Stop paying hundreds a month to send emails.
Newsletters, contact lists, drag-and-drop design — included in Diviner One. Unlimited subscribers. You connect a free Resend account and pay pennies for what you actually send. No per-contact tax.
The contact-count tax
Most email tools charge by the size of your list, not by how many emails you actually send. A 10,000-contact list you email once a month costs the same as one you blast daily. You're paying for the right to have contacts on file — and the price climbs every time your business grows.
Unlimited subscribers. Pay for sends, not seats.
Store 500 contacts or 500,000 — the price doesn't change. Resend prices the way email economics actually work: a few pennies per thousand emails sent. We give you the campaign builder, contact management, and tracking on top. You don't pay Diviner extra for any of it. You don't pay Resend until you outgrow the free tier.

Free at 2,500 contacts
Sending a monthly newsletter to a few thousand customers? You'll likely pay $0 for sending. Most competitors charge $45+/mo at the same list size.
$1,000+ saved per year at 10,000
At a 10,000-contact list with weekly sends, you save $90 to $155 every month versus the major email tools. That's $1,000–$1,900 a year, every year.
Prices are approximate, based on each provider's published marketing plan for the listed contact count. Feature sets differ — some competitors include automation and template libraries we don't yet match. See the FAQ below for what's in and what's not.

Frequently asked questions
- No. Store as many contacts in Diviner as you want — 500 or 500,000, the price doesn't change. You only pay (via Resend) for emails you actually send. That's the opposite of how Mailchimp, Constant Contact, and Klaviyo work, where your bill climbs every time your list grows.
- Because the markup other email tools charge mostly pays for their delivery infrastructure — and Resend already runs better infrastructure than most of them. Instead of bundling delivery cost into a monthly subscription, we let you pay Resend directly at cost (often $0). You get a real, modern sending platform, and we focus on the campaign and contact tools on top of it.
- Yes. Resend is built by the team behind React Email and is the email provider used by companies like Vercel, Linear, and Cal.com. It handles SPF, DKIM, and DMARC setup automatically and has strong deliverability into Gmail and Outlook. It's not a discount option — it's just priced fairly.
- Resend's free tier covers 3,000 emails per month. A monthly newsletter to a 2,500-contact list fits free. Above that, Resend Pro is $20/mo for 50,000 emails — enough for a weekly newsletter to a 10,000-contact list. Compare that to Mailchimp at the same volume (~$110/mo) and the math is hard to argue with.
- Yes. Export your contacts to CSV from your existing tool and upload them in Diviner. Tags and unsubscribe status come along. You can run both systems in parallel while you test deliverability if you want to be careful about the switch.
- Today, Diviner's email marketing is built for newsletters, campaigns, and broadcasts to segments. Multi-step drip automations aren't part of the current release — if that's central to how you market, this isn't the right tool yet. We'd rather tell you that up front than charge you a premium and disappoint you.
