Resend vs SendGrid: Pricing, Deliverability and Which Email API to Pick

Resend and SendGrid cost almost exactly the same money. At 50,000 emails a month Resend Pro is $20.00 and SendGrid Essentials is $19.95; at 100,000 Resend Pro is $35.00 and SendGrid Essentials is $34.95. The decision is not about price, because there is barely any price to decide between. It comes down to developer experience, where Resend is clearly ahead, and to dedicated IP rules and account maturity, where SendGrid still has the edge. Neither one permits cold outreach.

Resend vs SendGrid pricing at matched volume

Comparing these two on headline pricing is misleading because the plan names line up differently. Priced at the same volumes, on rates published in August 2026, the ladders are almost identical:

Three of those pairs sit five cents apart. Resend has priced its transactional ladder against SendGrid's and dropped the ninety five cents. Which tells you something useful on its own: these two are not competing on cost, so do not pick on cost.

Two differences in that table do matter. The first is the free plan. Resend's 3,000 emails a month is a permanent allowance, not a trial, though it is capped at 100 emails a day so you cannot batch. SendGrid retired its free forever tier and now offers a 60 day trial at 100 emails a day, after which you pay. If you are running a side project or a low volume internal tool, that difference is the whole decision.

The second is the dedicated IP. SendGrid includes one in the Pro plan at $89.95. Resend charges $30 a month on top of Scale at $90, and gates it further: you have to be sending more than 3,000 emails a day to qualify at all. So a team that needs a dedicated IP at moderate volume can buy one on SendGrid and simply cannot buy one on Resend.

There is also a step on the Resend ladder that most comparisons miss entirely. Resend publishes a Pro tier at $35 a month for 100,000 emails in its machine readable price file, but the slider on the pricing page shows Scale at $90 for that volume instead. The full breakdown, including where overage beats upgrading, is on our Resend pricing page, and the SendGrid ladder is on the SendGrid pricing page.

Which is better for deliverability, Resend or SendGrid?

On raw inbox placement there is no honest winner to declare. Both run reputable shared IP pools, both support DKIM, SPF and DMARC properly, and both will deliver well if you send wanted mail to engaged recipients. Deliverability at this tier is mostly determined by what you send, not by which of these two you pick.

Where they genuinely differ is in how strictly they police you. Resend's Acceptable Use Policy, updated on August 5, 2026, sets a complaint rate ceiling of 0.08% and a bounce ceiling of 4%, and says an account exceeding those "may be shutdown without warning". For scale, Google's bulk sender guidance asks senders to stay under 0.3% complaints. Resend's ceiling is roughly a quarter of that, and there is no graduated review stage described in the policy.

SendGrid is more forgiving in practice, partly because it is an older platform with a broader customer base and a support organization built around remediation rather than shutdown. That cuts both ways. A more permissive platform has more bad senders on its shared pools, which is exactly the argument for buying the dedicated IP that SendGrid bundles into Pro.

The practical read: if your mail is clean and consented, Resend's strictness works in your favor because it keeps the neighbors clean. If your sending is messier, a mailing list you inherited or a re-engagement campaign to lapsed users, SendGrid gives you more room to fix it before you lose the account.

Developer experience is the real difference

This is where Resend earns its position, and it is not close. Resend ships React Email, first party SDKs that feel current, a CLI, and an MCP server so an AI agent can send through it. It publishes its own docs and pricing as machine readable markdown. The API surface is small enough to hold in your head.

SendGrid works, and it has worked for a decade, but it shows its age. The API is larger, the docs are heavier, and the product now lives inside Twilio's site reorganization, which has moved URLs around and made pricing harder to find than it used to be. Teams that have already integrated it rarely regret staying. Teams integrating fresh usually find Resend faster to get to a first sent email.

If your engineers will spend two days on SendGrid and two hours on Resend, that gap is worth far more than the five cents a month between the plans.

Can you use Resend or SendGrid for cold email?

No, and this is the question that sends most people looking at these two down the wrong path entirely. Resend's Acceptable Use Policy prohibits "sending unsolicited messages of any kind, including cold outreach, purchased lists, or scraped contact data". Cold outreach is named directly. SendGrid's policy is functionally the same, and it enforces it through the same complaint and bounce thresholds.

This is not the providers being difficult. A shared relay works because every sender on it keeps complaints near zero. Cold outreach, by definition, goes to people who did not ask, which produces complaint rates that a shared pool cannot absorb. One prospecting campaign can damage placement for every other customer on those IPs, which is why the policies exist.

Outbound needs a different structure: your own domains, your own mailboxes on Google Workspace or Microsoft 365, warmed properly, with volume spread across enough inboxes that no single sender stands out. That is what the right SMTP setup for cold email looks like, and it is why outbound tools are bring your own mailbox rather than shared API relays. We cover the full setup on our cold email infrastructure page.

Should I switch from SendGrid to Resend?

If SendGrid is working and integrated, no. There is no cost saving, the deliverability difference is not material, and a migration costs engineering time plus a fresh reputation warm up on new sending infrastructure. Switching for five cents a month is not a business case.

Switch if one of these is true. You need the permanent free tier for a project that will never justify a paid plan. Your team is genuinely slowed down by the SendGrid integration and would ship faster on modern tooling. Or you are building agent driven email flows and want the MCP server and CLI rather than wiring a REST client yourself.

Stay on SendGrid if you need a dedicated IP below 3,000 emails a day, since Resend will not sell you one at that volume, or if you are already inside Twilio and consolidating vendors has value.

What about Amazon SES?

Worth knowing before you commit to either. Amazon SES costs $10.00 for the same 100,000 emails on a la carte pricing, roughly a third of what Resend or SendGrid charge. The gap is the price of not running SES yourself: no dashboard worth using, sandbox limits to escape, bounce and complaint handling you wire up, and AWS console work every time something changes.

For most teams that trade is worth it, and $25 a month is not a number to reorganize around. For teams already deep in AWS, it usually is. We priced the whole SES ladder from the AWS Price List API on our Amazon SES pricing page.

One planning note that applies whichever you pick. Overage on Resend is $0.90 per 1,000 and it is billed in whole buckets, so a $35 plan can quietly become a $300 bill in a month where a batch job misfires. Email is rarely the biggest line in a software budget, which is exactly why nobody notices it moving, and a good argument for getting alerted when a subscription bill jumps rather than finding out at renewal.

The short answer

Pick Resend if you are building fresh, value developer experience, and want a real free tier. Pick SendGrid if you need a dedicated IP at moderate volume, are already in the Twilio stack, or have a working integration that is not worth touching. Price should not decide it, because the two ladders are five cents apart at every volume that matters.

And if what you actually want to do is send cold outreach, neither one is the tool. Both prohibit it in writing, and both will close the account rather than absorb the complaints. That job needs your own mailboxes and a product built for it.
