A customer who never heard it shipped
They found out from a changelog.
BoldBellowsLinear to email automation for product teams that track customer requests
Linear to email automation that tells each customer who asked for a fix or feature when the issue ships, once, from an approved template, with no internal detail
Linear to email automation turns customer requests into a closed loop. Linear can link an issue to the customers who asked for it, reports a state change with the previous state attached, and signs the delivery with a timestamp that must be fresh to within 60 seconds. BoldBellows logs which Linear event this is, which issue it concerns and when it happened, holds the update until the issue's state and team have been confirmed, then finds each linked customer, writes one message from an approved template when the issue reaches a shipped state, and records which customer was told about which issue.

Chapter 01 the unclosed-loop problem
A feature shipped quietly loses the customer who asked for it
A customer asks for a feature in a support thread, the request becomes a Linear issue, and months later it ships. The customer finds out from a changelog they never read. A hand-written follow-up is sent when someone remembers. Automate it loosely and every state change emails the customer, an issue reopened and closed again emails them twice, and a message includes the engineering team's private notes.
We shipped the fix and the customer who reported it found out from the release notes.
An email for every state change
Internal movement reached the customer.
The same notice, twice
A reopened issue notified them again.
Before
After
Before
- Every event is written as it arrives
- Follow-ups depend on someone remembering
- Internal notes can leak into emails
After
- Each write is keyed on the Linear issue UUID and the customer ID, recorded for every message sent
- Each customer is told once when it ships
- Messages use approved wording only
Chapter 02 How it works
How a shipped Linear issue becomes one notice for each customer who asked
A change is admitted, identified, matched and written, always in that order.
Receive and qualify
The notification is authenticated, stamped with account, resource and time, then checked against the admission rule.
Verify, find, claim
The signature and timestamp are checked, the customers linked to the issue are found, and each issue and customer pair is claimed.
Build, send, record
Each notice is built from the versioned template and sent from an authenticated domain, and the version is recorded against the pair.
Linear and Email facts the design relies on
- Deliveries are signed: Every request carries a Linear-Signature header, an HMAC-SHA256 of the raw body made with the webhook secret, plus a delivery UUID, a timestamp and the event name.
- Timestamps stop replays: Linear asks receivers to refuse a delivery with a stale timestamp, so a captured request cannot be replayed to email customers a second time.
- If a reply is lost: The route reads Email through the Linear issue UUID and the customer ID, recorded for every message sent to learn whether the write landed, then acts on the answer.
Chapter 03 What ships in the build
Inside the route: what the Linear Email build holds
Foundation sets the rules and the key. Operations does the writing. Assurance compares both sides over time.
Admission rule engine
Decides which Linear events may proceed and logs why the others were set aside.
Stable identity ledger
Preserves the module, ID and time of each Linear change against the Email reference it created.
Allowlist mapper
Maps approved Linear fields to Email fields one by one and rejects anything not on the list.
Notice composer
Writes the email from the approved template with the customer's request, what shipped and where to see it.
Pair claim guard
Records each issue and customer pair before sending, so a reopened issue cannot notify twice.
Customer and rules matrix
Finds the customers linked to an issue and decides whether this state deserves a message.
Send register
Lines up Linear and Email on a schedule and lists what no longer agrees.
Domain health watch
Notices a failing SPF, DKIM or DMARC record before mail starts to bounce, for this Linear to Email route.
Owner queue
Gives each unresolved Linear case a named owner, so nothing waits in a shared inbox.
From linear to email historical migration to linear to email duplicate prevention and linear to email consultant, one route. Related searches include auto email from linear cycles, linear email automation, linear auto reply email, email customers from linear, linear to email error handling, linear to email service, linear to email implementation, notify requesters when linear issue ships, linear webhook email, linear to email Zapier, linear issues email notification, linear projects email trigger, linear to email, linear confirmation email, linear email notification, linear notification email, linear to email without Zapier, linear shipped issue customer email, linear customer requests email, linear custom email response and linear email alert setup.
Chapter 04 Who this fits
Built for product teams triaging customer feedback in Linear, and for anyone who must tell the customers who asked for a fix or feature that it has shipped
Linear knows what shipped and who asked; email is how that person is told.
Product manager
"Close the loop with customers."
Each customer who asked is told once when the issue ships.
Customer
"Tell me when you ship my request."
One email says what you asked for, what shipped and where to find it.
Support lead
"Don't expose internal notes."
Only approved wording and the fields you choose are used.
IT admin
"Mail must be authenticated."
Messages go out from a domain with SPF, DKIM and DMARC records in place, on the Linear to Email route.
Agency owner
"Customers must see only their own requests."
Recipients are scoped per workspace, so nothing crosses clients.
Founder
"Customers who feel heard stay."
People hear back without anyone writing to them.
Chapter 05 The options
Three ways to connect Linear and Email: release notes nobody reads, a zap, or a shipped-for-you notice route
Each can send mail. Only one tells each customer once and keeps the notes private.
| Question | release notes nobody reads | A standard Linear-Email connector | The BoldBellows shipped-for-you notice route |
|---|---|---|---|
| What starts the work | A person spots the update | Every matching hook runs | Only an issue event that meets the written rule |
| How identity is decided | Whoever it is checks the name | Email or name, compared as typed | A Linear issue UUID and customer ID for every message |
| What reaches Email | Fields typed from memory | Every mapped field, as plain text | One approved notice per customer when the issue ships |
| After an uncertain result | Someone checks by eye | Retry, or give up | Searches by the Linear issue UUID and the customer ID, recorded for every message sent, compares, then repairs |
A late notice follows a newer update
The timestamp on the incoming Linear event is checked first; a stale one is recorded and closed instead of rolling the email back.
An issue ships, is reopened, and ships again
The pair is already recorded, so no second email is sent; the reopening is logged and a follow-up goes out only if you have chosen to tell customers about a second fix. The route looks for the email through the Linear issue UUID and the customer ID, recorded for every message sent, compares it with the intended values and records a verdict: absent, correct, different or unclear.
Start the Linear to Email build with the Linear issue UUID and the customer ID, recorded for every message sent; the rest of the route leans on it.

Chapter 06 The process
Six steps to shipped-for-you notices customers value
From the first brief to the first month live, six steps with clear outputs.
-
About 30 minutes
Choose the shipped states
We agree which states count as shipped, how customers are linked to issues and whether any states need a delay before sending.
-
Access review
Approve access
For Linear to Email, we connect the two systems carefully, keeping access to what the agreed route requires.
-
Most of the project
Agree wording and recipients
Template wording, customer matching, the delay window and the sending domain are written down and signed off.
-
Before you review
Break it on purpose
For Linear to Email, we replay events, delay them, remove fields and revoke access in a safe Email copy before anything goes live.
-
Handover day
Launch with notes
The route is enabled from a fixed point in time and the PDF records every setting we chose.
-
About 30 minutes
Review after launch
Once real events flow, the opening weeks are checked against the evidence log so early surprises are caught and recorded.
Chapter 07 Turnaround
When each package goes live
Estimates run from approved access to handover, on the Linear to Email route.
Foundation
4 to 7 business days
Operations
7 to 11 business days
Assurance
11 to 17 business days
Chapter 08 Getting started
Your part in the first week
Scoped Linear access, approved by whoever administers it
A sending domain or mail service we can authenticate, and a Linear workspace admin to register the webhook
An authorised Linear connection for the resources named in scope
Your definition of which issue events should reach Email
Permission to run tests against a copy of Email
Your expected volume, so limits and pacing can be set
Chapter 09 Trust
Nothing is installed in Linear or Email, only mapped data moves
On this Linear to Email route, we ask for the smallest access that makes the route work and record exactly what that is.
Nothing installed inside either tool
The route talks to Linear and Email only through documented endpoints, so neither needs a plugin, a patch or a hidden setting.
Scoped, revocable access
Keys stay in your accounts, and their scope is listed for your auditors.
Only what the map allows
A written field map decides what crosses. Anything not on it, including private notes and billing data, is left behind.
Search before you write again
After any uncertain result the route looks for the email using the Linear issue UUID and the customer ID, recorded for every message sent; only a proven absence allows a new one.
Minimal logging
You can inspect exactly what is logged, and it contains no customer text.
Full handover
Your administrators receive a document they can follow without a briefing.
"A fix is worth announcing only to the people who asked for it, so the build finds the reporters before it writes a word."

Chapter 10 In their words
What BoldBellows clients say
Verified reviews from business owners who use BoldBellows automations every day, from marketing and data to support and operations.
AI Workflow Automation for Agencies

AI Accounting & Invoice Automation
BoldBellows automated our whole invoicing process: creating invoices, sending reminders and tracking payments.
Late payments dropped sharply, and our accounting team finally has time for strategy instead of repetitive admin. Worth every penny.
AI Data Entry & Reporting Automation
We used to spend hours collecting data and building weekly reports by hand. BoldBellows automated all of it.
The reports are clean, visual and easy to read, and our managers rely on them for quick decisions. Human error is gone and our numbers are more accurate across the board.
AI E-commerce Listings Automation
BoldBellows automated our product listings. The AI writes descriptions, organizes photos and publishes listings across several marketplaces.
It even answers customer questions instantly. Our store looks more professional and sales have noticeably increased.
AI Customer Journey Automation
We wanted a smoother path from first contact to purchase. BoldBellows built an AI system that guides each customer there automatically.
It sends personalized messages, recommends products and follows up at just the right moment. Customer retention has improved dramatically.
AI Document & Contract Automation
Onboarding was slow because we wrote every contract by hand. BoldBellows automated the lot: contracts, welcome emails and client setup.
What took 48 hours now takes under 10 minutes, and clients regularly tell us how professional it feels.
AI Social Comment & DM Automation
We get thousands of comments and messages every week. BoldBellows built an AI system that replies instantly, filters spam and surfaces the important ones.
Engagement is up and our page looks active around the clock. It’s like having a full social media team that never stops.

Our CRM was barely used because updating it by hand was tedious. BoldBellows automated data entry, tagging, segmentation and follow-ups.
Now the CRM is always up to date and our campaigns are far more accurate. It improved our whole sales pipeline.
AI Chatbot & Customer Support
BoldBellows built an AI support chatbot for our online boutique, and it has changed how we run the business. We used to have two full-time staff answering the same questions all day. Now the AI handles order tracking, product recommendations and even refund requests on its own.
What surprised me most is how natural it sounds. Customers compliment the ‘agent’ without realizing it’s AI. Our support workload dropped by 75% and customer satisfaction went up dramatically.
AI Content & Social Media Automation
Our marketing agency couldn’t keep up with content. BoldBellows set up an AI content engine that writes blog posts and captions and even designs our social media creatives.
It spots trends and suggests topics for us, so we stay ahead of competitors. We now produce three times the content with the same team, and engagement has soared. They didn’t just automate our workflow, they lifted our whole brand.
AI Lead Qualification & Sales Automation
Our sales team wasted hours chasing cold leads. BoldBellows built an AI lead-scoring system that reads behavior, email engagement and buying signals.
It filters out weak leads and sends personalized follow-ups automatically, so our team only talks to people who are ready to buy. Conversions rose 40% in the first month. It paid for itself straight away.
AI Video & Voice Automation
We publish product videos every week, and BoldBellows introduced us to AI video automation. The system writes the script, voices it and produces the finished video in minutes.
The quality is remarkable: professional voiceovers, clean visuals and smooth editing. Production time went from three days to under 30 minutes, and we scaled our video marketing without adding cost.
AI Booking & Scheduling Automation
Our coaching business needed a better way to schedule. BoldBellows automated all of it: bookings, reminders, cancellations and follow-ups.
No-shows fell by 60% and clients enjoy how smooth it is. It feels personal, not robotic. One of the best upgrades we’ve made.
AI Translation & Localisation
When we expanded abroad we needed fast, accurate translations. BoldBellows built an AI translation system that turns our content into several languages instantly.
The translations read naturally and suit each culture. We now serve customers in five new countries without hiring translators. BoldBellows helped us go global.

Our HR team was drowning in applications. BoldBellows automated screening, skills-based filtering and interview scheduling.
It saves us hours every week and means we only interview qualified people. Hiring is now faster, better organized and more professional.

Every automation they’ve delivered, from customer service to content, runs flawlessly. We’ve saved time, cut costs and grown faster than we expected.
Chapter 11 Questions
Linear and email: questions from product and support teams
Quick answers, no sales language, and a route to ask more.
Is a Linear to Email Zapier zap enough?
When an email for every state change is all that is wanted, a connector can manage that. It cannot find the customers who asked, write to each once when the issue ships and keep internal detail out. Those gaps are the reason this build exists.
How do I email customers when a Linear issue ships?
Issues linked to customers send one approved notice to each when they reach a shipped state, naming what they asked for and where to find it.
How are the customers found?
The route reads the customers linked to the issue and matches each to a stored contact. Anyone it cannot match is flagged, not guessed.
What if the issue is reopened?
Each issue and customer pair is recorded, so a second completion does not email the same person again unless you choose to.
Will internal comments appear?
Never. Messages use only the approved template and the fields you list, so descriptions and comments stay in Linear.
How is the delivery trusted?
Linear signs each request, and the route discards any whose timestamp is over a minute out.
Can a customer reply alter an issue?
No. The route sends and never listens, so no reply can edit anything in Linear.
Do I approve the Linear mapping before you build?
Yes, in writing. The Linear Email field mapping service yields a reviewed table of fields, formats and rules that you approve before launch.
Can you automate Linear data to Email as a custom workflow?
Yes. Conditions such as region, product or threshold become a custom Linear workflow for Email. We advise as a Linear Email integration consultant would, from $415.
What if Email changes its rules?
Work after the review window is scoped afresh.
Give your customers news about what they asked for
