Outreach is the moment a company turns data into a conversation: a first email, a call, a sequence of touches to a person who has not asked to hear from you. The outreach tool handles the sending, the scheduling and the reply tracking. Data infrastructure for outreach is everything the tool needs loaded before the first step fires: a verified email for a real person at an account that fits, the evidence of why now, and a first touch written from that evidence rather than from a template with a first-name merge field.
The term is having a moment because the sending side has been solved and the data side has become the bottleneck. Sequencers are excellent and interchangeable; mailbox providers have tightened sender rules; buyers have learned to recognize a template on sight. What separates a sequence that books meetings from one that burns a domain is now almost entirely what was true about each row before it was loaded. This guide is about that layer. The product page for the same job is Data Infrastructure for Outreach, and the outreach agent loads the drafts into the sequence tool your team sends from; the sending stays with your team and your tool.
What data infrastructure for outreach means
A sequence step is a small package: a recipient, a subject, a body, a send window. The recipient has to be a real person whose mailbox accepts mail. The body has to say something true about that person's company that a stranger could not have guessed. Infrastructure for outreach produces those packages at volume, so the rep's time goes to replies and calls rather than to research and copy-paste.
The pieces are familiar in isolation. Account selection, contact finding, email verification, research, drafting, loading. What the infrastructure adds is that the pieces run in order, per row, with the output of each carried into the next: the account's qualifying signal becomes the evidence in the draft; the verification status decides whether the row is loaded at all; the fit score decides its order in the batch. The outbound personalization with evidence guide covers the drafting half; this guide covers the whole stack.
The data jobs inside outreach
Identify. Pick the accounts worth a sequence this week and the two or three people at each who own the problem you solve. Selection is signal-led: an open role, a raise, a platform change, an intent surge. Enrich. Attach the evidence to the row. This is the step most teams skip, and it is the one that makes the first line specific: the title of the job posting, the size of the round, the technology that appeared or disappeared, the topic the account has been researching. Verify. Confirm the email is deliverable and the phone is live before the row reaches the sequencer, and confirm the person is still in the role. Score. Order the batch by fit and signal strength, and suppress customers, open opportunities, competitors and anyone contacted in the last ninety days. Deliver. Load the verified rows with their evidence and their drafted first touch into the sequence tool as a reviewable batch, deduplicated against what is already in flight.
The data layers behind a sequence that lands
| Layer | Fields that matter | Where they show up |
|---|---|---|
| Company data | Domain, industry, employee count, HQ, technologies in use, parent company, customer or competitor flag | Account selection, suppression, the "companies like yours" line |
| Person data | Name, title, seniority, department, tenure, location, work email, direct phone, time zone | Recipient, send window, the role-specific angle |
| Signals | Job posting title and date, funding round and date, technology adopted or dropped, news event, intent topic and recency, partnership | The first line, the reason for reaching out now |
| Verification | Email status (deliverable, catch-all, risky, invalid), phone status, verified date, role-still-current check, last-contacted date, suppression reason | Whether the row is loaded, and into which step |
| Delivery | Drafted first touch, sequence and step assignment, owner, CRM record ID, evidence source and date per line | The batch the rep reviews and the sequencer runs |
The role-still-current check earns a mention. A verified email for a person who left the company six weeks ago is technically deliverable and practically wasted, and it is common on lists more than a quarter old. Infrastructure that re-checks tenure at load time catches it. The email verification and deliverability guide covers the verification layer in depth.
Autonomous agents versus building the sequence data by hand
By hand, outreach data is a rep's morning: open the account, read the news, find the job posting, find the person, guess the email pattern, verify it if there is time, write the first line, paste into the sequencer, repeat. Ten minutes per account on a good day, and the tenth account gets less care than the first. An autonomous AI agent runs the same steps as a batch plan, with the evidence gathered from licensed sources, the contact verified before loading, and the draft written from the row's own fields.
| Step | By hand | Run by an autonomous agent |
|---|---|---|
| Account selection | Whatever is at the top of the list, or whoever emailed a lead | Accounts with a fresh signal and a fit score above the line, ranked |
| Research | Manual per account, inconsistent depth, undocumented | Evidence attached per row from hiring, funding, technology and news sources, with date |
| Contact and verification | Pattern guessing plus an occasional verifier run | Waterfall finder across licensed sources, every email verified, tenure re-checked |
| Suppression | Rep remembers, or does not | Customers, open opps, competitors and recent contacts removed automatically |
| Drafting | Template with a merge field, or a hand-written line for the top ten | First touch per row grounded in that row's evidence, in your voice and guardrails |
| Loading | CSV into the sequencer, duplicates in flight | Batch loaded into the sequence tool for review, deduplicated, parked for one approval |
The rep still decides what goes out. The batch arrives as a reviewable queue with the evidence visible on each draft, and the team sends from its own tool under its own rules. The agent's job ends at the loaded, verified, grounded row.
The same infrastructure serves the phone and the social touch. A call needs the direct or mobile number verified, the time zone from the person's location, and three lines of call notes drawn from the same evidence fields the email used. A connection request or a comment needs the profile URL and the one detail that makes it human. When all three channels read from one row with one set of evidence, the sequence tells a consistent story across a week, and the rep never has to reconstruct why the account was chosen when the reply finally comes in.
The metrics that show it is working
Four numbers, two from the mailbox and two from the pipeline. The figures are illustrative examples of a healthy mid-market outbound program.
97%verified-deliverable rate on loaded contacts (example)<1.5%hard bounce rate on the sequence, down from 6% unverified (example)8.2%reply rate on evidence-grounded first touches (example)2.4meetings per hundred contacts loaded (example)
Verified-deliverable rate and bounce rate are the pair that protects the sending domain; mailbox providers publish thresholds and a verified batch stays well under them. Reply rate is where the evidence layer shows up, and comparing grounded batches against template batches on the same accounts is the cleanest test of whether the research is earning its cost. Meetings per hundred contacts is the outcome, attributable to the signal that selected the account, so the program learns which signals produce conversations.
How AstroFabric does it
AstroFabric prepares outreach data as a mission and hands the finished batch to the tools your team sends from. Account selection runs on signals_feed, hiring_signals, funding_events, company_news and company_buying_intents, with company_lookup and tech_stack filling the account fields the draft will cite. People come from buying_committee and people_search, contact details from find_email and find_phone as waterfalls across licensed sources, and email_verify runs on every row before it can be loaded. buyer_intent_contacts surfaces the people at an account who are researching your category, which is the strongest opener there is.
outbound_draft writes the first touch, the sequence steps, the opener or the call notes from each row's evidence, inside the voice and guardrails you set. list_hygiene suppresses customers, open opportunities, competitors and recent contacts, list_score orders the batch, and list_push loads it into the connected outreach tool as a reviewable batch, parked for one approval; crm_upsert_contacts keeps the CRM in step. create_schedule prepares a fresh batch each week from the accounts that moved. Plans start at $49 per month, a verified contact is a few credits, and a finder call that finds nothing is free. The landing page for this job is Data Infrastructure for Outreach.
Frequently asked questions
What is data infrastructure for outreach?
The layer that prepares everything a sequence needs before the first step fires: accounts selected on a signal, the right people found, emails and phones verified, evidence attached per row, suppression applied, and a grounded first touch drafted and loaded into the sequence tool as a reviewable batch.
Does AstroFabric send the emails?
No. The agents prepare the data and the drafts and load them into the outreach tool your team already sends from, parked for approval. Sending, scheduling and reply handling stay with your tool and your team, under your rules, which keeps deliverability and consent decisions where they belong.
What makes a first touch grounded rather than templated?
It cites something that actually happened at the account and is stored on the row with a source and date: a job posting title, a funding round, a technology that appeared, an intent topic surging. The draft is written from those fields, so every row reads as researched because it was.
How does verification protect the sending domain?
Mailbox providers watch bounce and complaint rates per sending domain. Verifying every email before load keeps hard bounces well under the published thresholds, and re-checking that the person is still in the role removes the deliverable-but-wasted rows that old lists accumulate. Suppression removes the addresses that should never be contacted.
How much does outreach data cost?
Plans start at $49 per month and usage is credits. A verified contact is a few credits, a finder call that finds nothing is free, and enrichment is only charged when a licensed source answers. Drafting is metered per row, and credit ceilings enforced before spend keep a batch inside its budget.
