Digital Prepping: How to Secure Your Email Infrastructure in an Uncertain World

In a time of increasing digital instability, geopolitical tension, and growing dependence on large global cloud providers, taking control of your email infrastructure has never been more important.
We call it Digital Prepping – making sure your business stays connected, compliant, and resilient, no matter what happens around you.

Why Digital Prepping Matters

Imagine your cloud-based email service is disrupted by downtime, restrictions, or policy changes. If your business relies entirely on one provider, you’re vulnerable.
Digital Prepping isn’t about fear – it’s about preparedness.

Choose Local go Global

✅ Always online – our systems are built for high uptime and stability.
✅ Independent of Big Cloud – hosted entirely in Denmark and 100% GDPR-compliant.
✅ Close to the market – local support and technical know-how, when you need it.
✅ Dedicated infrastructure – choose shared or dedicated IPs depending on your volume.


Outdated platform infrastructure = Higher Risk

Without modern authentication like SPF, DKIM, and DMARC, your emails could easily be flagged as spam – or blocked altogether.
Today, it’s not just about sending emails – it’s about sending them securely, correctly, and with control.

Digital Prepping Is About Smart Choices

Make sure you:

Stay ahead of new compliance rules from Microsoft, Google, and Yahoo.
Protect your sending reputation and domain identity.
Avoid overdependence on cloud platforms that can change terms or performance overnight.

Once, a Stamp on the Envelope Was Enough

In the old analog world, we sent physical letters for more than 100 years based on a stamp with a value indicating the letter's weight, size, and the physical distance the letter had to travel to reach the recipient.
At the post office, the stamp was marked with a postmark approving that the postage was correct, and the letter could be sent. If not, it would be returned or given penalty postage. Enough about that trip down memory lane.
Today, we send billions of emails daily, of all kinds and with varying content. The analogy is quite simple: these emails also need a "stamp" to reach the inbox on the other end. Today, these “stamps” are called SPF, DKIM, and DMARC. In short, these are identity and verification mechanisms that ensure your email is not classified as spam and thus reaches the recipient.
mySMTP has launched a tool you can use for free to check your email's ability to reach the inbox. You simply copy the auto-generated email address into the email you want to check and then see the result in the browser window. There might be some things to fix to ensure optimal delivery.

BIMI – ny email certificering på vej.

Du kender allerede SPF, DKIM og DMARC. Nu kommer BIMI der står for Brand Indicators for Message Identification.
BIMI er en en ny mekanisme der skal verificere at det brand der sender emails til dig også er det rigtige brand og ikke et spoofed eller andet scam. Det foregår ved at der vises et brand logo udfor afsenderens navn i toppen af emails i stedet for f.eks. et billede eller typisk to bogstaver som initialer.

BIMI skal indsættes som en DNS TXT record, og du skal have gyldige SPF, DKIM, DMARC records for at det bliver annonceret korrekt
Der vil selvsagt være en masse fordele ved denne certificering når den endelig bliver rullet fuldt ud. PT er det kun OATH (Yahoo, AOL, Verizon) der kan vise brand logoer med en BIMI record i indboksen. Gmail og Hotmail m.fl. bakker op, og der kan forventes en global udrulning i løbet af 2020.
Som brandejer vil man have bedre styring på at logo vises grafisk korrekt og ensartet. Email modtageren vil sandsynligvis åbne flere emails når man føler sig sikker på det ikke er scam og det vil igen medføre bedre åbnings og klik rater. Fremtiden vil være no brands logo – no trust.

G suite is a paid solution from Google, including sending emails.
You might should worry a little regarding the IPs used for sending emails when it shows up on 20 Blacklists.

Gmail use themselves SORBS as a preferred RBL to check for reputation problems, this is just funny how you then cannibalize you own sending reputation.
