Postmark is a transactional email service known for fast delivery and high inbox placement. It supports transactional and broadcast emails. Tickvio works in both.
For developers sending through Postmark's API or SMTP, the Tickvio image tag goes directly into the HTML body or template.
Tickvio works the same way with other email platforms. See how it integrates with SendGrid, Mailjet, Mailgun, and Amazon SES. Ready to get started? Set up your first timer or see a live demo.
Add a timer to Postmark in 3 steps
- 1
Generate Your Timer in Tickvio's Dashboard
Open Tickvio and create a new countdown timer. Set the deadline date, time, and timezone. Choose a timer design — Filled Boxes, Flip Clock, or Pill — and customise colours to match your email layout. For broadcast emails with a universal deadline, select fixed-date. For transactional or per-user emails triggered at different times, select evergreen. Copy the generated embed code.

Add the Image Tag in Your Postmark Template
For Postmark Templates: open the template in the editor and paste the Tickvio image tag in the HTML body where you want the timer — above or below the CTA is most effective. For API sends: include the image tag in the HtmlBody parameter of your API call. For SMTP relay: add the tag directly to your HTML email template in your application code. Send a test to verify the timer renders live.

Send — The Timer Renders Live
Trigger the send through your preferred method — API, SMTP, or the Postmark dashboard. Every recipient who opens sees the live countdown. The timer image loads from Tickvio's CDN after Postmark delivers the email, so there's zero impact on Postmark's delivery speed or inbox placement rates. For transactional emails, the timer renders on every open regardless of how many times the recipient re-opens.
What you get with Postmark
Works in Both Transactional and Broadcast Emails
Tickvio works in both of Postmark's email streams. Transactional emails — order confirmations, shipping notifications, password resets, account alerts — all support the timer embed. Broadcast emails — newsletters, promotions, announcements — work identically. One embed approach covers both streams, so you don't need separate timer configurations for different email types.
No API Integration Between Tickvio and Postmark
No API key exchange between Tickvio and Postmark, no webhook configuration, no server-level settings changes. The timer is a hosted image URL that Postmark renders like any other image in your HTML template. This means zero impact on your Postmark account's sending reputation, no additional API calls, and no dependencies between the two services.
Developer-Friendly: Standard HTML
For developers already building with Postmark, adding a Tickvio timer requires zero additional dependencies. No SDK, no library, no Tickvio API calls from your application code. It's a single HTML image tag added to your existing template. If you can include an image in your Postmark email, you can use Tickvio — the integration complexity is effectively zero.
What to build with Postmark
Order Confirmation with Cross-Sell Timer
Add a Tickvio evergreen timer to order confirmation emails sent through Postmark's transactional stream. Include a 24-hour limited cross-sell offer alongside the timer — for example, a discount on a related product or free shipping on a follow-up order. The timer creates a visual deadline that turns a standard transactional receipt into a conversion opportunity.
Password Reset with Security Expiry Visual
Add a Tickvio evergreen timer to password reset emails showing the reset link's expiry time visually. Most reset links expire in 1-4 hours, but users often don't act immediately. The countdown timer makes the expiry tangible — users see the time ticking down rather than reading small-print text about link validity, which drives faster action and fewer support tickets.
Broadcast Email with Limited-Time Offer
Send a Postmark broadcast email with a Tickvio fixed-date timer for a limited-time promotion. The timer counts down to when the offer ends, creating visual urgency for all recipients. For Postmark users who primarily send transactional email but occasionally run promotional broadcasts, the timer adds a conversion-focused element that transactional-style templates typically lack.
Supported features: Transactional emails (API), Broadcast emails, Postmark Templates, SMTP relay.
Rendering: Animated GIF in Gmail, Apple Mail, Yahoo, and mobile clients. Static fallback in Outlook desktop.
