Email automation that runs without anyone remembering.
Manual email processes don't scale with your business. Transactional emails that require someone to send them, onboarding sequences that run inconsistently, follow-up emails that get forgotten, and reporting emails that take staff hours to assemble, all of these are automation problems. We build email automation systems that send the right email at the right time based on what happens in your product and your business, without anyone having to remember to do it.

Transactional emails sent manually or through processes that break when someone is sick?
Onboarding sequences inconsistent because they depend on a salesperson to execute them?
Short answer
RaftLabs builds email automation for businesses across the US, UK, Europe, Canada, and the UAE: transactional infrastructure, onboarding sequences, and reporting emails. We build deliverability-first: authentication and suppression before sequences. A transactional v1 ships in 4-6 weeks from $8,000; a full lifecycle system grows to 10-14 weeks. You own the source code.
Key takeaways
RaftLabs builds email automation systems covering transactional infrastructure, behavioural sequences, onboarding workflows, and automated reporting emails.
We build deliverability-first, authentication (SPF, DKIM, DMARC), warmup, and suppression before a single sequence, because a broken sender reputation makes every later feature worthless.
A transactional v1 ships in 4-6 weeks; a full onboarding and lifecycle system grows to 10-14 weeks, at a fixed cost with full source code ownership.
InvestIQ's event-triggered subscription alerts (push and email) reached 5,000+ active users in 90 days, built on AWS Lambda scheduled triggers and SNS delivery.
A transactional email system runs $8,000-$20,000; a full onboarding and lifecycle automation system runs $20,000-$50,000.
Below roughly 500,000 emails a month, staying on a hosted ESP is usually the cheaper option, above that volume the math starts favoring an owned transactional relay.
Integrations supported: SendGrid, Mailgun, Amazon SES, and custom email platforms, with SPF, DKIM, and DMARC configured for deliverability.
Trusted by
The order confirmation that never went out.
The order confirmation sent by a team member who is on leave. The onboarding email that depends on a sales rep to trigger it. The weekly report assembled in a spreadsheet by someone who is juggling other priorities. When the person responsible is unavailable, the email doesn't go out.
Email automation turns process reliability into a software problem. The trigger fires, the message sends, the record updates, and no one had to remember any of it.
Software doesn't take sick days.
According to McKinsey's November 2021 report, "The Value of Getting Personalization Right—or Wrong—Is Multiplying," companies with faster growth rates derive 40% more of their revenue from personalization than their slower-growing counterparts. Behavioural email automation is one of the highest-leverage places to apply that principle: the message goes out the moment a user's action calls for it, not on the next scheduled batch.
Password resets are a specific, common failure case worth naming directly. Send them through a marketing platform instead of a dedicated transactional stream, and they can land under a promotions tab a user never opens, or get throttled behind a marketing send with a bad reputation. It's the kind of failure that doesn't show up in a demo. It shows up in a support queue instead.
We have shipped production software since 2015 for clients that include Vodafone, T-Mobile, Aldi, Cisco, and Lockheed Martin, with a 4.9/5 client rating on Clutch. That work spans healthcare, fintech, logistics, and hospitality. The team that scopes your email infrastructure is the team that ships it: the engineers you meet in week 1 are the ones live at launch, no offshore handoff after the contract is signed.
Email automation pays off when the sending is reliability-critical, not a one-off broadcast.
Everything on the left should already be true for your operation. Even one thing on the right, and a marketing tool or a manual process is the smarter first step for now.
A fit
01
You send transactional, onboarding, or lifecycle emails that today depend on someone remembering to trigger them.
02
You have product, billing, or CRM events (sign-ups, payments, milestones) that should drive email automatically, plus systems like SendGrid, Stripe, or HubSpot to integrate against.
03
You want to own the code and run sequences as version-controlled configuration, not locked inside a drag-and-drop builder.
Not a fit
You need a simple newsletter or one-off broadcast that a marketing tool like Mailchimp already covers.
Your email volume is low enough that manual sending is not yet a reliability problem.
You want a marketer to manage campaigns, not a system wired to your product events.
What we build
What we automate
01
Transactional email infrastructure
Reliable transactional email infrastructure for every system-triggered message your product sends: password resets, order confirmations, payment receipts, and account changes. Authentication is configured before the first send, with a dedicated transactional subdomain so marketing traffic never hurts delivery, and bounces and complaints feed suppression lists automatically. Built on SendGrid, Mailgun, Amazon SES, or Postmark with SPF, DKIM, and DMARC in place from day one.
02
Onboarding and activation sequences
Onboarding email sequences triggered by sign-up events and in-product milestones, not by a salesperson remembering to send them. The welcome email fires within 60 seconds of account creation via a webhook against Auth0 or Firebase, milestone emails acknowledge progress, and personalisation data is pulled at send time so every email reflects the user's current name, plan, and use case.
03
Behavioural trigger emails
Emails triggered by product events or data conditions, not calendar dates, using your product's event stream as the trigger source. We build feature limit warnings, dormant user re-engagement, upsell signals, and checkout abandonment, with frequency capping across all triggers and a conversion check before each send so nobody gets nudged about something they already did.
Subscription lifecycle email automation covering renewals, payment failures, and churn recovery, the highest-revenue-impact automations for any subscription business. Renewal reminders run off the actual subscription record, dunning sequences fire on failed-payment webhooks aligned to your billing platform's retry schedule and exit on successful payment, and win-back sequences start three days after cancellation. Wired to Stripe, Chargebee, or Recurly.
Most shops build the sequences first and treat deliverability as a launch-week checklist. We run it in reverse, and the order is the whole opinion. A behavioural sequence that lands in spam is worse than no sequence, because it burns sender reputation you then have to rebuild. So we earn the inbox before we automate anything into it. Six stages, always run in this order, never skipped.
Our method
The deliverability-first build order
Authentication and hygiene come before a single sequence, because a broken sender reputation makes every later feature worthless.
01
Authenticate the sender
SPF, DKIM, and DMARC records configured and monitored first, with BIMI where the brand qualifies. Without these three, mailbox providers have no reason to trust the sending domain, and no later feature makes up for it.
02
Separate and warm the streams
Transactional and marketing email get different subdomains and sending identities, so a marketing blast can never tank password-reset deliverability. New domains and IPs are warmed gradually, not opened at full volume on day one.
03
Hygiene and suppression before the first send
Bounce and complaint handling, automatic suppression of hard bounces and unsubscribes, and list validation are wired in before any production traffic. A dirty list poisons reputation faster than any content problem does.
04
Segment by behaviour, not by list
Sends are keyed to what a user did or did not do in the product, not to a static list membership. Frequency capping runs across every trigger, so no one is over-sent whatever combination of events they hit.
05
Automate the lifecycle triggers
Only now do the sequences go in. Webhook receivers with signature validation, idempotency controls, and a retry queue with a dead-letter path feed version-controlled sequence logic. Personalisation is resolved at send time, with fallbacks so no merge tag ever ships visible.
06
Optimise on real deliverability data
Delivered, opened, clicked, bounced, and complained events captured in real time and correlated with business outcomes. Step-level drop-off funnels, bounce and complaint dashboards, and A/B winners declared only at statistical significance.
ESP-native automation vs a custom automation layer
The real decision is not "which ESP." It is how much of the trigger and reliability logic you own versus rent from a drag-and-drop builder. Here is the honest split.
Transactional, onboarding, and lifecycle sends where a missed email is a real problem
Email automation that runs without anyone having to remember
Transactional infrastructure, behavioural sequences, and reporting emails that run on your data and your triggers. We build and configure, you own the code.
How it works
From scope to shipped
Every project follows the same four phases. Scope is locked and price is fixed before development starts.
Week 1
01
Audit and scope
We map every email your business currently sends manually or inconsistently, identify the trigger sources, and spec the sequences to build. You leave week 1 with a written scope document and a fixed-price quote. No development starts without your sign-off.
Weeks 2-3
02
Infrastructure and design
DNS configuration, sending domain setup, and ESP integration before a single sequence is built. Template designs reviewed and approved before production code. Decisions made here cost ten times less than changes made in week 8.
Weeks 4-10
03
Build, integrate, and QA
Sequences built in priority order with staging delivery confirmed before each goes live. Trigger integrations tested against your actual product events. QA runs in parallel with every sprint, not as a phase at the end.
Weeks 10+
04
Launch and post-launch support
Production deployment with delivery monitoring and alerting active on launch day. 8 weeks of post-launch support included in every project. Deliverability metrics tracked and reported weekly.
Pitfalls we plan around
Most email-automation projects fail in the same three places. Naming them up front is how we design them out, not a disclaimer we add after launch.
Deliverability collapse and spam traps
A cold domain, a purchased or stale list, or a shared IP with a bad neighbour can put you in the spam folder on day one, and a spam-trap hit can blacklist the domain outright. We warm domains gradually, validate lists before import, keep transactional off the marketing IP, and monitor DMARC reports and complaint rates so a reputation slide is caught early, not after the inbox placement is already gone.
Over-sending and notification fatigue
Independent sequences that each look reasonable can stack into five emails a day for one user who hit several triggers at once. That trains people to unsubscribe or mark spam, which then hurts everyone's deliverability. We enforce global frequency caps and a per-user send ledger across every sequence, plus a conversion check so nobody is nudged about something they already did.
Broken and duplicate triggers
A webhook that retries, an event that fires twice, or a queue that drops under load means a customer gets two receipts or none. We validate every webhook signature, key sends with idempotency controls, and run a retry queue with a dead-letter path so a spike or an upstream retry never turns into a wrong or missing email.
Do you have a dedicated email-automation case study?
InvestIQ above is our closest real, verifiable proof, an event-triggered, deadline-aware alert system delivered by push and email. It's a market-data product, not a pure transactional-email build, and we say so directly rather than dress it up as something it wasn't.
What if we're locked into an ESP's own internal security posture?
It's a fair worry. Mailchimp reportedly disclosed internal-tool compromises exposing customer mailing-list data in both March 2022 and January 2024, and Epsilon, one of the largest email-marketing vendors at the time, was reportedly breached in 2011, exposing data tied to 50+ client brands. Your ESP's access controls become part of your own security posture the moment you send through them. What we control on our side: you own the trigger logic and the code, not just a configuration inside someone else's platform, so switching ESPs later is a config change, not a rebuild.
Do you write to marketing platforms too, or only transactional?
Both, but never on the same sending domain or IP. Marketing sends through Mailchimp, ActiveCampaign, HubSpot, or Klaviyo; transactional and lifecycle sends go through a dedicated stream. That separation is configured before the first production send, not added after a marketing blast tanks your password-reset deliverability.
What email automation development costs
We scope every project before pricing it, so you know the number before development starts. Where you land depends on the number of sequences, the complexity of the trigger logic, and the data integrations required.
Transactional email system, $8,000-$20,000
Password reset, order confirmation, and account notification emails with delivery monitoring. Typically 4 to 6 weeks from scoping to production.
Onboarding and lifecycle automation, $20,000-$50,000
A complete system with 5 to 10 sequences, product event integration, and an analytics layer. Typically 10 to 14 weeks.
What it costs
Email automation, starting at $8,000.
Transactional infrastructure, behavioural sequences, and reporting emails that run on your data and your triggers, with full source code ownership at handover.
Starts at $8,000
Transactional systems ship in 4 to 6 weeks. Most clients start there, then add behavioural sequences and multi-channel notifications once the first system is live.
Start with transactional email, prove the infrastructure works, then expand into behavioural sequences and multi-channel automation as the case for it builds.
No hourly billing
Once we scope your first system, that price is locked in writing. No hourly billing, no surprise invoices. A scope change is a priced change request, agreed before work begins.
ROI scoped first
We calculate the hours saved, error-rate reduction, and revenue impact of each automation sequence before you sign off. You know the return before the build starts, and you own the source code at handover.
Email automation is software that sends emails automatically based on triggers, user actions, time delays, data conditions, or external events. Types we build: (1) Transactional emails, password resets, order confirmations, payment receipts, account changes. (2) Onboarding sequences, welcome emails, feature introduction, activation nudges triggered by sign-up and product actions. (3) Behavioural emails, triggered by specific user actions or inactions in your product. (4) Follow-up sequences, sales follow-up, churned user win-back, subscription renewal reminders. (5) Reporting emails, automated digests, performance reports, and alerts assembled from your data and sent on schedule.
We integrate with all major transactional email platforms, SendGrid, Mailgun, Amazon SES, Postmark, and Resend. For marketing email sequences, we integrate with or build alongside Mailchimp, ActiveCampaign, HubSpot, Klaviyo, and Customer.io. The right platform depends on your email volume, use case mix, and existing tools. We help you choose or work with what you already have.
Deliverability is a system design consideration, not an afterthought. We configure SPF, DKIM, and DMARC DNS records, implement bounce and complaint handling to maintain sender reputation, separate transactional and marketing email streams (different sending IPs and domains), implement list hygiene with automatic suppression of bounced and unsubscribed addresses, and monitor deliverability metrics. Poor deliverability typically comes from poor infrastructure setup and list management, not from content.
A transactional email system, password reset, order confirmation, and account notification emails with delivery monitoring, typically runs $8,000-$20,000. A complete onboarding and lifecycle email automation system with 5-10 sequences, product event integration, and analytics runs $20,000-$50,000. Multi-channel systems with email, SMS, and in-app notifications run higher. Cost depends on the number of sequences, the complexity of the trigger logic, and the data integrations required. We scope every project before pricing it.
A focused transactional email system takes 4-6 weeks from scoping to production. A full lifecycle automation system with 5-8 sequences, trigger integration, and an analytics layer typically takes 10-14 weeks. Timeline depends on the number of sequences, the complexity of trigger logic, and how many third-party integrations are involved. We scope the project in week 1 and give you a fixed timeline before any development starts.
Yes. We sign mutual NDAs before any project discussions involving proprietary business logic, customer data, or system architecture. We have signed NDAs for clients in healthcare, fintech, and SaaS across the US, UK, and Canada. Reach out and we will send the NDA before the first call if that is your preference.
Below roughly 500,000 emails a month, staying on a hosted ESP is usually the right call, we'll say so directly rather than talk you into a build you don't need. What a hosted ESP doesn't sell you is the trigger reliability layer: the webhook receivers, signature validation, idempotency controls, and retry queue that decide whether an event actually fires the right email, and it doesn't stop your transactional and marketing streams from sharing sender reputation unless you configure that separation yourself. That configuration and trigger layer is what we build, on top of whichever ESP you're already using. If you're at the volume where the ESP bill itself is the problem, that's a different, bigger conversation, see our transactional email system cost breakdown for when replacing the ESP outright starts to pay for itself.
No, and the distinction matters. The pricing on this page assumes you keep using a hosted ESP (SendGrid, Mailgun, SES) and we build the sequences, trigger logic, and integration on top of it. The $40,000-$120,000 range in our transactional email cost breakdown is for replacing the ESP relay itself with owned infrastructure, a different, larger scope that only makes sense at high volume (roughly 500,000+ emails a month, per that post's own break-even math). Most clients on this page need the former. We'll tell you plainly if your volume means you should be looking at the latter instead.
