Email and SMS for ecommerce brands
Email Marketing Agency for Ecommerce Brands
Enflow Digital is an email and SMS marketing agency for ecommerce brands on Klaviyo, Omnisend and Brevo: founded in 2022, Omnisend Strategic Partner, working with stores in the US, UK and Europe. If flows are missing or switched off, or your list no longer opens, we fix that first. It starts with a free audit.

Trusted by 100+ brands
Why ecommerce brands choose Enflow Digital
A founder-led agency, strategy built on your data, an honest platform comparison and a small senior team.
Founder-led
Both founders run Enflow day to day. They built ecommerce businesses before this, with exits, and have worked in email since 2018.
Revenue-first, data-led
Every plan starts with an audit of your account data, checked against what worked for other stores. You get a ranked list of fixes, and we build in that order.
Multi-platform
We run Klaviyo, Omnisend and Brevo, and work in ActiveCampaign, Mailchimp and MailerLite. We recommend the one that fits your stack and growth plan.
Senior specialists
A team of 10, each with 3 to 20 years of experience, and a named project manager who runs your account day to day.

Email, SMS and retention marketing services for ecommerce brands
An email marketing agency plans, writes, designs and sends a store's emails, builds the flows that send on their own, and keeps the list healthy. We do all of that, plus SMS, WhatsApp and direct mail.
Campaigns and email management
Planned sends instead of last-minute campaigns: we handle strategy, copy, design, sending and revenue reporting by campaign.
Email flows
We build and fix your email flows: welcome, abandoned cart, post-purchase and win-back, including flows that stopped working.
SMS marketing
SMS added to your flows and campaigns, with consent and compliance handled from the first message.
WhatsApp marketing
WhatsApp as a third channel next to email and SMS, with consent rules built in.
Direct mail automation
Physical letters and postcards triggered by customer behavior, such as a lapsed high-value buyer.
Signup forms, apps and integrations
We build pop-ups for list growth and connect your loyalty, review and subscription apps and identity resolution tools.
List health and deliverability
We fix what sends you to spam: SPF, DKIM, DMARC, sender reputation and list hygiene.
Free audit and strategy
A free review of your flows, list, segments and sending setup, with written fixes ranked by revenue potential.
Platform selection and migration
We compare platforms against your stack and growth plan, then migrate lists, flows and templates and test before cutover.
Most brands that hire us want retention marketing and lifecycle marketing: the emails, texts and letters that bring customers back to buy again.
Partnered with Omnisend, Klaviyo and Shopify
Enflow Digital is an Omnisend Strategic Partner, a Klaviyo Partner and a Shopify Partner. Omnisend's story about our work calls us "one of the top 5 agencies worldwide out of more than 4,000 in the program".
Klaviyo, Omnisend, Brevo and more
We run the email platform that fits your stack, connected to your store and your retention tools.
Klaviyo
Deep segmentation and flows for data-led Shopify brands.
Omnisend
Email, SMS and push in one account, plus our free Magento 2 module.
Brevo
Email, SMS and WhatsApp in one account, priced by send volume.
Shopify, WooCommerce and PrestaShop
We work with stores on all three. Klaviyo, Omnisend and Brevo each connect to them with their own apps, so orders, carts and product views reach your flows.
Magento 2
Magento 2 stores on Omnisend connect through our free module, which syncs customers, orders, products and store events.
Retention tools
We connect loyalty, list growth and direct mail tools to your flows, such as Smile.io, Retention.com and PostGrid.
We also work in ActiveCampaign, Mailchimp, MailerLite and others.
How we decide what to build first
We start with an analysis of your data and build what is likely to earn the most first.
We begin with the welcome flow, the abandonment flows (cart, checkout, browse) and the win-back flow. Then we expand into post-purchase, loyalty, sunset and other flows. You pay first for the work with the highest revenue potential, so your budget goes further.
Welcome
Every new subscriber sees the welcome flow.
Abandonment (cart, checkout, browse)
Abandonment flows reach shoppers who already showed intent.
Win-back
The win-back flow reaches past buyers who went quiet.
Then post-purchase, loyalty and sunset
We add these flows once the first three run well.
How it works
We work in four steps, from a free audit of your account data to reports on revenue by flow and campaign.
Discovery
We audit your account data, goals, budget, list health and current setup for free.
Strategy
We rank opportunities by revenue potential and agree a plan that fits your budget.
Implementation
We build and launch flows and campaigns in your platform, highest earners first.
Measurement and reporting
We report revenue from email by flow and campaign, test changes and show what moved.
What we need from you: access to your email platform and store analytics, your brand files, and a yes or no on each draft. Your project manager runs the rest.
What to check before you choose an email marketing agency
Ask these six things on the first call: platform experience, results you can verify, who does the work, deliverability and consent, reporting and access, and contract terms. Here is our answer to each.
Platform experience
Ask which platforms the team works in for clients today. We work in Klaviyo and Omnisend every day and also run Brevo, ActiveCampaign, Mailchimp and MailerLite.
Results you can verify
Ask for results that someone other than the agency has published. Omnisend has published two customer stories about our work, and our reviews sit on the Omnisend partner directory and Clutch.
Who does the work
Ask who will plan, write and design your emails. Every account at Enflow Digital has a named project manager, a copywriter and a designer. You approve the drafts and we do the rest.
Deliverability and consent
Ask how the agency protects your sender reputation and consent records. We set up SPF, DKIM and DMARC, the records that prove an email comes from you, before sending volume rises. SMS and WhatsApp run with consent recorded.
Reporting and access
Ask who owns the account and how results are measured. The account and designs stay yours, with full access. We report revenue by flow and by campaign, and show how each figure was measured, not only the platform's attribution.
Contract terms
Ask how long the contract runs before you sign anything. There is no long-term contract with Enflow Digital: the work runs month to month, and you can stop with notice.
Experience across ecommerce niches
We run email and SMS only for ecommerce brands, across skincare and beauty, health and wellness, pet care, outdoor and sports, apparel and accessories, and food and drink.
What our clients say
Founders and marketing leads of ecommerce brands describe their work with Enflow Digital.

Suhail Rivera
Founder of Alkaline Herb Shop
Enflow Digital is the best company I have ever worked with. They are professional and on top of everything. They also create the most beautiful emails and have a lot of experience doing the work they do. I love that they do the research to help me come up with the best campaigns and that they have taken the time to learn our store. The emails they craft are usually filled with upsells, and the visuals are unparalleled.

Renee Moore
Founder of Cinch Skin
Omnisend recommended I give Enflow Digital a try and they did not disappoint. They worked quickly and efficiently and made some great changes to our flows and promotional emails. They also understood our brand perfectly (both tone of voice and creative) I would recommend this team for anyone wanting a stress free partnership. Thank you!

Jennifer Freitas
Founder of The Truth Beauty Company
We hired Enflow to audit and improve our automations and the rates tell the story! And a happy story it is! We have seen a lot of growth - and recognize the potential to see more growth. Julius and his team work quickly and provide very robust reports! 1000% would I work with Enflow again!

Email marketing agency questions, answered
What does an email marketing agency do for an ecommerce store?
An email marketing agency plans, writes, designs and sends a store's emails, and builds the automated flows that send on their own. For an ecommerce store, the work covers welcome, abandoned cart, post-purchase and win-back flows, regular campaigns, list segments and revenue reports. As an ecommerce email marketing agency, Enflow Digital covers each part.
Do you require long-term contracts?
No, Enflow Digital does not ask for a long-term contract. The work runs month to month, and you can stop with notice. Before any work starts, the free audit shows what we would fix first and why. You can judge the plan before you agree to it.
Who owns the account and the designs?
You own the account and the designs. We work in your own Klaviyo, Omnisend or Brevo account, and you keep full access the whole time. The copy and designs we make for you are yours, and every flow and template stays in your account if you stop working with us.
Is the email marketing audit really free?
Yes, the email marketing audit is free, with no obligation to hire us. We review your flows, campaigns, list health, segments and sending setup. You get a written list of what to fix first, ranked by revenue potential, to use with us or on your own. Book a free strategy session to start.
Which email platform should an ecommerce store use?
The right email platform depends on your store's stack, channels and growth plan. Klaviyo suits data-led Shopify brands that want deep segmentation. Omnisend combines email, SMS and push in one account. Brevo adds WhatsApp to email and SMS and prices by send volume. We compare the options against your stack before you choose or move.
Do you work with Klaviyo, Omnisend and Brevo?
Yes, Enflow Digital works in Klaviyo and Omnisend every day and also runs Brevo accounts. We are an Omnisend Strategic Partner, a Klaviyo Partner and a Brevo Pioneer Partner. A partner program may pay us a referral fee, and we tell you when one applies. We also work in ActiveCampaign, Mailchimp and MailerLite.
Do you also run SMS, WhatsApp and direct mail?
Yes, Enflow Digital runs SMS, WhatsApp and direct mail next to your email. SMS joins your flows and campaigns, with consent handled from the first message. WhatsApp adds a third channel with consent rules built in. Direct mail automation sends letters and postcards triggered by what a customer does, such as a high-value buyer who stops ordering.
Agency, consultant or in-house team: which fits?
An agency fits a store that wants strategy, copy, design and sending handled by one team without hiring. A consultant fits a store with its own team that needs a plan or a one-off fix. An in-house team fits a brand with enough email and SMS work to keep full-time staff busy all year.
Can you take over an existing account without losing our flows?
Yes, Enflow Digital works inside the account you already have, so your flows, lists, templates and sending history stay in place. We start with an audit of what is live. Then we keep the flows that earn, and fix or rebuild the rest one flow at a time, highest revenue potential first.
How do you decide which flows to build first?
We build the flows likely to earn the most first, based on your account data. That usually means the welcome flow, the abandonment flows for cart, checkout and browse, and the win-back flow. Post-purchase, loyalty and sunset flows come next. Our guide lists 10 automated email flows every ecommerce store needs.
Is it too late to start before Black Friday?
It depends on how much time is left and how healthy your list is, so start with the free audit as early as you can. A cold or inactive list needs warming up with smaller sends before volume rises, or more emails land in spam. After the audit, we tell you what is realistic in the time left.
Who will I work with?
Every account at Enflow Digital has a named project manager, a copywriter and a designer. The project manager is your main contact, the copywriter writes your emails and texts, and the designer designs them. The founders run the agency, but the team does the account work. Meet the team on our About page.
How much of our time do you need?
We need three things from you: access, brand files and approvals. Give us access to your email platform and store analytics, share your logo, fonts and brand guidelines, and say yes or no to each draft. Your named project manager runs the day to day, from the plan to sending and reporting.
