We recently concluded the analysis of a campaign that focused upon generating funds on a single day. Of course, days leading up to “day zero” (or the campaign launch date), we leveraged our house email files to send “save the date” type email campaigns, and lead-ins that promoted the one-day fund raising event.

Throughout the campaign, there was a perception that by sending more email messages throughout the campaign to our house file, that we would negatively affect our campaign results.

We heard several arguments attempting to dissuade us from sending multiple messages, but we worked with the client to assure them that our tests indicated that we would be okay.

Revenue per hour

The campaign revenue per hour chart shows, with the red lines, each email message that we had sent throughout the campaign timeline, and revenue collected per hour of the campaign with the blue line.

The chart above is the “Revenue per hour” chart that outlines the revenue that we collected each hour that the campaign was live (represented by the blue line) and the email messages that we sent throughout the campaign timeline (indicated in the vertical red lines).

As you can see, each email that we sent immediately sparked a burst of revenue collected for several hours thereafter.

This is exceptionally interesting to me, considering my personal feeling was that we could possibly cause unwanted attrition to the email file size that we had worked so hard to build, while also “turning off” the audience in the email recipient list. It turns out I, and our clients, were wrong.

This is just another interesting example of the fact that a marketer’s intuition is always trumped by cold, hard data.

So, if you’re promoting a one-time event (a webinar, fund raising campaign, etc.) — definitely leverage more emails than less, as your audience will not be turned off by your consistent messaging.

All the best,
