Unique Links
Give every lead an attributed link
Generate a personal URL for every row in your list, then use those links in the sequence tool or channel your team already runs. Engagement stays connected to the lead and company instead of disappearing into campaign totals.
- Generate links individually, from CSV, or through the API
- Keep contact and company attribution intact
- Use any sequence tool or channel that accepts a link

Account-based outreach
Use first-party engagement to support account-based outreach
Give each contact on a target-account list a personal link tied to the right company. When viewing activity returns or the same link records additional viewing sessions, SDRs, AEs, and marketing have a shared reason to coordinate the next touch.
- 01
- Additional viewing sessions on the same personal link can indicate that collateral is being reopened or circulating inside the account.
- 02
- Return visits and viewing time by page provide account context without requiring another third-party intent feed.
Account engagement map
4 viewing sessions detected on a single personal link
Return Visits
Use return visits to time the next touch
When a personal link records another visit days or weeks later, your team gets a fresh engagement signal and can review the pages viewed again.
- Real-time alerts for recorded return visits
- See which pages were viewed again
- Timestamps and engagement data for recent sessions

API for outbound automation
Create an attributed case study link for every lead with the API
Call HummingDeck from a script or agent workflow to create a personal tracked link for each row in your list. Merge the returned URLs into the sequence or channel you already use, then retrieve recent document views for your GTM workflow. REST API access is available by request on Business.

Open rates describe inbox activity, not engagement with your sales collateral
A click is only the handoff
A sequence tool can record the click, but it cannot show how long the case study remained in view or which pages recorded viewing time.
Campaign totals hide the lead
Aggregate opens and clicks do not tell an SDR which attributed link recorded a longer viewing session, a return visit, or activity from another session.
Pipeline timing needs context
Viewing time by page, return visits, and activity from additional viewing sessions provide more useful context for deciding when and how to follow up.
Bot Detection
Reduce noise from automated activity
HummingDeck uses user-agent analysis, IP geolocation, and client-side interaction signals to filter known and likely security scanners, link prefetchers, and crawlers.
- User-agent analysis catches known bots
- IP geolocation filters data center traffic
- Interaction signals help separate interactive sessions from prefetching

From engagement to pipeline
Use document engagement to determine the next GTM action
The same first-party activity can support different decisions across the revenue team without forcing everyone into another campaign dashboard.
SDRs
Prioritize attributed links with longer viewing sessions, return visits, or activity from additional viewing sessions.
AEs
Prepare calls with context about the use cases, proof, or pricing pages that recorded longer viewing time.
Growth
Compare completion and viewing time by content type across lists, segments, and campaign channels.
RevOps
Standardize attributed-link creation through CSV or API and route engagement into existing workflows.
ABM teams
Coordinate account touches when viewing activity returns or the same personal link records additional sessions.
For multi-document follow-up
When follow-up includes more than one deck, bring it into a branded Room
As a deal progresses, follow-up often expands to include a proposal, pricing, case studies, and next steps. A Room keeps the documents, mutual action plan, and buyer discussion behind one link that stays current.

Compare all featuresFrequently asked questions
How is this different from my cold email tool's tracking?
Cold email tools report inbox events such as pixel loads and link clicks. HummingDeck measures activity inside the collateral after the click, including viewing time by page, return visits, and additional viewing sessions, while filtering known and likely automated traffic.
What about click tracking in Smartlead / Instantly / Lemlist?
Those tools can report that a URL was clicked. HummingDeck shows recorded viewing activity inside the case study, one-pager, or deck after the handoff, so your team can use viewing time by page and return visits when planning follow-up.
Can I generate unique links for each prospect?
Yes. Upload a CSV of contacts and HummingDeck generates a unique tracked link for each one. Paste those links into your sequence tool. Every recipient gets their own link, and engagement is attributed individually rather than in aggregate.
What content should I share?
Anything your prospect would find genuinely valuable: a relevant case study, industry research, a competitive analysis, or a pricing one-pager. The content should be useful on its own. HummingDeck shows the recorded viewing activity.
Do prospects need to create an account?
No. They click the link and view immediately, with no login or app install. For sensitive documents, you can optionally require email verification.
Does this integrate with my CRM?
HummingDeck integrates with Close CRM and can send real-time notifications through email and Slack. The REST API is available by request on Business for creating attributed links and retrieving recent document views for your own GTM workflows.
