When a large e-commerce platform takes a significant stake in a maker of email marketing tools, it is easy to read it as just another financial investment. Usually it is more than that. Platforms that host online stores and the tools that help merchants contact their customers depend on one another. A strategic investment reflects that mutual need, and understanding it helps merchants decide which tools to build their business on.

What email marketing tools do for a store
Online shops live and die by repeat business. Email marketing tools collect data about shoppers, such as what they browsed, bought or abandoned, and use it to send relevant emails and text messages without manual work. A new customer receives a welcome sequence. Someone who left items in a cart gets a reminder. A buyer of a consumable product is nudged to reorder when they are likely to run out.
Done well, these messages feel helpful. Done badly, they feel like spam. The difference lies in segmentation, timing and restraint.
Why a platform would invest in email marketing tools rather than build
A platform could create its own email marketing tools, and many offer basic ones. But specialized companies often move faster and go deeper. Investing is a way to align with a partner without rebuilding everything. It can secure close integration, ensure that the best tools work smoothly with the platform, and share in the upside if the partner grows.
There’s a competitive logic too. If merchants can easily use a best-in-class tool, they are more likely to stay on the platform. Being the home of great marketing software is part of the platform’s appeal.
What merchants may gain
- Tighter integrations, with product, order and customer data flowing in near real time
- Easier setup, with fewer custom connections to maintain
- Shared roadmaps that reflect common merchant needs
- Possible bundled offers, partner programs or smoother billing
- Greater confidence that the tool will remain supported
These are plausible benefits, not guarantees. Always check what is actually announced and how it applies to your business.
What merchants should still watch
A platform’s backing of a vendor does not mean it is the right fit for your store. Consider cost: advanced email marketing tools usually price by the number of contacts or messages, and costs can climb as your list grows. Compare plans at your realistic list size, not just the starting tier.
Think about lock-in. The more your customer data, flows and templates live in one tool, the harder it is to leave. Ask about exporting contacts and campaign content.
Check deliverability, which is how often your emails reach the inbox rather than spam. It depends on sending practices, authentication, list quality and the vendor’s reputation.
And consider independence. Email marketing tools closely tied to one platform may be less useful if you later add a second sales channel or move to a different store system.
Principles for better store messaging
Whatever email marketing tools you use, the basics matter more than the brand name. Get permission before sending. Keep lists clean by removing inactive addresses. Segment: a first-time buyer and a loyal customer need different messages. Make unsubscribing easy; it protects your reputation. Test subject lines and timing, but change one thing at a time. And measure revenue and unsubscribes, not just opens, since privacy features have made open rates less reliable.
Respect regional privacy rules about consent and data. Marketing laws differ by country, and merchants are responsible for compliance even when a tool helps.
What strategic investments signal
For investors and observers, such deals can signal where the industry is going. Commerce is increasingly about owning the customer relationship through first-party data and direct channels, rather than depending on rented attention from advertising networks. Email marketing tools that help merchants turn one purchase into many are strategic for platforms because they increase the lifetime value of each store.
They also reflect a broader trend of platforms building ecosystems of partners, giving merchants a short list of trusted tools instead of an overwhelming marketplace.
How to choose among email marketing tools for your own shop
Start with your needs: email, text, or both? How big is your list? Which platform are you on? Then try a free plan or trial and build one flow, such as an abandoned cart message, to see how easy it is. Look at reporting and support. Talk to other merchants in your category, who often have the most honest views.
Email marketing tools beyond the inbox
Email is only one channel. Many merchants now blend it with text messages and chat, an approach we discuss in social commerce explained: selling through chat, not storefronts. The point is the same everywhere: reach shoppers where they already spend time, and respect their time.
For the platforms, the bigger question is how marketplaces and storefronts keep merchants loyal, a topic covered in how online marketplaces work and why big retailers buy them. If you want a neutral primer on the channel itself, read about email marketing.
Summing up
A strategic stake in one of the email marketing tools tells you that the platform sees customer communication as central to merchant success. As a merchant, use that as a hint, not a verdict. Choose the software that fits your business, protect your data, and keep the focus where it belongs: sending fewer, better messages to people who actually want them.
