Conversion rates – how many recipients take the desired action
Bounce rates – email delivery success
Unsubscribes – audience retention insights Agencies use these metrics to optimize future campaigns and improve ROI.
B2B email marketing agencies rely heavily on data to measure success, optimize campaigns, and drive better decision-making. They focus on key performance indicators (KPIs) that reflect both engagement and conversions, helping businesses refine their email strategies over time.
✉️ 1. Open Rate
What it measures: The percentage of recipients who open an email.
Why it matters: It helps determine the effectiveness of your subject lines, sender name, and email timing. A low open rate could indicate poor targeting or unappealing headlines.
🔗 2. Click-Through Rate (CTR)
What it measures: The percentage of recipients who clicked a link within the email.
Why it matters: It shows how compelling your content and call-to-action (CTA) are. High CTRs indicate strong engagement and interest in your offer.
💼 3. Conversion Rate
What it measures: The percentage of email recipients who completed a desired action (e.g., filling out a form, requesting a demo, making a purchase).
Why it matters: It’s a direct reflection of how effectively your email drives business goals and revenue-generating actions.
🚫 4. Bounce Rate
What it measures: The percentage of emails that could not be delivered to recipients’ inboxes.
Why it matters: A high bounce rate may signal problems with your email list quality or sender reputation, both of which can harm deliverability.
📉 5. Unsubscribe Rate
What it measures: The percentage of recipients who opt out of receiving future emails.
Why it matters: Frequent unsubscribes might mean your emails are irrelevant, too frequent, or not valuable. Agencies use this data to adjust frequency, segmentation, and content tone.
📊 6. List Growth Rate (Bonus Metric)
What it measures: The net change in your email list size over time.
Why it matters: A growing email list reflects healthy lead acquisition efforts. Agencies track this to assess top-of-funnel marketing effectiveness.
