// Why it matters
Marketing that uses your real data
The best marketing uses what you already know about your customers. Codewerk Solutions builds custom marketing and email systems — or integrates tools like Brevo — connected to your shop and customer data, with segmentation, automation flows, transactional mail and analytics. We set up deliverability (SPF, DKIM, DMARC) properly so your messages actually reach the inbox.
From automated welcome and win-back flows to reliable order emails, we help you turn customer data into repeat sales — measurably.

Technology, performance and SEO
What we actually do under the hood — so you can judge the work, not just the promise.
Technology & architecture
Transactional and marketing mail through a proper sending service with SPF, DKIM and DMARC configured on your domain, bounce and complaint handling, and templates that survive Outlook. Every send is logged so you can answer why a customer says they never received the invoice.
The flows that actually earn
For B2B, the reorder reminder based on each customer's real purchase interval is typically the highest-revenue automation you can run. Then quote-expiry reminders, abandoned carts above a threshold, and a useful line inside the transactional mails that get opened anyway.
Deliverability & consent
Reputation is fragile and slow to rebuild. We separate transactional and marketing sending, honour unsubscribes immediately, and keep documented consent — because in Germany a marketing mail without consent is not a growth tactic, it is a legal risk.
// FAQ
Frequently asked questions
Yes — we sync segments and events from the shop into it via API, so the tool your marketing team likes gets the data it needs without anyone exporting CSV files by hand.
Probably, yes — structured e-invoicing is becoming mandatory in B2B, and a PDF attached to an email will not satisfy it. We can generate ZUGFeRD or XRechnung documents and archive the XML you actually sent.
On revenue attributable to the flow, not on open rates. An open rate tells you the subject line worked; it does not tell you anyone bought anything.
Almost always one of four things: SPF, DKIM or DMARC not set up correctly on your sending domain; marketing going out from the same domain and IP as your order confirmations; a list full of old addresses that bounce; or recipients marking you as spam because they never asked for it. The first three are fixable in days. The fourth is a content problem.
For order confirmations and service mail, yes. For advertising, you need a consent you can prove — per address, with a date and a source — and an address existing in your ERP is not that. There is a narrow exception for mail to your own customers about similar products, but it is narrow. Clear it with your lawyer before the campaign, not after.
Use the existing tool. Sending, templates, unsubscribes, bounce handling and reputation are solved problems, and rebuilding them costs more than the licence ever will. What is worth building is the connection: the segments and events out of your shop and ERP that the tool cannot know about. That is where the revenue is, and it is a fraction of the work.
Because one bad campaign must never stop an order confirmation from arriving. Reputation is scored per domain and IP: if a promotion collects complaints, everything sent under the same identity gets filtered — including the invoice a customer is waiting for. Separate subdomains and separate sending keep a marketing mistake a marketing mistake.
