Campaign metrics — email, SMS and WhatsApp | Nevent

Sending a campaign without measuring its impact is like putting on an event without tracking ticket sales: technically possible but commercially pointless. Nevent’s campaign metrics tell you exactly what worked, what didn’t and how much money each message generated.

What is open rate and what is a good benchmark?

Section titled “What is open rate and what is a good benchmark?”

Open rate is the percentage of recipients who opened your email relative to the total number sent. In live events marketing, a healthy open rate for segmented audiences typically sits between 25% and 40%. Unsegmented mass sends rarely exceed 15–20%.

According to Mailchimp’s industry benchmarks for the arts and entertainment sector, the average open rate is 21.2%. Promoters applying behavioural segmentation in Nevent routinely achieve values between 30% and 50%.

What is the difference between click rate and conversion rate?

Section titled “What is the difference between click rate and conversion rate?”
  • Click rate: the percentage of fans who clicked any link in the email (regardless of whether they then purchased).
  • Conversion rate: the percentage who completed the target action (normally, buying a ticket) after clicking.

Imagine you send a campaign to 10,000 jazz fans in Barcelona. 35% open the email (3,500 fans), 12% click the purchase link (1,200 fans) and 4% complete a purchase (400 fans). You have an open rate of 35%, a click rate of 12% and a conversion rate of 4%.

ROAS (Return On Ad Spend) for a campaign measures how many pounds of revenue are generated per pound invested in that campaign. For email and SMS campaigns, the “spend” includes the cost of the tool plus content production time.

A ROAS of 10 means that for every pound invested in the campaign, you generate £10 in ticket sales. For well-segmented email campaigns targeting event ticket buyers, ROAS values between 15 and 40 are achievable, depending on the sector and audience maturity.

You can view metrics for each channel separately or compared side by side:

ChannelTypical open rate in sectorBest for
Email20–35%Detailed communications, early-bird sales
SMS85–95%Urgency messages, last tickets, reminders
WhatsApp70–90%VIP fans, close and personalised communication

Imagine you promote electronic music events in Madrid and launch three campaigns for the same event: one via email to 8,000 fans, one via SMS to 2,000 fans and one via WhatsApp to 500 VIP fans. With Nevent you can see in a single report which of the three generated the most attributed revenue and which had the best ROAS — so you can prioritise the right channel for the next event.

  • Open rate, click rate and conversion rate form the basic funnel for each campaign
  • Attributed revenue tells you how much money each send actually generated, not just who opened it
  • ROAS compares profitability across campaigns and channels
  • Unsubscribe rate and bounce rate are early signals of list quality issues
