Why campaign is automatically paused<\/strong><\/h2>\n

The bounce rate in your email campaigns<\/a>\u00a0shows the percentage of emails that couldn\u2019t be delivered due to errors.<\/p>\n

Tracking this metric is important because a high bounce rate can harm your sender reputation and campaign results.<\/p>\n

\n
\"attention\"<\/div>\n
Snov.io detects bounced emails in active campaigns and pauses the sequence to protect your sender reputation. If the bounce rate for the last 100 sent emails reaches 15%<\/strong>, the campaign will automatically pause.<\/div>\n<\/div>\n
\"\"<\/div>\n

How to reduce the bounce rate<\/strong><\/h2>\n

Below, we'll outline the recommended steps <\/span>for lowering bounce rates and improving the results of your campaigns.<\/p>\n

Step 1: Verify your email list<\/strong><\/h3>\n

If your list has many unverified or Unverifiable (yellow) emails, some may bounce.<\/p>\n

\n
\"tip\"<\/div>\n
Action recommended:<\/strong> Use email verification<\/a> to identify valid, risky, and invalid emails. Yellow (risky) emails can cause bounces or delivery errors. To reduce bounce rates, send emails only to valid (green) addresses.<\/div>\n<\/div>\n

\"\"<\/p>\n

Step 2: Add email filters (only before launch)<\/strong><\/h3>\n

Apply filters to the recipient lists to automatically exclude grey and yellow emails that have a higher chance of bouncing due to their unconfirmed status.<\/p>\n

\n
\"tip\"<\/div>\n
Action recommended:<\/strong> In the Prospects<\/strong> step of your campaign settings, enable the filters under the Do not send to<\/strong>.
\nWith this option, the emails that have a selected status are automatically removed from your recipient list. If you add new prospects after the campaign starts, these filters will also work.<\/div>\n<\/div>\n

\"\"<\/p>\n

Step 3: Use SMTP connection<\/strong><\/h3>\n

If you're using Google or Microsoft email accounts, it's generally better to connect them via SMTP<\/strong> for sending campaigns. While direct integration will work, SMTP is the preferred type of connection.<\/p>\n

\"\"<\/p>\n

Step 4: Lower your daily sending limit<\/strong><\/h3>\n

Sending too many emails may appear to providers as spamming, especially if you send cold emails.<\/p>\n

\n
\"tip\"<\/div>\n
Action recommended:<\/strong> Set your daily sending limit to 50\u201360 emails. This is the recommended safe limit that won't harm your sender reputation.<\/div>\n<\/div>\n

Go to Email accounts.<\/a> Click the Edit<\/strong> icon next to your sender account. Scroll down to the Optional settings<\/strong> section. Under the Daily sending limit<\/strong> tab, adjust the Messages per day<\/strong> value.<\/p>\n

Also set longer, random intervals between emails in email account settings. To make your sending pattern look more natural to providers, enable Random delay between emails<\/strong> and set it to 300\u2013600 seconds (5\u201310 minutes).<\/strong><\/p>\n

\"\"<\/p>\n

Step 5: Disable tracking or set up a custom domain<\/strong><\/h3>\n

Tracking helps you collect statistics and monitor engagement reports<\/a>, but it can also impact email deliverability.<\/p>\n

\n
\"tip\"<\/div>\n
Action recommended: <\/strong>If you use open or link tracking, consider disabling it or setting up a custom tracking domain to avoid any potential negative effects.<\/div>\n<\/div>\n

If your sequences depend on tracking for checking conditions<\/a>, a custom domain is a must-have. This guide will help you set it up.<\/span><\/a><\/p>\n

\"\"<\/p>\n

Step 6: Check domain health and test deliverability<\/strong><\/h3>\n

To identify potential issues with your email infrastructure, use our deliverability check<\/a>.<\/p>\n

It helps you troubleshoot your domain\u2019s DNS settings, email content, and other factors that may cause bounces or affect email placement.<\/p>\n

You can test your sender email accounts and receive personalized tips to fix any identified issues.<\/p>\n
