Resend vs SendGrid 2026: Which Costs Less at 50,000 Emails?

At 50,000 emails a month, SendGrid is cheaper by five cents: its Essentials plan costs $19.95 and Resend Pro costs $20. The order changes with volume. The two stay five cents apart at 100,000 emails, Resend is $34 a month cheaper at 300,000 and still ahead at 700,000, and from 1.5 million emails up, SendGrid's Pro plan is the cheaper bill.

Prices were checked on Resend's pricing page and on Twilio SendGrid's email API pricing page on October 18, 2026. SendGrid's page prices its plans at points on a volume slider, and this comparison uses those points. Toolradar data: 10 of the 13 transactional email tools we evaluated have a free plan, according to our transactional email ranking, updated October 2026. Dupple's own newsletters run on beehiiv, not on Resend or SendGrid.

This page compares the two on cost and on the plan details that change the bill. For the wider field at the same volume, the best transactional email APIs list prices the market at 50,000 emails.

Cost at each volume

The table prices one sending account on monthly billing, at list price, with no add-ons, taxes or enterprise contracts. Resend prints a tier table: Pro at 50,000 and 100,000 emails, then Scale tiers from 100,000 to 2.5 million, each with its own overage rate per 1,000 emails once pay-as-you-go is switched on. Each Resend figure below is the cheapest tier-plus-overage combination at that volume. SendGrid's calculator prices only its own stops on the slider, so the table has no SendGrid figure between them.

The middle rows need their arithmetic. At 300,000 emails, the $35 Pro tier covers 100,000 and the other 200 buckets cost $0.90 each, which adds $180 and brings the month to $215. At 700,000, the $350 Scale tier covers 500,000, and the other 200 buckets cost $0.70 each, which adds $140 for a $490 month. Scale's overage rate falls as the tier rises, from $0.80 to $0.46 per 1,000, so above 500,000 emails Scale beats Pro on price, not only on features such as 1,000 domains and a dedicated IP add-on.

SendGrid's bill is harder to pin down between its stops. The calculator gives no price between 50,000 and 100,000 emails, and it publishes no overage rate. The page says only that overage charges may apply on top of the monthly rate. A plan that sends 55,000 emails therefore has no published SendGrid price, while the same month on Resend Pro costs $24.50.

Why 50,000 is close to a tie

At the 50,000 stop the two plans sit $0.05 apart, which is $0.60 a year. Price alone does not settle it, so the plan contents do.

Resend Pro includes 10 domains and no daily send limit. Its dedicated IP add-on, at $30 a month, is sold on Scale to senders who go past 3,000 emails a day, so a Pro account cannot buy one. Extra domains cost $20 a month for 100 more. Single sign-on is a $150 monthly add-on on Scale.

SendGrid's Essentials card lists no dedicated IP. Its Pro plan starts at 100,000 emails for $89.95 a month and includes dedicated IPs, subuser management and single sign-on. If your deliverability depends on an IP of your own, SendGrid includes one from its Pro plan, while Resend offers it only as an add-on on Scale.

Integration: both speak SMTP and HTTP

Both services accept mail over an HTTP API and over SMTP, so an app that sends over SMTP mostly changes its host and credentials to move between them. Resend's pricing page lists a RESTful API, an SMTP relay, official SDKs, batch sending and scheduled emails, and it names React Email, its templating library, in the same feature table. SendGrid's feature list names SMTP and API sending, client libraries, a setup guide, interactive API docs and dynamic templates.

Pick the integration on what your team already writes, and let the table settle the cost. Count last month's sends, including password resets, receipts and alerts, and find the row above that number. The page cannot know that number for you, and it is the input that matters most.

Free tiers: Resend keeps one, SendGrid runs a trial

Resend's free plan is permanent. It covers 3,000 emails a month, capped at 100 a day, with 3 domains. A side project that sends 2,000 emails a month can stay on it indefinitely at $0. For the free tiers of the cloud platforms that host the rest of the app, see cloud free tiers compared.

SendGrid's $0 option is a 60-day trial at 100 emails a day. Its pricing page presents it as the step before a paid plan and lists no permanent free tier. Toolradar's SendGrid listing reads the same way: after 60 days, the account has to upgrade. A project that sends 2,000 emails a month can use the trial for two months, then has to pay.

Where the bill moves

Resend's overage rate is printed for every tier. Each additional bucket of 1,000 emails costs $0.90 on Pro and from $0.80 down to $0.46 on Scale, depending on the tier. Resend describes pay-as-you-go as the way sending continues past the quota, and it has to be enabled first. A month that rises from 50,000 to 60,000 emails costs $29 on Resend Pro, not $20, and a team that regularly sends 70,000 or more is better off on the $35 Pro tier.

SendGrid's overage is not published. Its page says overage charges may apply, and it stops there. For a steady sender that stays on a stop, the gap does not matter much. For a sender with spikes, the unknown rate is the main budget risk.

Neither vendor shows an annual rate. Resend's pricing page says it provides monthly plans only. SendGrid's calculator shows monthly prices only, so the figures above are the ones a monthly account pays.

The 300,000 and 700,000 results are not like for like. SendGrid's Pro price includes dedicated IPs and subuser management, and Resend's Pro plan cannot buy a dedicated IP at all. At 700,000, adding Resend's $30 dedicated IP add-on to the $490 Scale bill makes it $520, which is $21 more than SendGrid Pro. The $34 saving at 300,000 holds only if shared IPs are fine for your mail.

Which one to pick

Pick Resend if your volume stays under 3,000 emails a month for good, or if you send between roughly 300,000 and 700,000 emails a month on shared IPs. Its weakness is the top of the range: at 2.5 million emails its Scale tier is still $51 a month above SendGrid's Pro price, and a dedicated IP is an add-on rather than included. If you are still choosing the backend around the mailer, the best backend-as-a-service platforms list covers the rest of the stack.

Pick SendGrid if you expect volume to pass 1.5 million emails a month, or if you want a dedicated IP included from 100,000 emails up. At 50,000 and 100,000 the five-cent gap is not a reason to choose either. Its weakness is the free option, which is a 60-day trial, and the missing overage rate, which makes a spiky month hard to budget. For functions that send mail on a schedule, best serverless platforms shows where those jobs usually run.

How we priced it

Prices were checked on October 18, 2026. Resend's figures come from its pricing page and the tier table it publishes for each plan: Free at $0, Pro at $20 for 50,000 and $35 for 100,000 emails, Scale from $90 for 100,000 up to $1,150 for 2.5 million emails, and the overage rate printed for each tier. SendGrid's figures come from the volume calculator on Twilio's pricing page, at the stops shown in the table. Toolradar's listings for SendGrid and Resend were checked for the free-tier wording.

Every row assumes one sending account, monthly billing, list prices before tax, and no discounts, add-ons or enterprise contracts. Resend's overage is computed at the published rate of the tier it sits on: each Resend total is the tier price plus that tier's rate for each 1,000 emails over the tier's included volume, and the table shows the cheapest such combination.

FAQ

Is Resend or SendGrid cheaper in 2026?

At 50,000 and 100,000 emails a month, SendGrid's Essentials plan is cheaper by $0.05, which is a tie in practice. Resend is cheaper at 300,000 and 700,000 emails on its published tiers, and SendGrid is cheaper again at 1.5 million and 2.5 million. A dedicated IP changes the middle of that range, because SendGrid Pro includes dedicated IPs and Resend sells it as an add-on on Scale.

Does Resend or SendGrid have a free plan?

Resend has a permanent free plan with 3,000 emails a month, capped at 100 a day. SendGrid's $0 option is a 60-day trial at 100 emails a day, and its pricing page lists no permanent free tier. Toolradar's SendGrid listing says the same.

How much does Resend cost at 100,000 emails a month?

It costs $35 a month on the Pro 100K tier. The $20 Pro tier with overage would cost $65 for the same volume, so the larger tier is the cheaper choice. Resend's Scale plan lists $90 for 100,000 emails, which adds 1,000 domains, a Slack channel and access to the dedicated IP add-on.

How much does SendGrid cost at 100,000 emails a month?

Essentials costs $34.95 a month at 100,000 emails on SendGrid's calculator. Its Pro plan starts at 100,000 emails for $89.95 and adds a dedicated IP, subuser management and single sign-on. SendGrid publishes no overage rate, so a month above the stop has no published price.

Which is cheaper above 300,000 emails?

It depends on the volume. At 700,000 emails, Resend's Scale 500K tier with overage costs $490 against $499 for SendGrid Pro. At 1.5 million, Resend's Scale tier costs $825 against SendGrid's $799, and at 2.5 million SendGrid is $51 a month cheaper. SendGrid publishes no price between its stops, so the table cannot settle the volumes in between.
