Benefits of Using Phone Validator

Phone validators are highly useful and versatile tools with a variety of benefits for any business. Byteplant's Phone Validator offers the following advantages:

1. Save Time and Money

Calling non-existent, or worse, outdated phone numbers requires your team to spend extra time apologizing, re-dialing the number, and changing their calling schedule - this is especially important if your CRM Phone Lists contain thousands or hundreds of thousands of contacts. By running your phone number lists through the phone validation tool, you can save your sales and marketing team a significant amount of time.

Besides avoiding invalid numbers, you get an opportunity to contact your customers through other channels and verify their phone numbers. Otherwise, you could lose contact with an existing client due to an unintentional data error.

2. Improve Your Reputation

Calling wrong numbers can take a toll on your company's reputation. As people add your phone number to their blacklist, your reputation suffers. To make sure your company’s reputation stays in top shape, it's imperative to check the phone list regularly.

Consumers tend to change phone numbers. When that happens they rarely notify all the companies they work with. By making sure you are calling the right number, you don't just confirm the point of contact with the customer but also confirm their interest in your offer.

3. Optimize Your Marketing Campaigns

A phone list is often one of the most powerful tools in the marketer's arsenal - especially for SMS/mobile marketing campaigns. The ability to contact potential and existing clients over the phone or by mobile messaging/SMS drives your marketing campaigns forward. However, without a clean list, the entire effort takes more time, demands more attention, and requires more expenses.

By running your phone lists through the validation tool regularly, you can make sure you are contacting and messaging the right people whenever it's necessary. This can help move them down the sales funnel and close more deals far more efficiently.

4. Streamline Retention

Retention is a highly important marketing tactic. By using existing phone numbers, you can inspire brand loyalty in your clients and re-engage them whenever they seem to lose interest in your offer. However, invalid or outdated phone numbers nullify your efforts and put you in danger of losing high-paying clients.

A phone validator can notify you whenever there is an issue with a phone number so you can use other means of communication to keep in touch with the customer.

5. Improve Campaign Analysis

The analysis of your sales and marketing campaigns directly depends on how many phone calls you make. However, if a certain percentage of your phone calls goes out to the wrong numbers, you can get a wrong idea of how well your strategy is working.

By obtaining a clean phone list, you can be sure that each call you make goes out to the right recipient, thus optimizing the performance of your campaigns.

6. Collect Phone Numbers right at the Point of Contact

With Byteplant's Phone Validator API, you can validate in real-time, that a phone number is valid right at the point of entry - dramatically improving customer phone number data quality in your CRM and ERP systems.
