User is a Part of an Experiment

Overview

The "User is part of the experiment" status is an informational message generated by Meta. It indicates that the recipient is currently included in one of Meta's controlled experiments or phased feature rollouts.

As part of these experiments, Meta may temporarily change how messages are processed or delivered for a small group of users.

Important: This status is generated entirely by Meta. It does not indicate an issue with your Picky Assist account, WhatsApp Business Account, or phone number configuration.

What Does "User is Part of the Experiment" Mean?

Meta regularly tests new features, performance improvements, and messaging behaviors across the WhatsApp Business Platform before releasing them to all users.

To perform these tests, Meta may temporarily include selected WhatsApp users or businesses in controlled experiments.

If a recipient is part of one of these experiments:

• Message processing may temporarily differ from the standard behavior.

• Delivery responses may vary from what is normally expected.

• Certain WhatsApp features may behave differently during the testing period.

This is a normal part of Meta's platform testing process and is not considered an error.

Why Does This Status Appear?

This status may appear because:

• The recipient has been randomly selected for a Meta-controlled experiment.

• Meta is testing new messaging behaviors or delivery mechanisms.

• The recipient is part of a phased rollout of a new WhatsApp feature.

• Meta is evaluating platform improvements before a wider release.

Since these experiments are managed entirely by Meta, neither Picky Assist nor the business can control or remove this status.

What Should You Do?

In most cases, no action is required.

You can follow these recommendations:

Step 1 – Wait and Retry

If appropriate, wait for some time and try sending the message again later.

Many Meta experiments are temporary and may end automatically.

Step 2 – Monitor the Message Status

Continue monitoring the message status to see whether future messages are delivered successfully.

If the issue occurs only occasionally, it is likely related to Meta's ongoing experiment.

Step 3 – Check Your Account Health

Although this status is unrelated to your account configuration, it is still recommended to verify that:

• Your phone number quality rating is Green (High) or Yellow (Medium).

• Your messaging limits have not been reached.

• There are no active restrictions in your Account Quality section.

Maintaining a healthy account helps ensure optimal message delivery.

Step 4 – Continue Following Best Practices

To maintain good messaging performance:

• Send messages only to customers who have opted in.

• Keep your messages relevant and expected.

• Avoid excessive or repetitive broadcasts.

• Follow WhatsApp Business messaging policies.

What Is Not Affected?

This status does not necessarily mean:

• Your WhatsApp Business Account has been restricted.

• Your phone number has been blocked.

• Your messaging limit has been reached.

• Your phone number quality rating is low.

• Your Picky Assist configuration is incorrect.

• Your message template has been rejected.

These factors are evaluated independently by Meta.

How to Prevent Concerns Related to This experiment Status?

Since this status is controlled by Meta's internal experiments, it cannot be prevented.

However, you can ensure consistent messaging performance by:

• Maintaining a healthy phone number quality rating.

• Monitoring your Account Quality regularly.

• Keeping your messaging practices compliant with WhatsApp policies.

• Sending messages only to customers who have provided consent (opt-in).

Where to Monitor Your Account Health

You can review your WhatsApp account status by navigating to:

Meta Business Suite → WhatsApp Manager

Review the following sections:

• Phone Numbers

• Phone number quality rating

• Messaging limit

• Account Quality

• Policy violations

• Account restrictions

• Enforcement actions

Regular monitoring helps identify unrelated issues that could affect message delivery.

Frequently Asked Questions

Can Picky Assist remove this status?

No. Since the experiment is managed by Meta, Picky Assist cannot remove or override it.

Will my messages be delivered later?

In many cases, yes. As Meta's experiments are temporary, message behavior may return to normal once the experiment concludes. However, the exact duration and outcome are determined by Meta.
