What do participation limits do?

Qualifio participation limits allow you to limit entries in campaigns and control who can participate and how many times your campaign can be taken part in.

Why limit campaign participations?

Limiting or capping campaign participations can be extremely useful. If you’re seeking brand awareness, you may want as many people as possible to enter. But, for example, if you’re running an online sampling campaign, you can limit the number of participations so that only a specific amount of people can register.

While limiting participations is definitely something worth considering, it’s up to you to decide what makes the most sense for your particular campaign. Ultimately, single or multiple participations depend on the objective of the campaign 😉

When it comes to limiting the number of participations, there are a few different options. Here’s a quick overview of what they mean:

Individual participation limits

One-participation limit

Everyone is limited to a single participation.

What exactly is being restricted? This limit is based on the combination of one’s first name, last name and email address, plus a cookie.

Individual limits based on IP addresses, email addresses, or phone numbers

Limit participants to a defined number of participations.

  • Limit participations by IP address: only one person using an IP address can take part in the campaign. If spouses, roommates or colleagues share the same home/office and internet service, only one of them could be able to participate, while the others might be blocked. However, this is a useful option for limiting participants to your anonymous campaign, which may not have any other identifying information. Note: depending on one’s internet provider or plan, an IP address might remain the same over time or it might change at certain intervals.
  • Limit participations by email address: each email address can participate once. This means that if a participant has two email addresses registered, they could enter your campaign twice.
  • Limit participations by phone number: each phone number can participate once. This means that if a participant has two phone numbers registered, they could enter your campaign twice.
Tip: Include any participation limits in your contest rules. This way, it doesn’t matter if a participant uses a different name, IP address, email address, or phone number – they can still only enter as many times as permitted by the rules.

Individual limits with frequency capping

Limit how often participants can enter your campaign. This type of participation limit means that each user, personally, can only enter once per time period. They can enter multiple times, but they have to wait between participations.

Note: Just like the one-participation limit, these are based on the combination of one’s first name, last name and email address, plus a cookie.

Specify a time period for which the participation limit applies by selecting one of the options below:

Rolling time periods

  • One participation every 60 minutes: one’s participations must be at least 60 minutes apart from one another. So if one enters at 10:08, they cannot enter again until 11:09.
  • One participation every 24 hours: one’s participations must be at least 24 hours apart from one another. So if one enters at 15:18 on Monday, they cannot enter again until 15:19 on Tuesday.
  • One participation every 7 days: one’s participations must be at least 7 days apart from one another. So if one enters at 9:00 on Monday, they cannot participate again until 9:01 on the following Monday.

Calendar periods

  • One participation every hour: one can participate once per hour, at any time between hh:00 and hh:59. Meaning that if one enters at 13:04, they will not be able to enter again until 14:00, as the hourly limit resets at hh:00.
  • One participation every day: one can participate at any time between midnight and 23:59 the same day. So, one could theoretically enter once at 23:59 on Monday and again one minute later at midnight on Tuesday and have both participations count. The daily limit resets at midnight.
  • One participation every week: in this case, if one enters your campaign on Wednesday, no more participations will be accepted for the rest of the week. The weekly limit resets at midnight on Monday.
ℹ️ Note: With these options, you cannot choose a maximum number of participations per time period.

Custom limit (based on secure token)

Limit participations based on custom actions. To do this, you can fetch external information to define in real time who can participate in your campaign.

Collective participation limit

Limit the total number of participations.

First, you’ll need to activate the Limit collective participations setting.

Upon activation, you will see that it’s all easily configurable with comprehensive options!

Now, do you simply want to limit the total number of participations allowed in your campaign? For example, say you need to create an event RSVP form with limited seats. To do this, just enter the number of participations you want to allow.

Once you’ve done that, you can further configure your collective participation limit with the options below.

Collective limits with frequency capping

So knowing the total number of participations allowed is the first step, but there’s another step to consider, too: how often is that limit going to reset? This is the time period for the collective limit.

You can establish limits on the number of participations for a monthly, weekly, daily, or hourly time period. To do this, expand the forever dropdown and choose with a regular frequency.

For example: You may want to place a weekly participation limit. For this specific example, let's imagine that you have set the weekly limit to 480 participations. And your week starts at 7:00 on Wednesday.

Capture d’écran, le 2023-12-13 à 11.23.12.png

With this setting in place, the system will allow 480 participations from the start date of your campaign until 7:00 on the first Wednesday following it. Then, we will allow 480 more until 7:00 on the Wednesday after that, and so on.

This is particularly useful in the case of a sampling action, or anytime you want to ensure that participations are spread evenly over time.

👋🏼 Heads up! The time of the day will be calculated based on the time zone defined in your website settings.

Global capping

Additionally, the global cap controls the maximum number of participations a campaign can get across channels.

Global capping overrides frequency capping settings. This means that if your campaign has reached the global capping limit on day 5 out of 7, users will not be able to participate for the other two days.

  5. When your setup looks good, click Save.

How are limits enforced when I delete participations?

When you delete participations in the statistics of your campaign, it's important to note that the limits are not directly affected by this action. The participation counter increments by one each time a user participates in the campaign. However, the participation count does not decrease when individual entries are deleted. In other words, the system does not retroactively adjust the count based on deletions, except if you completely reset ("purge") the campaign statistics. Keep in mind that this process will wipe out all existing data related to the campaign.
