# Twilio Integration

> **Twilio integration** enables users to import their Twilio phone numbers into thinkrr seamlessly, allowing full functionality for inbound and outbound calling.

## Overview

Whether importing numbers during setup or adding them later, thinkrr ensures flexibility without limitations on usage. While Twilio phone numbers offer great compatibility, users should be mindful of associated costs and best practices for maintaining clean, high-quality numbers.

## Details

We’ve made it super easy to import Twilio phone numbers into the thinkrr Voice AI platform. Every new account includes **one free phone number**, which can be claimed at any time.

Additional phone numbers can be purchased for **\$1.90 per month each**, billed as a recurring subscription. All numbers available within thinkrr — including those purchased directly through the platform — are **Twilio-based**, and users can buy up to **50 numbers at a time** in a single batch.

## Twilio Number Quality & Cleanliness

Although Twilio numbers are imported from an external provider, it's still important to ensure that the phone numbers you bring into thinkrr are clean and not flagged as spam. Flagged numbers can negatively impact outbound campaigns, connection rates, and overall deliverability.

### Recommended Pre-Import Checks

Before importing Twilio numbers into thinkrr, run them through these third-party lookup tools:

* [Robokiller Lookup](https://lookup.robokiller.com/)
* [Should I Answer?](http://www.shouldianswer.com/)
* [Nomorobo Lookup](https://www.nomorobo.com/lookup)
* Search the number on Google using quotes (e.g., "614-758-2315") to check for public spam complaints.

> ⚠️ **Important:**\
> Once a number is flagged as spam, it is extremely difficult (often impossible) to remove it from global spam lists. Regularly auditing your numbers helps maintain deliverability.
