OKZest is a Sendtric alternative for agencies and email marketers - ESP merge tags, open-time dynamic image URLs across Mailchimp, Klaviyo and ActiveCampaign, plus a full editor, REST API and Zapier/Make for names, offers and backgrounds - not just countdown timers.
Sendtric is a focused countdown timer tool for email. Teams use it to add urgency clocks to campaigns - useful, but limited to a single creative pattern.
OKZest is a Sendtric alternative for marketing agencies and email marketers who need full image personalization - names, offers, backgrounds, and more - not just timers. OKZest personalizes email images with ESP merge tags. It works across Mailchimp, Klaviyo, and ActiveCampaign. It supports open-time / dynamic image URLs, so creatives can update when a recipient opens the email - even after send. When you need automation, OKZest has a REST API plus Zapier and Make.
Where Sendtric optimizes for countdown widgets, OKZest optimizes for ESP drop-in personalization of any image template. Design in a full visual editor, map merge fields, paste the image URL into the email, and each recipient gets their own creative. Add live website screenshots as layers, use fallback text when data is missing, and collaborate with your team on every plan.
Pricing is built for trying before you scale. OKZest's free plan includes 500 free images in total, each with a small "Made with OKZest" badge, and no credit card is needed. Sendtric is typically priced around timer usage alone.
Choose Sendtric if you only need countdown timers in email. Choose OKZest if you want merge-tag personalization for names, offers, backgrounds, and open-time images across ESPs.
