Twilio integration for contact form 7 is the best thing that ever happened to WordPress users. No one likes to be rejected when sending out mass messages to their contacts, but this functionality addresses this issue perfectly. Twilio provides a great platform for sending SMS from your WordPress blog or website. All you have to do is install the Twilio SMS plugin for WordPress and you can instantly start sending SMS from any of your WordPress site’s pages.
One thing to note first though, that you should always make sure your Twilio account is active before attempting to use this plugin. Twilio requires a toll free phone number in order to send SMS and there must be no block in the incoming call queue. This is very different from the regular SMS that you send from a cellphone, as there are no such queues in a cellphone. If you have no phone numbers available, then you will need to use Twilio phone number lookup or Twilio lookup. Both of these plugins are easy to use and will work just fine.
Once installed, you will need to configure your Twilio account to receive calls through this plugin. Twilio does not support incoming calls from non-local numbers, so if you were expecting to be able to send SMS from a contact form on your blog, you will find this feature does not work. Fortunately, Twilio supports all major numbers of countries worldwide, so you should be fine if you want to send SMS from your contact form in another country. To test this out, test out your Twilio phone number lookup plugin on a landline number and compare the number to Twilio’s call queue.
It is easy to test this plugin with numbers that you already have numbers associated with. To do this, go to Twilio’s website, and follow the instructions to download and activate the plugin. Once activated, plug in your numbers into the provided fields on the form, and send a test message. If there is a successful connection, a Twilio number will appear in the message sent back to you. If there is a failed connection, a “400 Bad Request” message will appear, and you may have to re-download the plugin.
Once installed, you can configure Twilio to send customized messages based on information that you provide on your contact form. For example, if you have a blog, you can configure Twilio to deliver a web-page as soon as a new visitor enters the address into the web form. In this case, the page would display whatever you had in the Twilio database, rather than a generic “contact us” page.
This plugin is quite versatile, but there are some limitations. The first limitation is that Twilio cannot be used to send SMS (Short Message Service) in response to a Web page. However, there are a number of third-party plugins that make it possible to use Twilio to send SMS via URLs. This allows you to send an SMS from your computer to a specific phone number, even if you don’t have Twilio integrated into your web site. There are even third-party applications that allow you to access your Twilio account from a browser window rather than from a desktop. This is obviously more convenient.
