Use Twilio to build an app

We need A program that we can use to send mass custom text messages from both a desktop computer and from mobile devices. We should also be able to receive messages so that it can function like a normal cell phone.

We need to be able to have multiple accounts and each account should be assigned a dedicated long code number.

We want to be able to upload contacts from a phone (via spreadsheet) to an account, and then be able to group those contacts into sub-groups/labels.

Once contacts are sorted into sub-labels, we will be sending bulk texts to each label/group, on a schedule. When these bulk texts go out, we would like to be able to use assignable fields ie: "Hi (first name), I just wanted to see if you will be making it out for (event)."

We need to be able to receive phone calls on these numbers. It's ok if this happens with a simple call forward that is easy to assign, switch forward numbers, and turn off.

A bonus feature would be the ability to automate messages by creating a series of events that trigger bulk messages for a certain group.

For example:

-We create one trigger event for each month of the year.

-By default, each contact (or group) is set to receive the bulk message that occurs 4 months after their last contact. So, if we interact with someone via text in June, that person would then be automatically scheduled to receive the default message that goes out 4 months later in October. But, if we communicate with that person via text in September, they would be automatically moved from the October message and rescheduled for 4 months later in January.
