SendGrid Alternatives for SaaS Teams in 2026

Prices checked 7 October 2026; each price links to the vendor page it came from.

Why teams leave SendGrid

The first thing to know about SendGrid's Email API pricing page is that it is not expensive at the entry tiers. Essentials starts at $19.95 and its selector reads $19.95 at 50,000 emails and $34.95 at 100,000. Those figures are not where the pain is; it sits in what Essentials leaves out. The feature table shows one additional teammate, two event webhooks, no email validation credits and three days of searchable email activity. For a product with a support team that debugs "I never got the reset email" tickets, three days of history disappears quickly, and longer history is listed as an add-on you buy.

The second pressure point is the step to Pro. Pro starts at $89.95 and covers 100,000 to 2,500,000 emails a month, so a team at exactly 100,000 emails pays $34.95 on Essentials or $89.95 on Pro, $55 more per month. What the extra money buys is listed plainly: one dedicated IP, subuser management, single sign-on, 1,000 teammates, five event webhooks, seven days of activity and 2,500 free validations. Past that, the selector reads $249 at 300,000 emails, $499 at 700,000, $799 at 1,500,000 and $1,099 at 2,500,000, and the page adds that taxes and overages may apply. A team that wants a dedicated IP but nothing else in that bundle is paying for a lot it does not use.

Third, there is no standing free tier for the Email API. The page lists a 60-day trial of 100 emails a day, with no credit card, and then paid plans. SendGrid's separate Marketing Campaigns pricing has its own free plan (2,000 contacts and 6,000 emails a month), plus Basic from $15 and Advanced from $60, priced by contacts. A SaaS team that sends receipts through the API and a monthly newsletter through Marketing Campaigns ends up with two subscriptions, two usage meters and two sets of limits.

The last reason is scope. Everything on the Email API page describes sending: API and SMTP, dynamic templates, event webhooks, suppression management, analytics. Nothing on it triggers a message from a product event such as "trial user invited nobody in three days". That logic lives in your own code or in a lifecycle tool, and the moment a team starts building it, the question of whether the sender and the lifecycle tool should be the same vendor comes up.

The alternatives, one by one

1. Resend: the closest replacement for Essentials

If your complaint is about Essentials, Resend is the cleanest answer, because on the pricing page's transactional tab Pro reads $20 at 50,000 emails and $35 at 100,000. That is five cents either side of SendGrid ($19.95 and $34.95), so the case for moving is the package rather than the price. Its free plan allows 3,000 emails a month, 100 a day and three domains, so a staging domain can carry a trial cutover before any money changes hands; Scale ($160 at 200,000 emails, $350 at 500,000) is the next step up.

The honest trade is the dedicated IP. SendGrid Pro includes one; Resend sells a dedicated IP at $30 a month and only to Scale customers sending more than 3,000 emails a day. Single sign-on is a $150 monthly add-on. Resend's pricing page also has a marketing tab, free at 1,000 contacts with unlimited broadcasts and 10,000 automation runs, and Pro from $40 at 5,000 contacts. A team that runs receipts through SendGrid's API and newsletters through Marketing Campaigns could therefore consolidate in one account. If Resend is on your shortlist, the Resend vs SendGrid page sets the two side by side on sending limits and price.

2. Amazon SES: the cost winner above 300,000 emails

Amazon bills by the message, and the SES pricing page puts Essentials at $0.16 per 1,000 emails. Apply that to SendGrid's selector stops and 300,000 emails cost $48 against $249 on SendGrid Pro, while 1,500,000 emails cost $240 against $799. The page walks through 250,000 outgoing messages as $40.00. SES also sells higher plans: Pro is $0.22 per 1,000 with a $105 monthly charge per account per region, and Enterprise is $0.23 with $500. New accounts start on Essentials, and a standard dedicated IP is $24.95 a month, about a quarter of SendGrid Pro's starting price.

What you give up is the finished product. SendGrid hands you a searchable activity feed, a template editor, a webhook console and a suppression screen; on SES, you assemble the equivalents from SNS, CloudWatch and your own code, and someone has to read the bounce and complaint reports. Choose SES when a named engineer owns deliverability and your volume makes the difference worth about $200 a month; skip it when SendGrid's dashboards were the reason you chose it.

3. Postmark: pay more, keep longer logs

Postmark does not undercut SendGrid on its pricing page. Basic reads $15 at 10,000 emails, $55 at 50,000, $115 at 125,000 and $245 at 300,000, so it costs more than Essentials at 50,000 and 100,000 emails. At 300,000 the picture flips: $245 on Postmark Basic is within a few dollars of SendGrid Pro's $249, and Postmark's default activity retention is 45 days against seven on Pro. If your pain is "support cannot find old messages", that single difference can justify the move; if your pain is the invoice, it will not.

Postmark's dedicated IP starts at $50 a month and is offered to Pro-plan accounts sending 300,000 emails a month or more, so it is not the answer for a team that wants an IP at 100,000. It also has no marketing product to replace Marketing Campaigns. Our Postmark vs SendGrid page covers the head-to-head.

4. Mailgun: 30 days of logs on Scale

For a SendGrid Essentials customer, Mailgun's plan ladder is a step up in cost: Foundation lists $35 for 50,000 emails, and its volume slider reads $75 for 100,000 on the same plan, with Scale at $90 for 100,000, $215 for 250,000 and $400 for 500,000. At 100,000 emails that is roughly two to two and a half times SendGrid Essentials. What the premium buys is a longer window for debugging: Mailgun keeps logs for five days on Foundation and 30 on Scale, where SendGrid gives three days on Essentials and seven on Pro.

Scale and the 100,000-email Foundation plan each come with one dedicated IP, and additional IPs are $59 a month, so an IP at 100,000 emails does not raise the plan price. Mailgun also states that you can send through the US or the EU from a single account. SendGrid's feature table lists EU data residency as well, so treat that as a DPA conversation rather than a reason to switch. The Mailgun vs SendGrid comparison has the rest.

5. Brevo: one account for the API and the newsletter

Brevo prices by the monthly email volume you pick on its pricing page, so the figures to anchor on are starting prices: Starter from $9 and Standard from $18 at 5,000 emails a month, then Professional from $499 for 150,000 to 10 million sends. The free plan allows 300 emails a day and stores up to 100,000 contacts, of which 2,000 can sit in marketing automation. Brevo advertises a 10% discount on yearly billing. Read the slider at your own volume before comparing it with SendGrid's $34.95 at 100,000. Transactional email, campaigns and automation all live in the one account.

It suits a team currently paying for SendGrid's API and its Marketing Campaigns plan, because those two bills collapse into one. It is a campaign-first product, so a developer team that valued SendGrid's API-and-webhooks shape will find Resend or Postmark a more natural fit.

6. MailerSend: more seats for less money

The argument for MailerSend is the seat count, not the sticker price. Its Starter plan is $31.50 a month for 50,000 emails ($378 if billed yearly) and includes five seats and ten domains, where SendGrid Essentials includes a single extra teammate. An FAQ on the page prices 100,000 emails on Starter at $68, so it is dearer than Essentials at both stops, and extra Starter emails run $1.30 per 1,000. Hobby is $6.30 for 5,000 emails, Free is 500 emails a month, and Professional is $99 for 50,000 emails with unlimited users and domains. Pick it when a team of four or five needs access and the volume is modest.

7. Customer.io: when the real gap is lifecycle

Choose Customer.io when the thing SendGrid never did for you, sending a message because of what a user did in the product, is the thing you are now building by hand. Its Essentials plan starts at $100 a month billed monthly for 5,000 profiles and reads $145 at 10,000; one million emails a month are included, transactional email is part of every plan, and the comparison table lists managed deliverability as not included on Essentials. It is a poor way to save money on pure sending, because the bill follows profiles rather than emails. The Customer.io vs Loops comparison sets the two lifecycle tools against each other.

8. Loops: the lightest lifecycle layer

A small SaaS where one founder writes the onboarding emails and wants a single tool for resets, invites and lifecycle sends is the Loops customer. Its free plan keeps contacts unlimited but caps sending at 4,000 in a rolling 30 days to the 1,000 newest contacts; paid plans then follow the subscriber count, $99 a month at 9,998 and $249 at 49,989, with no seat fee and transactional sends included. The price follows the audience, so it is not the tool for several hundred thousand receipts a month, where SES or Resend Scale cost far less.

What it costs at 50,000, 100,000 and 300,000 emails a month

These are sending-priced vendors, so the table uses the same three volumes and says where a vendor has no stop at that level instead of filling the cell with a guess. SendGrid's own selector offers Essentials up to 100,000 and Pro from 100,000.

Read it by tier. If you are on Essentials at 50,000 emails, nothing in the table beats $19.95 except SES at $8, and Resend ties it. You would save about $12 a month by moving to SES, which does not pay for the engineering hours, so Essentials customers should leave for limits, not for the bill. The savings are real on Pro: at 300,000 emails SendGrid reads $249, SES $48, Postmark Basic $245, while Resend's slider reads $160 at 200,000 and $350 at 500,000 with no stop in between. The gap between SendGrid Pro and SES is $201 a month, or $2,412 a year, at that volume.

Dedicated IPs change the 100,000-email maths. SendGrid Pro bundles one at $89.95. Resend Pro at $35 has no IP option, so a dedicated IP means Scale at $90 plus the $30 add-on, $120 in total. Mailgun Scale includes one at $90, and SES plus its $24.95 standard IP comes to $40.95. If a dedicated IP is the real requirement, SendGrid Pro is competitive with the managed options and only SES is clearly cheaper.

When the missing piece is lifecycle email, the unit changes. Customer.io reads $100 at 5,000 profiles and $145 at 10,000, Loops $48 at 4,788 subscribers and $99 at 9,998, and Resend's marketing tab $40 at 5,000 contacts and $80 at 10,000. Those prices follow the people you email, not the number of receipts, and SendGrid's Marketing Campaigns uses the same logic from $15 for Basic. Run the numbers for your own contact count and message count before you assume a lifecycle tool replaces a sender.

Which one for which situation

• You are on Essentials and hit the one-teammate or three-day-log limits: Resend Pro at $20 or $35, MailerSend Starter if you need five seats, or Mailgun Foundation if log retention is the pain.
• You are on Pro for the dedicated IP and send 300,000 or more emails: Amazon SES with a standard dedicated IP, if someone will own the monitoring. The first-year saving at 300,000 emails is about $2,400.
• Support needs to search old messages: Postmark (45 days by default) or Mailgun Scale (30 days). Keep your own copy of message metadata either way.
• You pay for both the Email API and Marketing Campaigns: Resend with its marketing tab, or Brevo, so that one account carries both.
• Nobody owns onboarding and retention email yet: Customer.io if engineering will send events, Loops if a founder or marketer writes the flows. Both include transactional sending.
• You send a few thousand emails a month: Stay on a free or entry plan: Resend Free covers 3,000 a month, MailerSend Free 500 and Brevo Free 300 a day.

Migrating off SendGrid

A SendGrid account usually holds more than one integration, so the order matters more than the speed. The steps below follow the features listed on SendGrid's own pricing page.

1. Inventory what the account does. List the API keys and which services use SMTP versus the REST API, any subusers (Pro and above), dynamic templates, event webhook endpoints, Inbound Parse, branded links, dedicated IPs and IP pools, and every Marketing Campaigns list and automation. Each item needs an owner and a target.
2. Authenticate the new sender beside SendGrid. Add the new vendor's DKIM records and merge its include into the single SPF record for the domain. Keep SendGrid's link-branding records in DNS until the old messages no longer matter, because the tracked links inside those emails resolve through them.
3. Move suppressions before the first send. Export SendGrid's bounces, blocks, spam reports, invalid addresses and unsubscribes, including any group unsubscribes, and load them into the new vendor first. SendGrid classifies bounces into seven categories; the new vendor's names will differ, so map them rather than copying labels.
4. Plan the IP. A dedicated IP does not move with you. If you had one on Pro, the new one starts cold and needs a warm-up ramp (SendGrid's page lists automated warm-up as a feature; the new vendor may leave that to you). If you were on shared IPs, you inherit the new vendor's pool reputation, which you do not control.
5. Rebuild templates. Dynamic templates with conditional blocks do not export into another vendor's syntax. Re-create each template, re-map each variable, and render it with realistic data, including a missing first name and a very long company name.
6. Rewrite the webhook receiver. SendGrid secures its event webhook with signed requests or OAuth 2.0, so the verification code in your handler is SendGrid-specific. Write the new vendor's check, and map event types and payload fields to your database. If you use Inbound Parse, the replacements are Postmark inbound processing, Mailgun inbound routing or SES Mail Manager.
7. Move one message class at a time. Start with receipts or digests, then invitations, and move password resets last because a failed reset locks a customer out. Send a small share through the new path for several days and compare bounce and complaint rates with SendGrid.
8. Export Marketing Campaigns separately. Contact lists, segments and automations are a second migration with a contact-based price on the other side, so import only addresses you would still email.
9. Keep SendGrid for one billing cycle. The Email API page lists no standing free plan, so a fallback means paying at least the $19.95 Essentials starting price until you cancel. That is cheap insurance for one cycle that includes your monthly invoices and digests.

Which to pick first

For a typical SaaS product on Essentials, trial Resend first: pricing is level with SendGrid at 50,000 and 100,000 emails, the plan limits are looser, and its marketing tab can absorb a newsletter list. If you are on Pro and send 300,000 emails or more, the runner-up, Amazon SES, saves around $200 a month and is worth the build if an engineer owns it. If the actual gap is onboarding and retention email, start with Loops or Customer.io and let transactional sending ride along.
