Dynamic / Weather

Weather in email,
actually useful.

Render location-aware weather at open time, so subscribers see conditions that match their moment, not your send time. Ideal for local newsletters, regional campaigns, and context-driven content.

Why weather works in email

Most campaigns are built once, then age fast. Weather gives each open a local, timely context you can tie to recommendations, reminders, and editorial angles without rebuilding templates.

Strong use cases

  • Local newsletter intros and neighborhood digests
  • City-level retail and restaurant recommendations
  • Travel updates and destination content
  • Event-day messaging with weather context

Customization

Match any brand palette

Accent color and background are URL parameters — swap them per campaign without touching your template.

Dark-mode ready

Transparent PNG — fits any inbox

Set transparent=true and the block drops its background entirely, blending into whatever color your subscriber's inbox or email template uses — including auto-switched dark mode in Apple Mail, Gmail app, and Outlook Mobile. No white box, no hard edges.

Block anatomy

What's in every block

Eight data elements assembled live from NOAA National Weather Service forecast data at the moment of email open.

  1. City name — geocoded from subscriber profile field, ZIP, or IP fallback
  2. Condition icon — NWS official imagery or Material Design icon set
  3. Temperature — average of daily high and low in °F or °C
  4. Condition label — short NWS forecast phrase (e.g. "Partly Sunny")
  5. Feels like — wind-chill or heat-index adjusted apparent temperature
  6. Precipitation chance — umbrella icon + daily probability percentage
  7. Forecast banner — full NWS detail text on the accent-colored bar
  8. Intraday slots — six time checkpoints (6 AM–9 PM) with icon and temp

How location is determined

  • Subscriber profile fields (city, ZIP, region)
  • Geo-based fallback when profile data is missing
  • Static backup location to guarantee render

How delivery works

Create one hosted image URL and place it in your template. At open time, Dynamo resolves weather data and serves the final PNG for that recipient and location context.

FAQ

Practical questions teams ask

Implementation details for editors, designers, and email developers shipping weather-aware campaigns.

How should I use weather in a local newsletter?

Lead with weather context, then connect it to useful local content: what to do today, what to bring, where to go, or what to avoid. Keep the block compact and make the follow-up CTA specific to the current conditions.

How do I add a weather PNG in an ESP template builder?

Use the image block your ESP already provides, paste the hosted weather image URL, and set descriptive alt text. This works in drag-and-drop builders (Mailchimp, Klaviyo, Brevo), hybrid editors, and HTML upload workflows.

What if my team codes emails directly in HTML?

Insert the weather asset as a standard image tag, with explicit width, max-width, and alt text. Use table-safe layout patterns and avoid relying on CSS background images for critical weather information.

What are mobile-responsiveness best practices?

Design for 320px-first readability: strong contrast, concise copy, and a single visual hierarchy. Keep text legible inside the PNG, use predictable spacing, and ensure any related CTA remains thumb-friendly below the weather block.

How often should weather-driven content change?

For daily newsletters, open-time rendering is usually enough. For event-heavy or rapidly changing conditions, pair weather with time-aware messaging and conservative fallback copy so the email still makes sense if data is delayed.

How do I keep weather content accessible?

Treat the image as meaningful content: include alt text with city and summary condition, avoid embedding critical tiny text, and keep nearby copy that conveys the core message even if images are blocked.
