Resend Alternatives in 2026: Postmark, SendGrid, and Brevo, Priced Today
We live-checked Resend, Postmark, SendGrid, and Brevo pricing today. Here is what each plan actually costs, what the free tiers really allow, and which one to pick for a real transactional email workload.
Decision Brief
What to do with this research
Resend is the fastest setup for a developer shipping React-based transactional email, but it is not automatically the right pick. Postmark is the cheapest real production tier here ($15/month) and is built specifically for triggered mail, not bulk sends. SendGrid, now sold under Twilio, earns its higher entry price with dedicated IPs and enterprise-grade sending infrastructure once you're past 100k emails a month. Brevo is the only one of the four that bundles transactional email with marketing contacts under one free daily allowance, and its paid tiers start at $9/month for the Starter plan.
Use the conclusion, then validate live pricing and plan limits before buying.

Amplitude Alternatives in 2026: What PostHog, Mixpanel, Heap, and GA4 Actually CostRead the next related article.This is a buying screen for developers replacing or evaluating Resend for transactional email - the auth, receipt, password-reset, and notification mail a SaaS product sends on a trigger, not the newsletter or marketing blast a growth team sends on a schedule. We live-checked pricing for Resend, Postmark, SendGrid, and Brevo directly against each vendor's pricing page on 2026-07-12 rather than repeating numbers that may have been current eight months ago and are not current now.
Quick Decision
If you are already deep into React Email templates and want the fastest developer setup, stay on Resend - its free tier alone (3,000 emails/month) will carry a pre-revenue app for months. If cost per email matters more than developer polish and you are sending purely transactional mail, Postmark at $15/month is the cheapest verified transactional-only production tier in this comparison. If you are already inside the Twilio ecosystem or expect to outgrow 100,000 emails/month soon, SendGrid scales further with dedicated IPs built in. If you want transactional email and marketing contacts under one login, Brevo's Starter plan at $9/month is the cheapest paid entry point of the four.
What each vendor actually costs today (checked 2026-07-12)
Resend
| Tier | Price | Emails/month | Daily cap | Domains |
|---|---|---|---|---|
| Free | $0 | 3,000 | 100/day | 1 |
| Pro | $20-$35/mo | 50,000-100,000 | None | 10 |
| Scale | $90-$1,150/mo | 100,000-2,500,000 | None | 1,000 |
| Enterprise | Custom | Custom | None | Flexible |
Overage on Resend runs from $0.90 per 1,000 emails at the low end of Pro down to $0.46 per 1,000 at the top of Scale. A dedicated IP is a $30/month add-on once you're past roughly 3,000 emails/day. Resend also sells a separate Marketing (contacts/broadcast) product with its own free tier (1,000 contacts) and paid tiers from $40-$650/month - do not confuse that with the transactional pricing above if you only need triggered email.
Postmark
| Tier | Price | Emails/month | Overage (per 1,000) | Domains | Retention |
|---|---|---|---|---|---|
| Free | $0 | 100 | N/A | - | - |
| Basic | $15/mo | From 10,000 | $1.80 | 5 | 45 days |
| Pro | $16.50/mo | From 10,000 | $1.30 | 10 | Up to 365 days |
| Platform | $18/mo | From 10,000 | $1.20 | Unlimited | Customizable |
Postmark's free tier (100 emails/month) is realistically a testing tier, not a production launch tier - it will not cover a live app's password resets past its first day. Every paid tier starts at the same 10,000-email floor and scales up from there; what changes between Basic, Pro, and Platform is retention length, domain limits, and the per-email overage rate, not the starting price gap you might expect. Add-ons include dedicated IPs from $50/month and DMARC monitoring from $14/month per domain.
SendGrid (Twilio)
| Tier | Price | Emails/month | Notes |
|---|---|---|---|
| Free trial | $0 for 60 days | 100/day | 100 contacts, not a permanent free tier |
| Essentials | From $19.95/mo | 50,000-100,000 | Basic analytics, 1 extra teammate |
| Pro | From $89.95/mo | 100,000-2,500,000 | Dedicated IPs included, SSO, subuser management |
| Premier | Custom | 5,000,000+ | Dedicated IP pooling, automated warm-up |
SendGrid does not publish a flat overage rate for emails sent past your plan's included volume - Twilio's own support documentation states the exact amount varies month to month, so check your account or Twilio's Overage Rates support page for your current plan's rate rather than assuming a fixed per-1,000 number. The important structural point: SendGrid does not have a permanent free production tier the way Resend and Brevo do. Its "Free" option is a 60-day trial, after which you are on Essentials or nothing.
Brevo
| Tier | Price | Emails/month |
|---|---|---|
| Free | $0 | 300/day |
| Starter | $9/mo | From 5,000 |
| Standard | $18/mo | From 5,000+ (higher sending limits than Starter) |
| Professional | $499/mo | From 150,000 |
| Enterprise | Custom | Custom |
Brevo's official pricing page confirms these figures directly in the vendor's own server-rendered structured pricing data, so they did not require loading the page in a browser to obtain. Contact allowances varied between our two page captures (one showed "up to 100K contacts," another showed a different figure on a different pricing sub-page), which is a sign that contact-list pricing specifically can vary by route or session state - so confirm your contact-list cost at brevo.com/pricing with your actual list size selected, even though the plan and email-volume prices above are confirmed.
Free tier reality check
Not all four "free tiers" mean the same thing, and conflating them is the most common mistake in Resend-alternative roundups:
| Vendor | Free tier | Is it production-usable? |
|---|---|---|
| Resend | 3,000/month, 100/day cap | Yes - covers a pre-revenue app's auth and notification email for months |
| Postmark | 100/month, no stated cap detail beyond that | Testing only - will not survive a live app's first real day |
| SendGrid | 100/day for 60 days, then gone | No - it is a trial, not a tier; budget for Essentials from day one |
| Brevo | 300/day, no stated monthly expiry | Yes, if 300/day (roughly 9,000/month) covers your volume; the paid Starter tier ($9/month) picks up from there |
If your actual constraint is "keep this app on a free plan for as long as possible," Resend and Brevo are the two real options. Postmark and SendGrid's free offerings exist to let you test integration, not to run a live product on.
Who should actually pick each one
Pick Resend if you're a developer-first team already writing React Email templates, you want the fastest signup-to-first-send path, and your volume is comfortably under 100,000 emails/month. It is also the strongest option if you want a free tier that survives longer than a trial. See our full Resend vs SendGrid comparison if you're weighing developer experience against enterprise deliverability controls specifically.
Pick Postmark if your mail is exclusively transactional - password resets, receipts, one-time codes - and you want the cheapest verified entry price with a reputation built around not sharing IP pools with bulk marketing senders. Postmark has historically enforced this separation strictly; do not route newsletter or promotional sends through it, since that is the fastest way to get a Postmark account flagged for review.
Pick SendGrid if you're already inside the Twilio ecosystem (SMS, voice, verify), you expect to cross 100,000+ emails/month within the next year, or you specifically need dedicated IP warm-up and subuser management for a multi-brand product. Its entry price is the highest of the three verified vendors here, and that premium buys infrastructure maturity, not a better free tier.
Pick Brevo if the deciding factor is having transactional email and marketing contacts in one tool with one login, and either the 300-emails/day free tier or the $9/month Starter plan (5,000 emails/month) fits your volume. It's the cheapest paid entry point in this comparison if your contact-list size stays modest - just confirm your contact-list pricing at brevo.com/pricing since that figure varies by list size and wasn't consistent across our checks. Our broader best transactional email tools roundup and Resend software profile cover where Brevo and the other three rank against a wider field if you want more than four options.
Honest cons and migration risk
- Resend: youngest company of the four, smallest support surface, and its Scale tier's top price ($1,150/month for 2.5M emails) is not obviously cheaper than SendGrid Pro at similar volume once you actually price both against your real send count.
- Postmark: no meaningful free production tier, and its strict transactional-only policy means you cannot casually send a one-off announcement blast through the same API key without risking review.
- SendGrid: no permanent free tier at all past the 60-day trial, and its historical deliverability reputation has been more mixed in independent sender-reputation reports than Postmark's - verify current sender-score data for your use case rather than assuming parity.
- Brevo: plan and email-volume pricing is confirmed and stable, but contact-list allowances varied between our two page captures - budget time to confirm your exact contact-list cost at signup before you commit engineering time to integration.
Migration cost across all four is mostly the same shape regardless of which pair you're moving between: you re-verify sending domains (SPF/DKIM/DMARC), you re-point webhook endpoints for bounce and open events, and you lose whatever sender-reputation history you built on the old provider's shared or dedicated IP. Budget at least a few days of DNS propagation and bounce-rate monitoring before cutting over production traffic, not just an afternoon of API-key swapping.
A trial plan that actually tests the risk that matters
Week one: send your actual transactional templates - not "hello world" - through a real domain with SPF/DKIM configured, and confirm bounce and open webhooks land correctly. Week two: intentionally trigger a bounce and a spam complaint (a disposable test address works) and confirm the vendor's suppression list updates automatically, since a provider that keeps retrying suppressed addresses will eventually hurt your domain reputation. Week three: check what happens at the edge of your free or entry tier - does sending stop, degrade, or silently overage-bill you - before you find out in production.
The bottom line
For most small teams replacing Resend, the honest ranking is: stay on Resend's free tier as long as it lasts, move to Postmark Basic when you need the cheapest transactional-only paid option, move to SendGrid when dedicated IPs and Twilio-scale infrastructure actually matter, and pick Brevo's Starter plan when you also want marketing contacts bundled in at the lowest paid entry price of the four.

Frequently Asked Questions
Which Resend alternative is actually the cheapest for a small app?
Postmark's Basic plan is the cheapest real, production-ready paid tier we could verify: $15/month for 10,000 emails as of 2026-07-12. Resend's free tier (3,000 emails/month, 100/day cap) can cover an early-stage app longer before you need to pay anything, but once you outgrow it, Resend's Pro plan starts at $20/month.
Is Brevo actually cheaper than Resend, Postmark, or SendGrid?
For low volume, yes. Brevo's Starter plan is $9/month for 5,000 emails/month, undercutting Postmark's $15/month entry price, and its free tier (300 emails/day, no stated monthly expiry) is real and verified. Once you scale past a few thousand emails a month the comparison depends on your exact volume - Brevo's Standard tier is $18/month and Professional is $499/month for 150,000+ emails/month.
Do these vendors charge for the emails you don't send?
No. All four price around included monthly (or daily, for Brevo's free tier) volume plus an overage rate once you exceed it. Postmark's overage ranges from $1.20 to $1.80 per 1,000 extra emails depending on plan; Resend's ranges from $0.46 to $0.90 per 1,000; SendGrid does not publish a flat overage rate for extra emails - it varies by plan and month, so check your account or Twilio's support documentation for the current rate on your plan. None of the four require you to pre-purchase a block you might not use, but unused included volume also does not roll over month to month on any of them.
