Secure Summer Operation: How to Prevent Cybercriminals from Impersonating Your Emails and SMS While Your Customers Are on Vacation

Picture the scene: you’re on a sun lounger, with a cold smoothie in one hand and your phone in the other. The sun is just warm enough, the sound of the sea waves in the background, and your brain is officially on vacation. You don’t want to know anything about spreadsheets, endless Zoom meetings, or that annoying client who always writes at seven in the evening. You just want to disconnect.

Well, that’s exactly what’s happening to your customers right now.

Summer is that magical time when we all let our guard down. We become suspiciously trusting, reading messages out of the corner of our eye while eating a double-scoop ice cream and clicking on links almost without looking. And here’s the cold shower: cybercriminals don’t take vacations. In fact, they hate winter and love summer as much as you do.

When people are relaxed and businesses are running at half speed due to vacation shifts, hackers take advantage to make their August. Through fake emails (phishing) and fraudulent text messages (smishing), they try to impersonate cool brands to scam users.

If you don’t protect your communication channels, the bad guys can use your business name to deceive your audience. The result? A tremendous reputation crisis that will throw away the trust you’ve worked so hard to build.

That’s why today officially kicks off the Secure Summer Operation. We’re going to see why email and SMS are actually two hyper-secure channels if you know how to use them, and we’ll tell you about the legal bombshell coming right after the holidays. Dive in!

The Psychology of “Beach Mode”: Why Summer is the Goldmine for Scams

Why do cyberattacks increase dramatically during the hot months? It’s not because hackers drink more coffee, but because we enter “mental airplane mode.”

In the office, with the air conditioning on, your brain is on alert mode. If you receive a strange email, you raise an eyebrow and suspect. But under the sun, in a rush to pack or distracted by being out of routine, we become an easy target. Scammers exploit that vacation urgency with hooks that hurt:

• Fake airline SMS saying your flight to Ibiza has been canceled (instant panic).
• Emails mimicking Booking requesting immediate payment to avoid losing the villa you booked.
• Urgent messages from Correos warning that your package with new swimsuits is on hold.

If your company sends legitimate emails or SMS but doesn’t take care of technical security, your subscribers might confuse your real messages with a scam. Or worse: if your domain isn’t locked down, a hacker could send thousands of fraudulent emails signing with your name.

Bulletproof Emails: The Three Bouncers of Your Domain

Sometimes there’s so much talk about the dangers of the internet that it seems like doing marketing is like walking through a minefield. Not at all! Email marketing campaigns are still the life of the party, but they need you to activate their invisible shield.

Behind every email you send are three technical bouncers telling Gmail, Outlook, or Yahoo: “Hey, this email is legit, it comes from the real company and not from an impostor with a fake mustache”. If you haven’t set them up in your email provider yet, your summer emails will go straight to the penalty zone: the spam folder.

Meet the triple alliance that will save your summer:

• SPF: It’s like the VIP guest list at the door. It tells the whole world which servers and tools (like Acumbamail) have your official permission to send emails using your name.
• DKIM: It’s the equivalent of a digital wax seal. A mathematical key that ensures the email hasn’t been tampered with or “hacked” on its way from your computer to the client.
• DMARC: It’s the head of security at the door. This protocol tells Gmail what to do if someone tries to impersonate you and doesn’t pass the SPF or DKIM filters. It gives the direct order to destroy the fake email or send it to the trash so your client never sees it.

Having this trio set up is vital. Email filters have become incredibly strict; if you do your homework, your delivery and open rates will stay sky-high while you take a dip.

The SMS Channel is Fortified by Law: The September 15 Bombshell

If email has strong walls, SMS is about to become a real fortress. SMS sending is the undisputed boss of effectiveness thanks to its spectacular 98% open rate. Everyone opens a text message; it takes us less than three minutes to read it. Precisely for this reason, scammers have tried to sneak into this channel in a bad way.

But their luck has run out in Spain.

Right after the holidays, on September 15, the new and revolutionary regulation from the Government and CNMC to combat fraud comes into full force. This law introduces a radical change: the creation of the Official Alias Registry.

What does this mean for your business? You’ll see it’s fantastic news:

1. Automatic Impostor Blocking: Starting September 15, telephone operators (Movistar, Vodafone, Orange…) will by default block any mass SMS whose text sender (that name that appears at the top, like “MY-STORE”) is not verified in the official database.
2. End of Impersonations: No one will be able to send a fraudulent SMS using your brand name to steal data because the operators’ systems will stop it before it leaves the pipe.
3. SMS Returns as the King of Trust: By cleaning up the market of junk messages and scams, your customers will open your SMS with complete peace of mind.

Your Action Plan for This Summer: Don’t wait until September with the back-to-school rush and a trembling inbox. On professional platforms like Acumbamail, you can already register and validate your custom text sender. Set up your campaigns and protect your aliases before going on vacation, and you’ll ensure that your communications continue to flow smoothly when the new term begins.

Survival Guide: How to Send Messages Without Looking Suspicious

Besides technology and laws, common sense is your best lifesaver. To ensure your summer campaigns exude good vibes and professionalism, engrave these three golden rules in your mind:

• Ban Public Link Shorteners: The bad guys love free link shortening tools (like Bitly) because they serve to hide fake web pages. If you use these shorteners in your SMS to save space, the spam filter or your own client will distrust you. Always use links that display your own web domain or solutions that allow you to customize the short URL with your brand.
• Tone Down the Panic: The language of digital fraud always seeks a quick heart attack (“Immediate action required!”, “Account suspended”, “Avoid charges”). If you use too aggressive a tone to sell your summer sales (“LAST NOTICE OR YOU LOSE EVERYTHING!”), you’ll scare your subscribers. Opt for a fresh, relaxed, summery, and above all, human tone.
• Beware of Pirate Wi-Fi at the Beach Bar: Working remotely by the sea sounds like a movie, but open and password-free Wi-Fi networks at hotels or beach cafes are dangerous. They are the perfect setting for cybercriminals to steal your marketing platform passwords. Share data from your mobile or use a VPN, and always enable two-factor authentication (2FA) on your Acumbamail account.

Conclusion: A Peaceful Summer is Planned Today

Cybersecurity in summer is not about becoming paranoid or freezing your marketing campaigns until the leaves fall from the trees. On the contrary: it’s about taking advantage of the fact that email and SMS are two incredibly secure channels if treated with a bit of technical and legal care.

Spend a few minutes this week reviewing your domain records, securing your SMS sender for the September 15 change, and reminding your team of a couple of basic guidelines. Once that’s done, you can lie under the umbrella with absolute peace of mind knowing your business and customers are safe.

Happy, safe, and profitable marketing summer!
