Campaign results

Understand the metrics Sailia records after a campaign has been sent.

After a campaign is sent, Sailia records results that show what happened — how many emails reached inboxes, who engaged, and what bookings came back as a result. Use these to judge whether the message landed and to improve the next send.

Metrics Sailia records

Metric	What it measures
Sent	Total recipients the email was delivered to
Opened	Recipients who opened the email
Clicks	Total clicks on links inside the email
Failed	Sends that could not be queued for delivery
Bounced	Emails rejected by the recipient’s mail server
Spam complaints	Recipients who marked the email as spam
Unsubscribed	Recipients who opted out via this campaign
Conversions and revenue	Bookings and revenue attributed to clicks from the email

Reading the numbers

Pattern	Likely cause
High open rate, low clicks	Subject line worked, but the body or call-to-action needs improvement
Low open rate	Subject line, sender name, or send time isn’t resonating
High bounce rate	Contact list quality issue — old or invalid addresses
High unsubscribe rate	Audience was too broad, or the content didn’t match what they expected
High spam complaints	Subject feels misleading, send is too frequent, or unsubscribe is hard to find

How to use the results

• Compare the audience size and conversions side by side. A small, well-targeted audience often beats a large, vague one.
• If a metric looks unusual, check the audience filters first — most issues trace back to who received the email.
• Treat each send as an experiment. Change one variable (subject, audience, time) at a time so you can tell what made the difference.

Monitoring campaign volume

Sailia records every campaign send against the campaign-email-sent built-in meter, with the campaign’s ID, UUID, and internal name attached to each entry.

You can review volume in two places:

• Settings dashboard — a Campaign Emails Sent card shows the running total for the current month.
• Meter usage API — query campaign-email-sent for any date range to break sends down by campaign using the ExtraInfo payload.

This helps you stay within plan limits, reconcile marketing volume against billing, and spot unusually large sends before they go out.

Sent campaigns are read-only

Once sent, a campaign can’t be edited. Clone it from the campaigns list if you want to reuse the content for a future send.
