Notifications & Messaging That Reach Every Customer
Slack ops alerts, Twilio SMS, Resend transactional email, and Mailchimp campaigns, wired into your store as one reliable messaging layer.
Messaging that is scattered, unreliable, and blind
Most stores bolt on notifications one plugin at a time: an SMS app here, an email service there, a Slack webhook someone set up and forgot. The result is inconsistent. Order confirmations land in spam, OTP texts arrive late or not at all in some regions, and low-stock or failed-payment events surface hours after they mattered because nobody was alerted. Transactional messages get tangled with marketing sends, hurting deliverability and tripping consent rules. And when a customer says they never got their receipt, no one can see whether it was sent, delivered, or bounced. Across the USA, Europe, the Gulf, and the Nordics, that patchwork costs you trust, conversions, and hours of manual firefighting.
One notifications layer, four best-in-class channels
Hepek designs and builds a unified messaging layer for your commerce platform that routes every event to the right channel and audience. Internal operations alerts flow to Slack, so new orders, low stock, and failed payments reach the right team in real time. Customer-facing transactional SMS, OTP, and shipping updates go through Twilio, which delivers reliably across regions. Transactional email like receipts, order confirmations, and password resets is sent through Resend, a developer-first email API built for deliverability. Marketing email, campaigns, and lifecycle automation run on Mailchimp against segmented audiences. We keep transactional and marketing strictly separated, respect consent and unsubscribe rules, and instrument every send with delivery tracking so you always know what reached whom, in which language.
How it works
- 1
Map events to channels and audiences
We inventory every meaningful event in your store, from order placed and payment failed to stock threshold crossed and shipment dispatched, and decide which channel and audience each one belongs to. Internal alerts, customer transactional messages, and marketing sends are separated by design from day one.
- 2
Wire internal ops alerts to Slack
We connect operational events to Slack channels so your team sees new orders, low-stock warnings, failed payments, and refund requests the moment they happen. Alerts are formatted for fast action and routed to the right channel, so nothing important sits unnoticed in a dashboard.
- 3
Build transactional SMS and email
We implement customer-facing transactional messaging through Twilio for SMS and OTP and Resend for email. Order confirmations, receipts, password resets, OTP verification, and shipping updates are triggered by real events, templated cleanly, and localized for each market you serve.
- 4
Connect marketing campaigns via Mailchimp
We sync customer and order data into Mailchimp audiences so your marketing team can run campaigns, segment by behavior, and automate lifecycle flows like welcome series, abandoned-cart, and win-back, all with consent handling and clean separation from transactional traffic.
- 5
Instrument deliverability and monitoring
We add delivery, bounce, and open tracking with webhooks, plus fallbacks and retries, so failed sends are visible and recoverable. Domain authentication and sender reputation are configured up front to keep transactional messages out of spam.
- 6
Localize and roll out by region
We enable multilingual templates and region-aware routing so customers across the USA, Europe, the Gulf, and the Nordics receive messages in the right language and format, then launch each channel with monitoring in place.
Technology
Slack
Internal operations alerts. New orders, low-stock warnings, failed payments, and refund requests are pushed to the right Slack channels in real time, so your team acts on events instead of discovering them late in a report.
Twilio SMS
Customer-facing transactional and marketing SMS. Twilio powers OTP verification, order and shipping updates, and reminders with reliable delivery across the USA, Europe, the Gulf, and the Nordics, plus optional WhatsApp where it fits your audience.
Resend
Developer-first transactional email. Receipts, order confirmations, password resets, and account notifications are sent through Resend's email API, built for strong deliverability, clean templates, and real-time delivery webhooks.
Mailchimp
Marketing email and automation. Campaigns, newsletters, segmented audiences, and lifecycle flows like welcome, abandoned-cart, and win-back run in Mailchimp, kept fully separate from transactional traffic and respecting consent.
Benefits
Transactional and marketing kept separate
Receipts and OTP go through channels built for reliability, while campaigns run in Mailchimp. Separating the two protects deliverability, honors unsubscribe rules, and keeps critical messages out of the promotions folder.
Real-time visibility for your team
Slack alerts turn silent database events into action. Low stock, failed payments, and new orders reach the right people instantly, cutting the delay between something happening and someone handling it.
Messages that actually get delivered
Domain authentication, sender reputation setup, retries, and bounce tracking mean customers reliably receive their confirmations, OTPs, and shipping updates, so support tickets and lost trust drop.
Multilingual, region-aware messaging
Templates and routing adapt to each market, so customers across the USA, Europe, the Gulf, and the Nordics get notifications in their own language and format without extra manual work.
One layer instead of a plugin patchwork
A single notifications architecture replaces a stack of disconnected apps, so events, channels, and audiences are managed in one place and are far easier to extend or debug.
Full audit trail of every send
Delivery, bounce, and engagement events are tracked end to end, so when a customer asks about a message you can see exactly whether it was sent, delivered, or failed.
Frequently asked questions
What is the difference between transactional and marketing notifications?
Transactional messages are triggered by a specific user action or required for the account, such as order confirmations, receipts, password resets, OTP codes, and shipping updates. Customers cannot unsubscribe from them. Marketing messages, such as newsletters, promotions, and campaigns, are sent to an audience and require consent and an unsubscribe option. Hepek keeps the two on separate channels, using Twilio and Resend for transactional messages and Mailchimp for marketing, which protects deliverability and keeps you compliant.
Which channel handles internal alerts versus customer messages?
Slack handles internal operations alerts for your team, including new orders, low stock, and failed payments. Customer-facing messages go out over Twilio for SMS and OTP and Resend for transactional email, while Mailchimp handles customer marketing. Hepek maps each event to the correct channel and audience so internal and customer messaging never get mixed up.
Can Hepek send SMS and email in multiple languages and regions?
Yes. Hepek builds multilingual templates and region-aware routing so customers across the USA, Europe, the Gulf, and the Nordics receive notifications in the right language and format. Twilio and Resend deliver across these regions, and message content is localized per market rather than sent in a single default language.
How do you make sure transactional emails do not land in spam?
Deliverability is set up before launch. Hepek configures domain authentication such as SPF, DKIM, and DMARC, warms sender reputation, and sends transactional email through Resend, which is built for high deliverability. Keeping transactional traffic separate from marketing sends further protects inbox placement, and bounce and delivery webhooks flag any issues early.
Can I get a Slack alert when stock is low or a payment fails?
Yes. Hepek wires operational events straight to Slack, so low-stock thresholds, failed payments, new orders, and refund requests post to the right channel in real time. Alerts are formatted for fast action, so your team responds to problems as they happen instead of finding them later in a dashboard.
Do I have to replace my existing email or SMS provider?
Not necessarily. Hepek designs the notifications layer around the best fit for each job and can integrate Slack, Twilio, Resend, and Mailchimp alongside or in place of what you use today. We assess your current setup first and recommend the cleanest path. To discuss your stack, email info@amygdal.com.
