Most organizations perform outbound calling typically to customers or prospects to drive business. However, if your phone numbers are labeled as spam, it will adversely affect your contact rates.

People who receive phone calls from numbers marked as “Spam” typically do not engage with the call. This typically results in poor communication with customers and prospects resulting in productivity challenges that lead to lost customers and revenue.

To avoid these challenges, it is important to understand the best practices when it comes to outbound dialing to protect the reputation of your phone numbers and avoid numbers being labeled “Spam”.

Coeo understands how important clean phone numbers are to outbound calling efforts and has helped thousands of organizations with their number reputation by removing spam labels using Number Reputation Management.

By the end of this article, you will understand the challenges with spam labels, best practices for outbound dialing, what Number Reputation Management is, and whether it is beneficial for your organization.

Challenges of spam labels

Spam labels can be improperly placed on your phones for many reasons. Regardless of these reasons, if a spam label appears when calling customers or prospects, chances are your contact rates will not be very high.

Unfortunately, once these labels are placed on their phones, removing them can be difficult. Removing them from your phone solution without the proper expertise can take months and maybe even years, depending on the quantity of numbers that need to have labels removed.

While these spam labels are typically out of your control, if some or all of your numbers are currently clean, you can use the following best practices for outbound dialing to help avoid spam labels in the future.

Best practices for outbound dialing

To avoid spam labels being generated from your phone numbers, it is important to understand the best practices for outbound dialing. These best practices include:

Have respectful and consistent dialing strategies

When manually dialing phone numbers or using an auto-dialer, calling practices should always be respectful and consistent to avoid consumers filing complaints against your organization and getting your numbers labeled as spam.

For example, calling outside of business hours is not only ineffective, it is also frustrating to the customer or prospect and can lead to flagging your numbers as spam.

It is important to plan your dialing habits and be cognizant of time zones so you do not call before or after business hours.

Additionally, it is important to be mindful of the numbers that have already been called and when they have been called to avoid calling the same number multiple times in one day or even one week.

Let your phone numbers rest between max outbound attempts

As mentioned previously, it is important not to over-dial your customers and prospects. A good practice to avoid this challenge is to let phone numbers rest between max attempts.

While this varies across different industries it is important to have a maximum attempt policy that coincides with a resting period so that you are not over-dialing your lead list to avoid call blocking and spam labels.

Avoid dialing from a single phone

Another practice your organization should try when outbound dialing is to avoid dialing your customers and prospects from the same phone. Putting too much call traffic on one phone can result in your number being flagged as spam.

Your dialing patterns may look suspicious if they are all from one number and may get flagged by analytics engines. For this reason, it is best to alternate between different phone numbers when outbound dialing to help avoid spam labels.

Maintain FCC compliance when dialing

The Telephone Consumer Protection Act (TCPA) prohibits telemarketing calls without prior consent from the consumer in response to unsolicited calls being considered an invasion of privacy.

In addition, The National Do Not Call (DNC) Registry is a provision of the TCPA enforcement that allows companies to have their own Do Not Call (DNC) Lists preventing them from receiving unwanted calls.

The DNC List is a list of consumers who have restricted their ability to receive marketing calls unless opting in to receive these calls.

If your organization violates these FCC compliance requirements by ignoring DNC lists, not only is there a good chance that your numbers will be labeled as spam, but your organization will receive fines of $500-$1,500 per DNC call.

What is Phone Number Reputation Management and is it beneficial for your organization?

While these best practices will help you avoid spam labels, there is a chance that your phone calls may occasionally still be labeled as spam.

Using Phone Number Reputation Management by Coeo will help remove spam labels from your phones and ensure the correct reputation and display of your business numbers.

Coeo’s Reputation Management solution helps organizations clean their numbers that have been labeled as spam when making outbound calls and protects phone calls from being blocked by wireless carriers in response to the negative reputation associated with certain phone numbers.

If your organization relies on call centers or other specific roles within your organization to call customers and prospects, it is important to optimize the use of your phones using Reputation Management to experience increased answer rates and better communication with these groups.

If your organization is looking to improve contact rates to increase conversations with prospects and customers, using reputation management may be beneficial.

Additionally, if you are looking to have better insight into the status of your phone numbers to identify which are clean and which have been marked as spam, using reputation management will help you accomplish this.

Using a reputation management solution will also be beneficial if your organization is looking to improve the efficiency and satisfaction of employees who make these outbound calls.
