Quiet hours: send SMS messages only during each recipient's sending hours
Customer.io adds quiet hours for SMS and MMS, holding messages until each recipient’s local sending window begins. Workspace-wide settings include US-based defaults, custom hours by region, and exemptions for transactional and selected messages.
Quiet hours hold your SMS messages until the recipient's local sending hours begin, helping you respect your recipients' time and local laws. You turn them on once for your workspace, and they apply to SMS/MMS messages in your automations, broadcasts, and one-time sends.
Customer.io works out each recipient’s region and local time from their phone number. If a text comes due outside that region’s sending hours, Customer.io holds it and sends it when the hours begin. You start with default hours based on US federal and state rules, and you can change the hours or add your own for any country or US state.
Transactional messages are exempt from quiet hours. You can also exempt event-triggered automations, a single one-time send, or an individual message in your workflow—situations where a recipient might want or expect a message outside of their sending hours. You’re responsible for making sure your sending hours follow the laws that apply to your messages.

Background patterns
Buttondown adds customizable website background patterns to its Modern theme, with eight designs and options for pattern and background colors, including separate colors for dark mode.
Add chevrons, polka dots, graph paper, and more to the background of your website.
If you're a web developer of a certain age, the URL subtlepatterns.com might hold a special place in your heart. It certainly does in mine.
Getting to mess around with its hundreds of chevrons and spirals and halfway open doors to fun but ultimately disastrous aesthetic choices wasn't just a way for my younger self to explore and mature a sense of design. It taught me a lot about the web and graphics in its own meager way. It's how I learned about tiling and SVG backgrounds and a whole host of other things aside.
It also showed me the value of texture in a literal sense. Aesthetic preferences are cyclical, but being able to pepper in a few skeuomorphic affordances here and there forced me to think hard about what the intent of some of my designs were, what elements I wanted to spotlight versus what ones I wanted to recede, and so on.
Mostly though, they were and are just fun and neat, which is the overriding reason why we have brought them, or at least a very small subset, to Buttondown. You can now add patterns to the background of your website. Go ahead, give it a spin:
You'll find it under Background in your Web settings if you're using the Modern theme. Pick one of eight patterns, then a background color and a pattern color. If you've turned on dark mode, you can set separate colors for it too.
Extra big thanks to Jim Raptis of Magic Pattern for inspiring many of these!
Enjoy yourself responsibly.
