    Receive SMS Alerts for Email Opens and Clicks with Twilio SendGrid and Node.js SMS alerts for email opens and clicks header image (2)

    When it comes to messaging applications, read receipts are a common feature that allow you to know if your recipient has read your message. For email applications, this feature is very uncommon; however, when sending marketing and especially important emails, it's sometimes vital to know and keep track of whether your recipients have opened and read your email.

    When using Twilio SendGrid, keeping track of email engagement is seamless through Event Webhooks. Event Webhooks not only track the delivery status of your emails but also engagement events such as if an email has been opened or a link within an email has been clicked. Pairing open and click tracking for emails with Twilio’s Programmable SMS API will ensure you’re up to date on the status of your important emails.

    In this tutorial you’ll learn how to track and send SMS alerts for open and click events for your …

    SMS Notifications On Pageviews with Segment and JavaScript Copy of D03 Blog Image Round (2).png

    Twilio acquired Segment last year to help developers unify customer data across every customer touchpoint. I held off on using Segment for a while because I thought Segment was only for businesses, but I learned recently that I, an indie developer, have a use case for it. Read on to learn how to use Segment and Twilio Serverless to send SMS notifications when someone visits your website.

    How to Play Video Files in a Twilio Video Call How to Play Video Files in a Twilio Video Call

    A common need in video calling applications is to allow a user to play a media file for the other participants in the call. This can enable, for example, a teacher or doctor to share a recording with the call attendees.

    In this article I will show you how a participant in a Twilio Video call can share video and audio content in formats such as mp4 or webm.

    The MediaStream API

    The JavaScript version of the Twilio Video SDK uses existing APIs in the browser to obtain access to the camera and microphone. More specifically, it uses the MediaDevices.getUserMedia() function to access MediaStream objects for these devices, which expose the raw video and audio tracks that are then published to the video call.

    But the MediaStream APIs cover much more than webcams and microphones and can be used to obtain MediaStream objects from other sources. For example, the …

    Twilio SendGridとNode.jsを使用してメール問い合わせフォームを構築 How to build an email contact form with SendGrid and Node JP

    この記事はPhil Nashこちらで公開した記事(英語)を日本語化したものです。


    本稿では、Twilio SendGridベースの開発プロジェクトの一例として、ウェブサイト上で問い合わせフォームを構築し、メールアドレスを公開することなく問い合わせのメールを受け取れるようにする方法を説明します。

    プロジェクトはTwilio Functionsも使って構築しますが、本稿でご紹介するコードはあらゆるNode.js環境での使用に対応しています。


    ユーザーがお問合せフォームを送信した際は、お問合せフォームを入力した人のメールアドレスを送信元とするメールがウェブサイト運営者に送信されることがよくあります。しかし、メール送信に関する信頼性を維持するため、Twilio SendGridは単一送信元として検証されたアドレス、または認証済みのドメインからの送信しか許可しません。

    そのため、提供されたメールアドレスをfromアドレスとして使用する代わりに、reply-toアドレスに設定できます。この方法であれば、Twilio SendGridは認証済みメールアドレスからメールを送信する一方で、受信 …

    How to Collect Times and Dates in Voice Calls or SMS using JavaScript How to Collect Times and Dates in Voice Calls or SMS using JavaScript

    Twilio offers a wide variety of channels you can use to connect with your customers, for example, through an SMS or Phone Call. One of the ways you can use these channels is to collect data from your customers. Depending on the type of data, this can be a complex undertaking. Collecting individual words or numbers is usually pretty straightforward. However, when asking customers to share specific Times and Dates, this can be far more complex. A typical use-case might be the scheduling of an appointment. This is especially true when allowing customers to communicate in free form (for example, “I would like an appointment next Tuesday at 3 pm”).

    In this blog, I will show you how you can extract Times and Dates during a phone call using JavaScript and serverless Twilio Functions without the need for any 3rd party integrations.


    To build this solution, you will …

    Twilio's Unofficial Vote for the Eurovision Song Contest Twilio's Unofficial Vote for the Eurovision Song Contest

    Eurovision is near and while you can't officially vote just yet, we thought we'd allow the public to vote already - and not just for this year but for ALL Eurovision's that have happened since the beginning of Eurovision. That includes 2020 - the year Eurovision was cancelled.

    How do I vote?

    Text '2022' to one of the following numbers to get the list of all the 2022 participants and their youtube videos. Once you have picked a winner, text “2022 Country” to the same number (e.g. 2022 Germany).

    Netherlands: +3197010253872

    UK: +44 7401 199687

    Sweden: +46 70 192 18 32

    United States: +1 (267) 713-3577

    What about the other years... Could we maybe vote for those too?

    You can text any year from 1956 to 2022 to any of the above numbers and then vote for your favourite song.

    How do I see the results?

    You can see the …

    Synchronized State Variables for React using Twilio Sync Synchronized State Variables for React using Twilio Sync

    State variables are one of the most important building blocks in front end applications developed with the React library. When a state variable is updated, React automatically re-renders any application components that depend on it, ensuring that the application always displays updated information to the user.

    The automatic state update mechanisms in React are fantastic, but they are limited to a single instance of the application. Sometimes, however, an application needs state variables that are automatically synchronized across all running instances of the application. In this tutorial you are going to learn how to create a custom React hook that implements synchronized state variables using Twilio Sync as a cloud storage back end.
