Blocking callers for solicitation

An advertisement over the telephone is known as a telephone solicitation. The National Do Not Call Registry gives you a choice about whether to receive telemarketing calls or block callers for solicitation.

Overview of the National Do Not Call Registry

Companies can call you if you’ve recently done business with them, or if you’ve given them written permission to call. But if you ask them not to call you, they have to stop. Be sure to write down the date you asked them to stop.

The National Do Not Call Registry was created to stop unwanted sales calls. It’s free to register your home or cell phone number.

The Registry is a list that tells telemarketers what numbers not to call.

Read about blocking unwanted calls to find out what to do about them. If you answer one of these calls, hang up and report the call to the FTC.

Blocking callers for solicitation

  • In aNinja, you can block a phone number and forbid it from calling you.
  • To block the solicitation callers, you can register your home or mobile phone for free.
  • Registrations on the National Do Not Call Registry do not expire. So, if you have previously registered your number, there is no need to register again.
  • After you register, other types of organizations may still call you, such as charities, political groups, debt collectors, and surveys. To learn more, read the FAQs.
  • If you’ve already added your phone number to the Do Not Call Registry and are still getting a lot of unwanted calls, odds are the calls are from scammers.
  • If you received an unwanted call after your number was on the National Registry for 31 days, report it to the FTC.

Keeping a clean database

Bad data infiltrates every database in form of duplicate contacts, un-standardized lead data, and junk records. While you can’t always keep bad data from coming in, you can clean it up when it’s there.

In order to keep a clean database, you can sanitize your contact file before you import it, and perform a clean-up routine to the existing data.

Importing a correct data

Before you import contacts in a CSV/Excel file, check the following tips:

  • Provide correct email addresses to ensure the deliverability of your emails.
  • Provide correct phone numbers to ensure the deliverability of your texts and campaigns.
  • If possible, assign the mobile number to the primary phone number.
  • Ensure the uniformity of custom fields: don’t create multiple custom fields for identical data. This will lead to confusion over the correct custom field to keep updated, and over the Smartlists results.
    • e.g. on a first data import, custom field “Source”; on a second data import, custom field “Created through”, on a third “Origin”, on a fourth “From”. This creates 4 custom fields for one identical data.
  • Set the Global Setting rule: Do not add new Leads via API if Lead with similar email already exists (avoids duplicates)

Cleaning up the existing data

However, the bad data can still be cleaned up when it’s already there.

  • Remove duplicates
    • Go to Settings > Data Clean up
    • Choose the merging method (by email or by phone)
    • Repeat this task every now and then, depending on the volume of the incoming leads.
  • Prune inactive and junk contacts
    • Contacts with no emails and/or phone numbers are of no use in your database.
    • Leads who asked to stop receiving from you can crowd your database and preferably be deleted.

Keeping a clean database reserves more space for the correct data.

Things to consider before Bulk Texting

Bulk texting is an aNinja great tool that you use to nurture your leads and keep them updated with your latest campaigns, and offers, and send them reminders. Here are a few things to consider before bulk texting.

Things to consider before bulk texting

Here are some things you would want to consider/check before sending out your text blast.

  • Phone number to send out the texts

To be able to send texts, you want to have a phone number saved in your aNinja account. Either you buy a new phone number from aNinja or you port your own.

  • Leads phone numbers

If possible, provide a mobile number in the lead’s primary contact to ensure the delivery of your message.

  • Text segmentation

When crafting a text template, you want to count the characters you’re adding to this text. A text is composed of 160 characters which is considered one segment. If your text exceeds 160 characters, it will be delivered to the recipients anyhow, but you will be overcharged for all the extra segments by your phone carrier.

  • Text limit per bulk/per user

According to your Billing plan (only for Advanced and Pro plans), each user can send 2000 SMS per bulk.

If you wish to increase your SMS limit, either:

1- Reach support at and they will bump it up for you, with a one-time charge of 15$ for every additional 1000 SMS per user.

2- Enable the auto-recharge for Billing, that automatically recharges your add-ons once your plan included add-ons are hit.

3- Or, limit your bulk texts to 2000 SMS per bulk by segmenting the contacts in the CSV file before you import it.

SPAM risk caller ID

SPAM risk caller ID

Your customers might see calls from your number displayed as “SPAM likely” or “SPAM risk” or “SCAM likely” on their caller ID. While each phone carrier keeps a list of numbers they determine to be spam risks based on the history of the number; scam ID technologies might incorrectly mark your number.

What causes the SCAM/SPAM designation

Here are the most obvious reasons for designation:

  1. The volume of Outbound Calls Per Day Per Number
  2. Or, someone flagged a call from your number in that carrier’s app as spam
  3. Or, it could be your system didn’t correctly set the Outbound Caller ID number

What’s the back story

In response to the growing number of scam calls to mobile phones; many carriers have created tools to identify and block scam calls. Unfortunately, these tools aren’t perfect. And sometimes businesses may have their numbers incorrectly marked by scam ID technology, particularly when calling cell numbers.

Each carrier has a feature or app. And it is automatically enabled on mobile devices. So, when someone calls one of these devices, the carrier checks the number against its database of reported scam numbers. If the source matches a reported scam number, directly, the person being called sees a message that says “Scam Likely” alongside standard caller ID. 

However, the Scam Likely Caller ID features will sometimes mark legitimate calls incorrectly; because some people may report your number without answering the phone. If this happens enough, as a result, your number will be marked Scam Likely.

To reduce the chances that a scam ID flag your number, you want to register your number at Free Caller Registry.

Registering your number at Free Caller Registry

You can register your number at Free Caller Registry by following these links:

This helps register/white-list your numbers with the major carriers. It also reduces the chances of them being flagged. Moreover, all numbers and information provided will be shared with all Carrier Spam Monitoring Partners.

Request to remove your number from the SPAM/SCAM designation

You can use the links or email addresses below to register legitimate numbers and also address any incorrect labeling or call blocking with other carriers:
