📩 Why do my emails arrive as spam?

When you send an email and it ends up in the recipient’s spam folder, it may be due to several technical and reputational factors. Below I detail the most common ones and how to solve them.

---

🚫 1. You are using a new domain without reputation

When a domain is new, email providers (like Gmail, Outlook, etc.) don’t know about it yet, therefore, they are more strict when classifying your messages. 📌 Solution: Use your email normally and avoid suspicious behavior during the first weeks. reputation is built over time.

---

📛 2. Your domain has been flagged for spam in the past

If you have ever sent mass, promotional emails without permissions or been reported by users, your domain goes on blacklists. That means your legitimate emails also go to spam.

📌 Solution: Avoid sending spam and correct previous errors. If your website was compromised, change passwords and make sure it is updated and free of malware.

🔒 3. Your email is not well authenticated (DKIM and SPF)

DKIM and SPF records help destination servers verify that you are a legitimate sender. If they are not configured correctly, your emails lose credibility.

📌 Solution: From your control panel (DirectAdmin or cPanel), make sure these records are active in your domain’s DNS. 👉 At miHosting.com, you can follow this explanatory video to configure them correctly.

🧠 4. You use suspicious words or formats

Anti-spam filters detect certain words or formats as red flags. Avoid the following:

• Words like “free”, “viagra”, “urgent”, “click”, “offer”
• Excessive use of capital letters, exclamation marks (!!!), or bright colors
• Emails without subject or with only an image as content
• Very empty phrases like “hello” or “this is a test”

📌 Solution: Write emails with clear, formal and professional content. Always include a descriptive subject.

🖥️ 5. Your computer could have viruses or Trojans

If your device is infected, it may be sending emails automatically without you noticing. This damages the reputation of your domain and your IP.

📌 Solution: Check your computer with an updated antivirus and avoid sending emails from compromised devices.

---

📎 6. Poorly managed attachments

Sending attachments without context, in unusual formats or without compression also raises suspicion.

📌 Solution: Send the compressed files (.zip or .rar) and always accompany them with a clear text explaining what they contain.

---

🤝 7. Your recipients don’t know you

If your recipients do not have you on their contact list or have never interacted with you, your email is more likely to end up in spam.

📌 Solution: Ask your contacts to add your email address to their address book. That improves your deliverability in the future.
