## Research

First-party studies on LinkedIn outreach, content and B2B data: 196,696 matured connection requests sent between January 2025 and July 2026, 251 LinkedIn posts published between November 2025 and August 2026, and a 2,037,030-contact B2B database audited in full. Every study states its sample, denominators and limitations. Figures are free to quote with attribution. Earlier studies cite their own frozen 180,155-request cohort; each study names its snapshot.

- [Research hub](https://www.reachium.io/research)
- [The Best Day to Send LinkedIn Connection Requests Does Not Exist](https://www.reachium.io/research/best-day-to-send-linkedin-connection-requests): Across 196,696 LinkedIn connection requests given at least 30 days to mature, acceptance by day of week ranged from 26.38% to 28.24%, a spread of 1.86 points, and weekend requests were accepted within 0.27 points of weekday requests.
- [How Long a Cold LinkedIn Request Takes to Become a Booked Meeting](https://www.reachium.io/research/cold-request-to-booked-meeting): Across 991 booked meetings that started as a cold LinkedIn connection request, the median time from sending the request to the booking was 5.83 days, 56.1% of bookings landed within a week of the send, and 85.1% within 30 days.
- [Do LinkedIn Follow-Ups Work? One in Seven Replies Says Yes](https://www.reachium.io/research/do-linkedin-follow-ups-work): Across 43,084 accepted LinkedIn connections with a recorded message step, 14.7% of all replies arrived after a follow-up message was sent, and among accepted prospects who stayed silent long enough to receive a follow-up, 13.9% then replied.
- [Do You Need a Big Network for LinkedIn Outreach?](https://www.reachium.io/research/does-network-size-matter-linkedin): Our analysis of 98,500 matured LinkedIn connection requests found accounts now holding 5,000 or more connections had 34.9% of their cold requests accepted against 23.2% for accounts in the 500 to 999 band, a gap that cannot be read as causal because successful sending is itself what grows a network.
- [Everyone Runs at the Cap: What a Real LinkedIn Sending Day Looks Like](https://www.reachium.io/research/everyone-runs-at-the-cap): Across 10,023 active account-days of LinkedIn outreach, 75.8% ran at 25 or more connection invites, and the median sending day and the 90th-percentile sending day are the same number: 25 invites, the platform ceiling.

We Checked 655,442](https://www.reachium.io/research/how-many-b2b-emails-are-valid): Of 655,442 B2B email addresses put through verification, 54.0% came back verified as deliverable, 18.1% resolved to catch-all domains, 14.6% bounced, 9.4% could not be determined, and 4.0% were pattern-generated guesses.
- [LinkedIn Acceptance by Company Size: Enterprises Say Yes More](https://www.reachium.io/research/linkedin-acceptance-by-company-size): Across 20,855 matured LinkedIn connection requests matched to a company size band, people at companies of 1 to 10 employees accepted 18.9% of cold requests while people at companies of 10,001 or more accepted 25.9%, a 7-point gap running opposite to the common assumption.
- [LinkedIn Acceptance by Industry: an 11-Point Spread](https://www.reachium.io/research/linkedin-acceptance-by-industry): Across 30,364 matured LinkedIn connection requests matched to a target industry, acceptance ranged from 19.8% in Energy to 30.9% in Business Services, an 11.1-point spread, six times the size of the day-of-week effect in the same dataset.
- [Your Acceptance Rate Dropped 5 Points. It Probably Means Nothing](https://www.reachium.io/research/linkedin-acceptance-rate-noise): Our analysis of 82 same-workspace consecutive-month pairs of LinkedIn outreach found the median month-over-month acceptance-rate swing was 5.69 points, 54.9% of month pairs swung 5 points or more, and 31.7% swung 10 points or more.

- [The B2B Company Universe Is Smaller Than Your TAM Slide](https://www.reachium.io/research/the-b2b-company-universe): Across 130,030 size-classified companies in a 933,544-company B2B database, 69.1% have 200 or fewer employees, 49.7% have 50 or fewer, and only 14.2% have more than 1,000; among located companies, 55.2% are in the United States.
- [The Repeat Commenters: 4.8% of People Left 40% of the Comments](https://www.reachium.io/research/the-repeat-commenter-concentration): Across 16,661 keyword comments on one team's lead-magnet LinkedIn posts, 70.2% of the 7,582 commenters commented exactly once, while the 4.8% who commented five or more times produced 40.4% of all comments, and the single heaviest commenter left 200.
- [What 'C-Suite' Means in a B2B Database (Less Than You Think)](https://www.reachium.io/research/what-c-suite-means-in-a-b2b-database): Of 912,770 seniority-classified contacts in a large B2B database, 54.1% are tagged C-Suite, 63.8% are tagged C-Suite or Founder, and even the database's own stricter decision-maker rule keeps only 49.1% of the C-Suite-tagged contacts.
- [What's Actually in a B2B Database: 2 Million Contacts Audited](https://www.reachium.io/research/whats-in-a-b2b-database-2026): Across 2,037,030 B2B contact records counted exactly after deduplication, 17.3% are flagged as decision-makers, 52.6% have an email address on file, 40.2% have a phone number, and 44.8% carry a seniority classification.
- [When People Actually Reply on LinkedIn](https://www.reachium.io/research/when-people-reply-on-linkedin): Across 18,718 first replies to LinkedIn cold outreach, 51.5% arrived between 09:00 and 18:00 UTC, Tuesday carried more replies than any other day, and the average weekend day carried 42% fewer replies than the average weekday.
- [From Comments to Booked Meetings: A LinkedIn Content Funnel Measured End to End](https://www.reachium.io/research/comments-to-booked-meetings): Across 14,752 keyword comments on one team's LinkedIn lead-magnet posts, connection invites sent to commenters were accepted at 56.29%, against a 27.11% cold benchmark on the same platform, a different-population comparison rather than a controlled test, and 32.05% of the 6,063 leads created went on to reply in a DM conversation.
- [Do LinkedIn Connection Notes Work?](https://www.reachium.io/research/do-connection-notes-work): Among people who accepted a LinkedIn connection request, 47.8% replied when the request carried a note against 25.5% when it did not, a gap that held in all three customer accounts large enough to compare against themselves; the effect of a note on acceptance was tested and proved inconclusive.
- [Lead-Magnet Posts vs Standard Posts on LinkedIn: 78.5 vs 1 Median Comments](https://www.reachium.io/research/lead-magnet-posts-vs-standard-posts): Across 211 LinkedIn posts from one team, lead-magnet posts earned a median of 78.5 comments against 1 for standard posts, and the direction held in all four accounts with enough posts of both kinds to compare within one author.
- [LinkedIn Content Benchmarks 2026: What 211 Real Posts Earned](https://www.reachium.io/research/linkedin-content-benchmarks-2026): Across 211 LinkedIn posts published by one team of about 10 accounts, the median matured post earned 1,778 impressions and 35.5 reactions, while the average matured post earned 5,516 impressions, 3.1 times the median, because a small number of outlier posts carry most of the reach.
- [LinkedIn Follower Growth: 10 Accounts, 60 Days of Consistent Posting](https://www.reachium.io/research/linkedin-follower-growth-60-days): Ten LinkedIn accounts posting consistently grew their combined followers from 18,428 to 26,075 in 60 days, a 41.50% increase, though 73.95% of that growth moved in step with connection growth from the same accounts' outreach, so posting alone cannot claim the full number.

- [LinkedIn Acceptance Held Steady While Reply Rates Fell](https://www.reachium.io/research/the-reply-rate-collapse): Between 2025 and 2026 LinkedIn connection acceptance rose slightly from 26.3% to 28.1%, while the share of accepted connections that produced a reply fell from 32.2% to 22.0%: getting connected became no harder, getting a conversation became considerably harder.

- [How Long a LinkedIn Connection Request Takes to Be Accepted](https://www.reachium.io/research/time-to-accept-time-to-reply): Across 53,142 accepted LinkedIn connection requests with a usable interval, the median time from send to acceptance was 25.4 hours, 46.7% were accepted within 24 hours and 92.0% within 30 days; among accepted connections that replied, the median time from acceptance to first reply was 31.0 hours.

## API & MCP

Programmatic access. 76 MCP tools and a 98-operation REST API over one surface: same keys, same scopes, same rate limits. Scopes are cumulative (launch ⊇ write ⊇ read); a read key exposes 33 tools that cannot send anything, and only 6 of the 76 can reach a person. Those are gated twice more: the first call to one returns a preview and a 5-minute token rather than executing, and every launch action has a hard daily cap. Every call writes an audit row. LinkedIn is reached through Unipile, a third-party session-based provider — Reachium is not a LinkedIn partner and uses no official LinkedIn API. Claude and generic MCP clients connect today; the ChatGPT connector is pilot-gated.
