The Problem With Using Regular Email
and Texting for Business

Most business communication happens over email and text messages. Contracts, client information, financial details, internal strategy — all of it flowing through tools that were never designed with privacy or security in mind. Understanding exactly what that means for your business is the first step toward doing something about it.

What "Unencrypted" Actually Means

Think of a standard email like a postcard. The message is written on the outside, visible to every postal worker who handles it along the way. Contrast that with a sealed envelope — the contents are hidden from everyone except the intended recipient.

When an email is unencrypted, the content of your message is readable in plain text as it travels across the internet. It passes through multiple servers before it reaches the recipient's inbox. At any point along that route, someone with access to those servers — legitimately or not — can read exactly what you wrote.

Most standard email services (including common business accounts) encrypt the connection between your device and their servers, which is better than nothing. But the content is often stored and accessible by the email provider themselves, and in many cases is readable at multiple points in transit.

Who Can Actually Read Your Emails

This is the part most people do not think about. Here is a realistic list of parties who can potentially access the content of a standard business email:

  • Your email provider. Companies like Google and Microsoft can read the contents of emails stored on their servers. Their terms of service say so. They use this access for a variety of purposes, including advertising and compliance.
  • Hackers on the same network. If you access your email on an unsecured Wi-Fi network — a coffee shop, an airport, a hotel — anyone else on that network with the right tools can intercept your traffic.
  • Attackers who compromise a mail server. If any of the servers your email passes through are compromised, your message can be captured and stored without your knowledge.
  • Law enforcement with a subpoena. Government agencies can compel email providers to hand over the contents of your account. No notification to you is required in many circumstances.
  • Anyone with access to your recipient's account. Even if your email was secure in transit, it is only as safe as wherever it ends up — and most recipients use the same unprotected email systems you do.

Text Messages Are Even More Exposed

Standard SMS text messages are, if anything, worse than email from a privacy standpoint. They are transmitted through carrier networks and stored on carrier servers for years. They are not encrypted end-to-end under any circumstances on the standard SMS protocol.

Beyond carrier storage, SMS has a specific vulnerability worth knowing about: IMSI catchers, sometimes called stingrays, are devices that impersonate cell towers and intercept messages in real time. They are used by law enforcement and, increasingly, by sophisticated private actors. If a conversation is sensitive enough, someone with the right equipment can intercept it.

There is also SIM swap fraud, where an attacker convinces your carrier to transfer your phone number to a SIM card they control. Once they have your number, any text-based verification codes — including two-factor authentication codes — go to the attacker instead of you. Financial institutions and business accounts fall to this attack regularly.

One important note: iMessages between two Apple devices are encrypted end-to-end — but only when both devices are using iMessage (blue bubbles). When a message falls back to SMS (green bubbles), all of those protections disappear.

What Is Actually at Risk in Your Business

Consider what flows through your email on a typical week. Client contact information. Case details or account information. Payment requests and banking details. Legal correspondence. Internal strategy discussions. Personnel matters. Any of that, in the wrong hands, represents a liability — financially, legally, and reputationally.

Many small businesses are also bound by regulations that specifically require them to protect client data. Healthcare providers face HIPAA. Businesses handling payment card data face PCI DSS requirements. Legal and financial professionals have their own regulatory frameworks. Using standard email for sensitive communications may put you in violation of those requirements whether you realize it or not.

In 2023, a single compromised email account cost the average small business $137,000 in direct losses — not counting legal fees, regulatory penalties, or reputational damage.

What to Use Instead

End-to-end encryption is the standard you are looking for. It means the message is encrypted on your device before it is sent, and can only be decrypted on the recipient's device. No one in between — not the service provider, not a server admin, not a government agency with a warrant — can read the content.

  • For messaging: Encrypted messaging platforms exist specifically for this purpose. When implemented correctly, they provide strong protection for day-to-day communications without significantly changing how your team works.
  • For email: Encrypted email services store messages in encrypted form that even the provider cannot read. For highly sensitive communications, this is a meaningful upgrade over standard email.
  • For your team: The tools need to be consistent. One employee using secure communication while everyone else uses standard email eliminates most of the protection. A full switch is what actually works.

This is what Covenant Ghost deploys for our clients — encrypted communication systems that work across your entire team without requiring any technical expertise to use day to day. Your people send messages and emails the same way they always have. The protection happens underneath.

Action Steps

  1. Identify what categories of sensitive information currently travel through your standard email and text messages.
  2. Check whether your business has any regulatory requirements around data privacy — HIPAA, PCI DSS, state privacy laws — and whether your current communication methods comply.
  3. Stop sending sensitive client data, financial details, or internal strategy over standard SMS immediately.
  4. Evaluate encrypted communication options for your team. Any solution needs to cover your whole team to be effective.
