of their public professional footprint.
Ironically, it is far easier to find phone numbers for C-level buyers than mid-level managers. They have more fully filled-out and publicly-maintained professional profiles, more consistently linked across platforms. A CEO or VP has a strong presence on LinkedIn, often on pages company, sometimes in mentions press. Those signals are aggregated into SignalHire’s database, which produces more extensive contact profiles for senior executives than for the individual contributor with little public presence.
The approach is direct. Visit the executive’s LinkedIn profile. Activate the SignalHire extension. Check the returned contact card for a cell or direct number. If the extension connects to a corporate main line versus a direct number, also try phone lookup by email using the executive’s known work email. Because the reverse lookup makes an additional pass, it often finds direct mobile numbers that were not picked up during the extension’s initial sweep.
For accounts where the target executive is not findable by LinkedIn or email alone, SignalHire’s database supports search by name plus company combination. Type the executive’s name, add the company, and the platform returns available contact data from across its 850M+ profile index. The search does not require a LinkedIn URL or existing email address to produce results.
After you have the number, however, how you approach outreach matters just as much as the data itself. While 57% of C-suite buyers prefer to be contacted by phone, if unprepared callers try to reach out first, they won’t let it go. A cold call to a CFO that starts with a boilerplate script is worse than no call. That difference is preparation, the 82% of buyers who accept meetings from a well-prepared caller, and the balance that would not call back.

How Do You Build a Phone-First Outreach Workflow?
Three steps: find the number, verify it in real time, call within the same session. Add email as a follow-up layer, not a replacement. The call comes first.
A phone-first outreach workflow is not a cold calling program. It’s a sequenced multi-touch strategy; the verified direct call is first and highest-priority touch, with email and LinkedIn following as additional channels.
Step one is list preparation. One way is to know the decision-makers in your target accounts by title and seniority. And then export them or if you want, create the list inside SignalHire database filtered by company, industry and job title. Bulk phone enrichment runs before the calling session begins, attaching verified direct dials of each contact.
The SignalHire browser extension surfaces a verified email and direct phone for any identified visitor’s LinkedIn profile in under five seconds, without leaving the SignalHire dashboard.
Step two is the call. Dial from a verified number the same day the prospect is enriched. If they answer, the conversation starts with context: reference a trigger event, a pricing page visit surfaced by SignalHire Lead Tracker, a funding round, a job change, or a relevant industry development. If they do not answer, leave a voicemail under 20 seconds and follow up with an email that references the call. Research shows following up within one to two hours of a voicemail generates significantly higher reply rates than a standalone cold email.
Step three is sequence completion. (If no response, after the call and email add a LinkedIn touch mentioning earlier outreach on day three. Then another attempt to call on the fifth or sixth day. Then a last email around day eight or nine. Reaching a B2B prospect requires an average of eight contact attempts. Most reps stop at three. Teams that include a verified direct dial as the first touch and run full 8-touch sequences, beat out teams running nothing but email with zero phone layer every time.
For teams wanting to automate the email follow-up layer after the initial call, SignalHire Email Sequences handles scheduled follow-up cadences tied to the same contact. The phone starts the relationship. The sequence maintains it.
For teams that want to extend the phone-first approach into a full multi-channel system, the complete guide to outreach contact discovery covers every workflow stage from first search to first reply.
What Results Should You Expect From a Phone-First Approach?
Higher connect rates on direct dials than on main lines, higher meeting conversion than email-only sequences, and shorter sales cycles when decision-makers are reached directly rather than through intermediaries.
The overall performance lift from phone-first outreach comes in 3 areas: Connection rate, meeting conversion, and deal velocity.
For identified visitors where the extension returns a corporate domain but no direct address, the SignalHire email finder closes the gap by searching for a verified personal or direct work email tied to the profile.
The most immediate improvement is the connection rate. An verified direct mobile skips the main line, the receptionist and corporate voicemail system — all with a single number. Teams that use verified direct dials achieve material connection rates compared to teams dialing main company lines. The gatekeeper problem that stymies roughly 70-80% of office calls vanishes when your rep is dialing a personal cell number.
Call concludes a conversation that email has never, which is why meeting conversion is higher. The call-to-meeting conversion rate is 6.7%-of conversations which connect with a decision maker on a direct dial, compared to cold email that has a response rate of only 4-5% given on sent volume. Those numbers measure different things, but the underlying thesis is true: a connected phone conversation with an appropriate, prepared caller creates meetings at a ratio email sequences can never hope to achieve.
When we can go direct to the economic buyers, deal velocity increases. Deals where the AE knows the CFO’s mobile and can call directly with a question, or jump on to resolve a concern late in negotiation move faster than deals where everything queues through a champion’s email (to an entity that likely doesn’t feel like a champion) to the finance team. Direct access to the decision-maker eliminates communication silos that quietly extend enterprise sales cycles by weeks or months.
FAQs
How accurate is SignalHire’s Phone Number Finder?
SignalHire phone numbers are checked in real time at the name point of search, rather than at a historical database update. Returned numbers can be 80% accurate. If verification fails for a number, it is simply not returned. This protects against wasted dial time on disconnected or reassigned contacts.
Can I find phone numbers for LinkedIn contacts without being connected?
Yes. With the SignalHire browser extension, you can find confirmed contact information for any LinkedIn profile whether or not you are connected. The data does not require a first-degree connection, a LinkedIn Recruiter subscription, or lacking InMail credits.
What is the difference between a direct dial and a main company line?
A direct dial or direct mobile will ring directly to the person. A primary business number passes through a front desk, an automated pilot, or a generic department queue. Gatekeepers prevent an estimated 70-80% of calls from reaching the target contact on main company lines. A direct mobile has no intermediary/ gate keeper.
How do I find phone numbers for a list of 500 target contacts?
Upload the list as a CSV to SignalHire’s bulk phone finder. Include LinkedIn URLs, name-plus-company combinations, or email addresses as identifiers. SignalHire returns verified phone numbers for all matched profiles. The enriched file downloads as a CSV ready for import into your dialing tool or CRM.
Is calling a decision-maker on their mobile number acceptable in B2B sales?
Yes, but only when the call is topical, prepped and professional. 82% of B2B buyers are willing to meet with a well-researched caller who reached them directly. There is an assumption that the rep has done their research and can express relevancy within the first 15 seconds. There’s no phone call worse than a generic cold script on a direct mobile. And it’s a tailored, context-rich opener that converts.
How does phone outreach work alongside email sequences?
Phone is the initial contact as well as the most significant touch. Email comes after the call to remind and reinforce contextual awareness, making a written reminder for buyers that are always on the go. A third layer of channel is added with LinkedIn. When ran in a structured roll, and verified phone data is used as the anchor, running all three channels delivers measurably better results than any single-channel approach.
