Overview

In this article, we’ll discuss essential strategies to keep your cold emails out of spam folders and maximize deliverability. By following these tips, you can increase your email open rates, receive more replies, and ultimately grow your client base.


1. Avoid Using Spam Trigger Words

Spam filters are highly sensitive to certain words that are commonly associated with spam. These include:

  • Examples of Spam Words: "Free," "Cheap," "Urgent," and other promotional terms.

  • What to Do: Use an online spam checker tool to analyze your email copy before sending it. Remove or replace any spammy words flagged by the tool. A link to a recommended tool will be provided in the resources section.

Tip: Choose language that is professional and authentic to avoid getting flagged by filters.


2. Keep Your Email Design Simple

Emails with complex formatting or heavy visuals can also trigger spam filters. Here’s what to avoid:

  • Fancy Formatting: Avoid using special fonts, bright colors, and excessive styling.

  • Attachments and Images: Refrain from attaching large files or embedding images. Plain text emails have a higher chance of bypassing spam filters.

  • Simplified Design: Stick to simple and clean formatting. Focus on delivering a clear and concise message.

Tip: Make your emails look as natural as possible, resembling a genuine, one-to-one communication.


3. Use Natural Sending Patterns

Sending too many emails in a short period can raise red flags for spam filters. Here’s how to maintain a natural sending cadence:

  • Avoid Blasting Emails: Do not send emails too frequently or at regular, automated intervals. In Mailead.io, use the settings to add a delay of at least 5 to 10 minutes between each email.

  • Send Emails During Work Hours: Only send emails on weekdays and during typical working hours. Sending messages on weekends or during off-hours can make them appear spammy.

Tip: Create a realistic and human-like email sending schedule to reduce the risk of being flagged.


4. Maintain Consistency in Email Volume

Gradual and consistent growth in the number of emails you send is crucial. Here’s what to keep in mind:

  • Gradual Increase: Start with a small number of emails per day and slowly increase the volume over time.

  • Avoid Sudden Spikes: For example, do not jump from sending 10 emails per day in one week to 50 emails per day the next week. Such inconsistencies can alert spam filters.

Tip: Build your email volume steadily and predictably to establish trust with email providers.


Summary

By following these strategies, you can significantly improve your email deliverability and engagement rates:

  • Keep Your Language Clean: Avoid spam trigger words and use a spam checker.

  • Simplify Your Design: Use plain text and minimal styling.

  • Adopt Natural Sending Patterns: Space out your emails and avoid blasting them all at once.

  • Be Consistent: Gradually increase your email volume to build a positive sending reputation.

Remember: Keep your emails real, simple, and human-like. With these practices, you’ll see better open rates, more replies, and ultimately more clients.
