Quick summary
Resend is an email API built for developers. It sends transactional messages such as receipts, password resets, and notifications from your application code. It also offers a way to manage contacts and send broadcasts, and its developer experience is one of its strongest points.
Ternloop is a newsletter and campaign tool. You write a campaign in the editor, import contacts, group them, and send or schedule the message from a dashboard. It focuses on campaigns you write in the editor. Its pricing follows the number of emails you send each month.
If your team is writing code to send transactional email from an app, Resend is designed for that job. If you want to write newsletters and send campaigns from a dashboard, Ternloop is the simpler fit.

At 50,000 emails a month, Ternloop's Pro 50,000 tier costs $25 a month, with a 30,000 contact limit. Resend's Pro plan lists $20 a month for 50,000 emails in the comparison we reviewed. The two prices are close at this volume, but the numbers are not measuring the same thing. Resend's plan is priced for API sends, while Ternloop's plan includes contact storage and campaign tools.
Choose the plan that matches your work. If your app sends a few thousand receipts and alerts each month, the Resend API may be the right tool. If you send a newsletter to a list of subscribers, Ternloop's contact limits and campaign tools matter more than API volume.

Resend is built for developers. It gives you a clean API, SDKs, and templates written in code. Teams that want password resets and order receipts to come from the same system will find it a good fit. Ternloop is built for newsletters and campaigns, so transactional sends are better handled by a developer-focused tool.
Ternloop is built for people who write campaigns. The rich editor and block editor let you compose a newsletter without code, and you can schedule it, group your contacts, and read open and click data in the dashboard. The free plan includes 1,000 emails and 500 contacts each month.
When to choose Ternloop
- You send newsletters, updates, or campaigns to a list from a dashboard.
- You do not want to write code to compose or send email.
- You want contact groups, CSV import, and scheduling on one plan.
- You want a plan priced by monthly volume, with clear contact limits.
When to choose Resend
- Your application sends transactional email such as receipts and alerts.
- Your developers want an API, SDKs, and templates in code.
- You need sends triggered by application logic.
- You are comfortable building your own list tools or using Resend's audience features.
Many teams use both. A product can send receipts through an API and send the monthly newsletter from a campaign tool. The choice depends on which job you are hiring the tool for.
Start with Ternloop
You can start with 1,000 emails and 500 contacts a month on the free plan. Import a small list, send a test campaign, and check the open and click data. When your list grows, the Pro tiers scale by volume. Full details are on the pricing page.
Questions to ask before you switch
Start with your team. Resend is built for developers who connect email to their code. Its dashboard is designed for engineers, which makes it a strong fit for application email. Ternloop is built for writers and marketers who want to write, schedule, and track campaigns without code.
Next, compare costs at your volume. The comparison we reviewed lists Resend's free plan at 3,000 emails a month, its Pro plan at $20 a month for 50,000 emails, and its Scale plan at $90 a month for 100,000 emails. Ternloop's free plan includes 1,000 emails a month, its 50,000 email tier is $25 a month, and its 100,000 email tier is $50 a month. Check Resend's current pricing before you decide.
Then check the features you need. If you need a developer API for application email, Resend is the stronger fit. If you need a dashboard that a teammate who does not code can use to write a newsletter, Ternloop is designed for that work.
Finally, plan the move. Export your contacts, import the CSV into Ternloop on a Pro plan, and send a test campaign to a small group. Confirm that unsubscribes and bounces update your list before the full send.
