If "transactional email" is genuinely the whole requirement — no marketing campaigns, no contact lists, no A/B testing — Notify is the better fit. SendGrid is built as a combined Email API and Marketing Campaigns platform, and its pricing, dashboard, and feature set reflect that. Notify is built around exactly one job: send transactional email, verify your domain, log what happened, and notify your app via webhook — nothing else, at a flat, published price.
Here's the reasoning, not just the verdict.
Why "Notify vs SendGrid" Depends Entirely on What You Mean by "Need"
SendGrid is one of the oldest and most widely used names in this space, and for good reason — it handles enormous volume and is a defensible choice if you're running both marketing campaigns and transactional sends. But that breadth is also the catch for a narrower use case. SendGrid's Email API product (free trial, then Essentials, Pro, Premier) is a different, separately billed product from its Marketing Campaigns product (Free, Basic, Advanced) — so a team that wants both ends up paying for two subscriptions on two different pricing tracks.
If your application's mail is entirely triggered by user actions — password resets, verification links, receipts, order confirmations, security alerts — you're not the audience for drag-and-drop builders, contact segmentation, or campaign analytics. The real question isn't "which platform has more," it's which one gets a transactional email delivered, logged, and reported on, at the lowest cost and lowest setup overhead.
What "Only Transactional Email" Actually Requires
Strip it down and the requirement list is short:
- An API that sends one email to one recipient, triggered by your backend.
- A verified sending domain (SPF/DKIM, ideally DMARC) so mail authenticates and lands from your own address.
- Delivery logs — did it send, deliver, bounce, get opened or clicked.
- Webhooks, so your app can react to those events instead of polling.
That's it. No list management, no unsubscribe workflows, no campaign scheduling.
How Notify Handles This
Notify's entire product maps onto that list and stops there. There's one endpoint to send, domain verification for SPF/DKIM/DMARC, delivery logs, and webhooks on paid plans — with no template studio, no marketing tooling, and no separate product to buy if you decide you need both later, because there isn't a "later" product to buy.
const response = await fetch('https://notify.cx/api/email/send', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'x-api-key': process.env.NOTIFY_API_KEY
},
body: JSON.stringify({
to: 'user@example.com',
from: 'noreply@your-verified-domain.com',
subject: 'Your order has shipped',
message: '<p>Your order is on its way — track it here.</p>'
})
});
That's the complete sending surface. You write the HTML (or have your AI write it); Notify delivers it and reports back through logs and webhooks.
How SendGrid Handles the Same Task
SendGrid's Email API can absolutely do this — it's a mature, high-volume-capable REST API with event webhooks and its own logging (branded as Email Activity). The difference is what surrounds it. Notify has put together a fuller side-by-side on this exact comparison if you want the complete breakdown; the short version:
- SendGrid's paid Email API tiers (Essentials, Pro) start at roughly $19.95/month for around 50,000 emails, scaling to $89.95/month on Pro — both meaningfully above Notify's pricing at comparable volume.
- Full delivery/event history beyond a few days is often gated behind an add-on on the lower tier.
- If your team ever wants SendGrid's Marketing Campaigns tools too, that's billed as a separate subscription on its own contact-based pricing — not included in the Email API price.
- The dashboard and docs are built to cover both a transactional developer audience and a marketing/campaigns audience, which means more surface area to navigate for a team that only ever touches one endpoint.
None of that makes SendGrid a bad product — it's a reasonable choice if you're already sending marketing campaigns and want transactional mail under the same account, or if you need SendGrid's dedicated-IP and enterprise deliverability tooling at real scale. For a team that only needs to send transactional email, though, it brings along more than the job calls for.
Notify vs SendGrid, Side by Side
| Notify | SendGrid (Email API) | |
|---|---|---|
| Free tier | 1,000 emails/mo, 1 domain, 48-hour logs | ~100 emails/day trial-style free tier |
| Cheapest paid plan | $10/mo (Pro) — 10,000 emails, 3 domains, permanent logs, 3 webhooks | ~$19.95/mo (Essentials) — ~50,000 emails |
| Mid tier | $50/mo (Scale) — 100,000 emails, everything in Pro (permanent logs included), 10 domains, 10 webhooks | ~$89.95/mo (Pro) — higher volume, dedicated IP |
| Marketing tools | None — not part of the product | Separate product (Marketing Campaigns), billed separately |
| Email content | You (or your AI) write the HTML | Supports raw HTML plus SendGrid's own design tools |
| Webhooks | Included on Pro and Scale | Included on Email API plans |
| Best suited for | Apps that only send transactional email and want the minimum infrastructure to do it | Teams that want transactional + marketing email under one vendor, or need enterprise-scale deliverability tooling |
At the entry paid tier, Notify's $10/month is about half of SendGrid's Essentials price — and unlike SendGrid, that price doesn't leave a second, separately billed product waiting on the other side if your needs ever touch marketing email.
Where SendGrid Still Makes Sense
To be fair to the other side: if you're a larger team that genuinely runs both marketing and transactional email and wants one vendor relationship, or you need dedicated IPs, subuser management, and enterprise deliverability support at very high volume, SendGrid's Pro/Premier tiers are built for exactly that. That's a different requirement than "I only need transactional email," which is the question here.
So, Which Should You Use?
If your app's email is entirely transactional — triggered by user actions, not campaigns — Notify is the more focused and lower-cost answer: one endpoint, domain verification, logs, and webhooks, at $10/month for 10,000 emails once you're past the free tier. If you're also running marketing campaigns and want everything under one account regardless of extra cost and surface area, SendGrid is a reasonable choice — just not the cheaper one for a transactional-only workload.

Frequently Asked Questions
What is Notify?
Notify is a lightweight transactional email API for developers. Per the docs, it sends email through a single endpoint, handles domain verification (SPF/DKIM/DMARC), keeps delivery logs, and offers webhooks on Pro and Scale plans — with no marketing tools, template builder, or bulk-sending features layered on top.
Is SendGrid good for transactional email only?
Yes, technically — SendGrid's Email API supports transactional sending, logging, and webhooks. But its pricing and dashboard are built around a combined transactional-plus-marketing platform, so a team that only needs transactional email ends up paying entry prices closer to $19.95–$89.95/month for a product surface it won't fully use.
How much does Notify cost compared to SendGrid?
Notify: Free (1,000 emails/mo), Pro at $10/month (10,000 emails), Scale at $50/month (100,000 emails). SendGrid's Email API starts at roughly $19.95/month (Essentials, about 50,000 emails) and around $89.95/month on Pro. Notify's entry price is nearly half of SendGrid's, and unlike SendGrid, that price doesn't come bundled with a broader platform — subuser management, email validation credits, dedicated-IP add-ons, a separate Marketing Campaigns product — built for teams sending far more than a transactional-only app typically needs.
What's included in Notify's free plan?
1,000 transactional emails per month, 1 domain, and 48-hour email logs, with no credit card required. Webhooks are available starting on the Pro plan.
Do I need to pay for two products if I only want transactional email with Notify?
No. Notify has one product and one price list — the API, domain verification, logs, and webhooks are all included at each tier. There's no separate marketing product to buy into.
