This structured process ensures Swipe One delivers high-quality email performance, safeguards its reputation, and helps users succeed with their campaigns while adhering to best practices.

1. Why Email Warmup Is Necessary

Email warmup is a critical process to ensure the success of email campaigns and safeguard the reputation of the Swipe One platform. Without a warmup process, new accounts risk being flagged as spam by Internet Service Providers (ISPs), leading to poor deliverability and damage to sender reputation.

The email warmup process addresses these challenges by:

  • Gradually building trust with ISPs through consistent and reliable email behavior.

  • Ensuring high deliverability rates for new users.

  • Preventing misuse of the platform, both intentional and unintentional.

  • Providing safeguards for entrepreneurs and business owners who may not be fully aware of email best practices.


2. How It Works

Initial Sending Rate

  • All new accounts start with a sending limit of 100 emails per hour.

  • This limit increases dynamically based on the bounce rate (<5%) and complaint rate (<0.1%).

Progressive Rate Increase

  • Sending limits grow only if key metrics meet acceptable thresholds:

    • Bounce Rate: Ensures users are sending to verified and clean email lists.

    • Complaint Rate: Demonstrates that the content and recipients align with email best practices.

  • Open rates or engagement metrics are not factored into the warmup process.


3. Handling Different Types of Email Sends

Triggered Emails vs. Bulk Emails

  1. Triggered Emails: Emails sent through workflows triggered by events such as "Order Processed" or "Form Submitted" are naturally sporadic in nature and typically low in volume. These emails are not significantly affected by rate limits because they occur individually or in small batches.

    • Example: An email sent to a customer confirming their order.

  2. Bulk Workflow Sends: Events like "Entered a Segment" or "Tag Added," which apply to large groups of contacts, trigger bulk email workflows. These are subject to the current rate limits to ensure reputation safety.

    • Example: Sending a promotional email to 10,000 contacts added to a new segment.


4. Preventing Misuse

Swipe One employs multiple strategies to prevent abuse and ensure platform-wide email success:

  • Common Unintentional Misuses:

    • Invalid Email Lists: Sending to unvalidated lists can result in high bounce rates. This often happens when users:

      • Collect email addresses through forms without sufficient validation.

      • Buy lead lists containing outdated or cold email addresses.

    • Form Issues: Forms that don’t validate entries may allow users to submit incorrect information, leading to undeliverable emails.

  • Safeguards in Swipe One:

    • AI-driven spam detection to identify risky campaigns.

    • Mandatory email warmup for all accounts.

    • Verification of email addresses and domains:

      • SPF and DKIM Records: Validate sender domains for authenticity.

      • Support for Reoon API Key: Users can integrate their own tools for enhanced email validation and checks.


5. Marketing Emails vs. Sales Emails

Understanding the difference between marketing and sales emails is vital to comply with laws like the CAN-SPAM Act and ensure campaign success.

Marketing Emails

  • Sent to a broad audience, often promoting a product, service, or event.

  • Examples:

    • Announcing a new product launch.

    • Offering a Black Friday discount.

  • Must follow these rules:

    • Include a clear unsubscribe option.

    • Display the sender’s business address.

    • Avoid misleading subject lines.

Sales Emails (Cold Outreach)

  • Personal, one-on-one emails sent to potential customers to initiate contact.

  • Examples:

    • "Hi, I saw your website and thought Swipe One could help manage your customer outreach."

  • Important Guidelines:

    • Use personal inboxes (e.g., Gmail, Outlook) rather than bulk email systems.

    • Do not promote offers directly.

    • Ensure the email provides value and establishes trust before selling.

What’s Allowed in Cold Outreach?

  • ✅ Introducing your business.

  • ✅ Offering to solve a problem or provide information.

  • ❌ Directly promoting discounts or offers.

  • ❌ Misleading or deceptive messages.

Example: Acceptable: “Hi [Name], I noticed you manage a growing e-commerce business. Swipe One could help automate customer engagement. Would you be open to a quick chat?” Unacceptable: “Hi [Name], Sign up for Swipe One today and get 50% off!”


6. Best Practices for Users

To ensure high deliverability and avoid complaints:

  1. Use Verified Email Lists:

    • Validate email addresses with tools like Reoon API integration.

    • Avoid sending emails to purchased or scraped lists.

  2. Segment Contacts Smartly:

    • Group contacts based on engagement history or preferences.

    • Avoid sending marketing emails to cold prospects.

  3. Craft Relevant Content:

    • Personalize messages to the recipient's interests or behavior.

    • Use clear subject lines and avoid spammy language.

  4. Comply with Legal Guidelines:

    • Follow the CAN-SPAM Act for marketing emails.

    • Ensure all cold outreach emails adhere to acceptable practices.


7. What Swipe One Does to Maintain Best Practices

  • AI-Powered Spam Detection: Identifies campaigns likely to be flagged by ISPs.

  • Mandatory Warmup: Ensures all users build sender reputation gradually.

  • Domain Authentication: Supports SPF and DKIM records for email verification.

  • Email Validation:

    • Verifies email addresses to prevent bounces.

    • Provides integration with Reoon API for enhanced checks.

8. Email Health Metrics

Swipe One includes a dedicated Email Health tab under Account Settings where users can monitor their overall email sending performance. This feature ensures transparency and helps users identify areas of improvement.

Key Metrics Displayed:

  1. Bounce Rate: Tracks the percentage of undeliverable emails.

  2. Complaint Rate: Monitors how often recipients mark emails as spam.

  3. Total Emails Sent.

Account Reviews and Suspensions:

  • Under Review: Accounts are flagged if:

    • Bounce rates exceed 5%.

    • Complaint rates exceed 0.1%.

    • Consistent delivery issues across campaigns.

  • Suspension: Accounts are temporarily disabled if health metrics remain poor after multiple warnings or reviews.

    • Users can work with Swipe One’s support team to resolve issues and reinstate their account.

Proactive Alerts:

  • Users receive automated alerts and recommendations when health metrics deviate from acceptable thresholds.

    • Example: "Your recent campaign had a bounce rate of 7%. Consider verifying your list using Reoon API integration."
