What do Short Message Service (SMS) marketing and Sam's Club have in common? Both know how to do bulk right.
With SMS marketing, you can reach thousands or millions of your recipients with the right message, on the right channel, at the right time. You can even send in bulk at scale without losing any quality or efficiency.
The same goes for shopping at Sam's Club. You can get everything you want in the quantities you need, saving you time and money.
OK, Sam's Club metaphor aside, bulk SMS marketing (or text messaging) is a powerful way to engage with your audience on their mobile phones. In today’s business world, “58% of consumers say texting is the best way for businesses to reach them quickly,” as opposed to 21% who prefer phone calls and 21% who prefer email communications.

Webhooks are a way to be notified by an external service when an event has occurred. Instead of you sending an HTTP request to that service, the service sends an HTTP request to your public web service. This way, you can respond to the event in real-time as it happens. Webhooks are also a common way to integrate with Twilio's products. For example, when your Twilio phone number receives a text message or phone call, Twilio sends an HTTP request to your service with the details. Your service then responds with instructions that indicate how Twilio should respond to the event. Here's a diagram of what this exchange looks like:
One common challenge with webhooks is that they can only call web services that are publicly available on the internet, but when you are initially developing software, you are typically doing so on your own local machine, which by default …

There may be instances when you’d like to send a text message, but the timing isn’t quite right. Maybe it’s too early, a bit late in the evening, or it would make more sense to send something a few days from now. But waiting to send a text means you risk forgetting about it completely. So how do you write a text and send it later? You can schedule a text message or use a workaround.
The method available to you will vary depending on your mobile device. Below, we lay out a few ways to get the job done (or get close to it). Some Android users, for example, have a scheduling feature built into their default text message app. iPhone users, however, don’t have that option. And if you’re interested in sending scheduled messages to your customers, we include a section that explains the most efficient way to …

The steps to find this data but will vary depending on whether you have an Android or iOS device. Most handset manufacturers use the Android phone operating system, including Google, Samsung and Motorola. While Apple phones run exclusively on iOS.
Everyone has a preference when it comes to which phone to buy. But as of June 2020, Statcounter found that Android had 74% of …

When it comes to blogging software, you're not starved for choice. However, despite this choice and how feature-rich modern blogging software is, are the available options necessarily the right choice?
Sure, software such as WordPress, Ghost, Gatsby, and Wix are very feature-rich — and their UIs are often very smooth. But do you want the hassle of installing, configuring, and securing them on top of writing your blog content? What's more, can you justify the budget that some blogging software requires?
Maybe, all you want to do is to write your site's content using your preferred editor, using a simple format designed for writing for the web, Markdown, rather than through a user interface.
If that’s the case, then in this tutorial, I’m going to show you how to create a blog that draws its content from Markdown files. The blog uses the Slim Framework (version 4), the Standard PHP …

While AWS components are generally resilient, when you run at the scale of Twilio, it becomes necessary to fine-tune things to achieve the highest level of quality and availability.
In this post, we’ll examine how to improve the Elastic Load Balancers (ELBs) to increase their fault tolerance. Using custom health checks and multivalued DNS records, we will be able to obtain fine-grained metrics on the availability of each of the ELB constituent nodes. With these metrics, we can adjust the self-healing behavior of the ELB with any criteria we consider for our purposes.
Requirements
In order to implement the fault-tolerant ELB solution, you need an AWS account with permissions for creating:
- Route53 hosted zones and records
- DNS Health Checks
- Elastic Load Balancers
- CloudWatch Alerts
About the Elastic Load Balancer (ELB) internals
In order to understand the solution, it’s necessary to know a little bit about the internal structure of …
