TL;DR: My top SendGrid alternatives in 2026 are Postmark for fast, reliable transactional mail, Amazon SES for the lowest cost at volume, and Mailgun or Resend for developer-friendly APIs. Paid entry plans run from $10 to $20 a month, and SES charges $0.10 per 1,000 emails, as of October 2026. I compare 8 options on price, free tiers, dedicated IPs and fit.
Twilio started retiring SendGrid’s free Email API plan on May 27, 2025. After a 60-day transition, sending paused on free accounts.
That one change pushed a lot of small SaaS teams to look around. Today, SendGrid’s pricing page offers a 60-day trial capped at 100 emails a day. After that, Essentials starts at $19.95 a month.
Price is not the only reason people leave. Some want faster support. Some want a cleaner API. Others want a dedicated IP without jumping to an $89.95 plan.
I compared 8 providers that solve one or more of those problems. If you want the full market first, read my guide to the best transactional email services for SaaS. If you want to model costs at your volume, my transactional email pricing breakdown does the math by tier.
Quick Comparison: 8 Best SendGrid Alternatives
| Provider | Best For | Starting Price | Key Feature |
|---|---|---|---|
| Postmark | Fast, reliable transactional mail | $15/mo for 10,000 emails | Separate transactional and broadcast streams |
| Amazon SES | Lowest cost at high volume | $0.10 per 1,000 emails | Pay only for what you send |
| Mailgun | Closest feature match to SendGrid | $15/mo for 10,000 emails | Free plan with 100 emails a day |
| Resend | Modern developer experience | Free for 3,000 emails/mo | Built by the React Email team |

| Bird (SparkPost) | Deposit-based billing at scale | $15 deposit at $0.40 per 1,000 | Unused balance carries forward |
What Makes a Great SendGrid Alternative?
A good SendGrid alternative sends your password resets and receipts to the inbox quickly, costs less at your real volume, and gives you clear logs when something breaks. It should support SPF, DKIM and DMARC setup out of the box. It should also offer webhooks, solid SDKs and a dedicated IP path once you outgrow shared pools.
SendGrid sets a decent baseline. It has a large API surface, marketing tools and Twilio’s scale behind it. So the bar is not “can it send email”. Every provider here can.
The real test is fit. Here’s what I check first:
- Inbox placement for transactional mail, which depends a lot on who shares your IPs.
- Price at your volume, not at the cheapest tier on the page.
- Log retention, so support can answer “did my email arrive?” a week later.
- Dedicated IP rules, including the minimum volume each vendor expects.
- Compliance help with the Gmail, Yahoo and Microsoft sender rules.
If a provider covers those five, it’s a real alternative. The rest comes down to taste and budget.
Why Are Teams Leaving SendGrid in 2026?
Most teams leave SendGrid over the loss of the free plan, the jump in price for a dedicated IP, or support response times on lower tiers. Twilio retired the free plan in 2025 and now offers only a 60-day trial. A dedicated IP is included from the Pro plan, which starts at $89.95 a month on SendGrid’s pricing page as of October 2026.
Let me break those down.
The free plan is gone. Per Twilio’s changelog, free accounts lost sending after the transition. Contacts above 100 were deleted on free Marketing Campaigns accounts. If you ran a side project on the free tier, you had to pay or move.
Dedicated IPs cost more. SendGrid’s Email API pricing lists no dedicated IP on Essentials. Pro includes one. That’s a big step if you only want to isolate your reputation.
It’s part of a larger company. Twilio completed its SendGrid acquisition in February 2019. Email is now one product among many. Some buyers like that. Others want a vendor that does only email.
None of this makes SendGrid bad. It still works well for many teams. But if any of these points hurt, the options below are worth a look.
Best SendGrid Alternatives for Transactional Email
These four are where I’d start if your main job is app email: sign-ups, resets, receipts and alerts.
#1 Postmark: Best for fast, reliable transactional mail
Postmark is the pick I’d make for most SaaS products that care about inbox speed more than marketing features.
What it does well. Postmark keeps transactional and bulk mail apart using message streams. Your password resets don’t share a pool with someone’s newsletter. That design choice is the main reason developers recommend it.
Key features:
- Separate transactional and broadcast streams.
- 45 days of message history on paid plans by default.
- Templates, webhooks and inbound email processing.
- Dedicated IPs for high senders on Pro and above.
Pricing. Postmark’s pricing page shows a free developer tier of 100 emails a month. Basic is $15 a month for 10,000 emails, with $1.80 per extra 1,000. Pro is $16.50 and Platform is $18 at the same volume, with lower overage. Dedicated IPs start at $50 a month for senders above 300,000 emails a month, as of October 2026.
Best for: SaaS apps where a late login email means a lost user.
Limitations. Postmark is strict about content. It’s built for transactional mail, so heavy marketing users may feel boxed in. ActiveCampaign acquired Postmark in 2022, so it’s also no longer independent.
#2 Amazon SES: Best for lowest cost at high volume
If you send a lot and have engineers who can wire things up, nothing on this list beats SES on price.
What it does well. SES is raw sending at cloud prices. You pay per message with no monthly plan. It fits teams already on AWS who want email in the same account as the rest of their stack.
Key features:
- Pay as you go with no plan tiers.
- Standard and managed dedicated IP options.
- Virtual Deliverability Manager for extra insight.
- Native fit with Lambda, SNS and other AWS services.
Pricing. The SES pricing page lists $0.10 per 1,000 emails and $0.12 per GB of attachments. A standard dedicated IP is $24.95 a month. Managed dedicated IPs cost $15 a month per account plus a per-email fee. New AWS accounts can get up to $200 in credits under the current free tier, as of October 2026.
Best for: High-volume senders on AWS with in-house engineering.
Limitations. New accounts start in a sandbox. The SES docs limit sandbox accounts to 200 messages per 24 hours and verified recipients only. There’s no template builder or friendly dashboard. You build those yourself.
#3 Mailgun: Best for the closest feature match to SendGrid
Mailgun is the most like-for-like swap. The API, logs and routing feel familiar if you come from SendGrid.
What it does well. Mailgun has been a developer email API for a long time. It covers sending, inbound routing, logs and analytics. Unlike SendGrid today, it still has a free plan.
Key features:
- Free plan with 100 emails a day.
- Inbound routing and parsing.
- Longer log retention on higher plans.
- Dedicated IP access on Foundation and Scale volumes.
Pricing. Mailgun’s pricing page lists Basic at $15 a month for 10,000 emails. Foundation is $35 for 50,000 and Scale is $90 for 100,000. Log retention runs from 1 day on Basic to 30 days on Scale, as of October 2026.
Best for: Teams that want a direct replacement with minimal relearning.
Limitations. One day of logs on Basic is short. Mailgun is owned by Sinch, which completed its purchase of Pathwire in 2021, so it’s also part of a large CPaaS company. I compare the two directly in SendGrid vs Mailgun.
#4 Resend: Best for modern developer experience
Resend is the newer API that many JavaScript teams reach for first.
What it does well. Resend’s team also maintains React Email, an open source way to build emails as components. If your product is in Next.js or Node, the setup is short and the docs are clean.
Key features:
- Free plan with 3,000 emails a month.
- Simple SDKs for popular languages.
- 30 days of data retention on all plans.
- Dedicated IP add-on on Scale.
Pricing. Resend’s pricing page shows the free plan at 3,000 emails a month with a 100 per day cap. Pro is $20 for 50,000 emails. Scale is $90 for 100,000. Extra emails cost $0.90 per 1,000. A dedicated IP is $30 a month on Scale for senders above 3,000 emails a day, as of October 2026.
Best for: Developer-led startups that want to ship email in an afternoon.
Limitations. It’s younger than SendGrid or Mailgun. Advanced features like deep analytics are thinner. The free plan’s 100 per day cap is tight for launches.
Best Budget and SMTP-Friendly SendGrid Alternatives
These two suit smaller apps, WordPress sites and teams that mostly need a reliable SMTP relay.
#5 SMTP2GO: Best for a simple SMTP relay with a free tier
SMTP2GO is plain and does its job. That’s the appeal.
What it does well. It gives you SMTP and an API with a usable free tier and clear plan steps. It’s easy to plug into apps, servers and WordPress plugins.
Key features:
- Free plan with 1,000 emails a month.
- SMTP relay and REST API.
- 30 days of reports on paid plans.
- Dedicated IP included on Professional.
Pricing. SMTP2GO’s pricing page lists Starter at $10 a month for 10,000 emails and Professional at $75 for 100,000. Extra emails cost $1 per 1,000 on Starter and $0.85 on Professional, as of October 2026.
Best for: Small apps and agencies that want SMTP without fuss. See my list of the best SMTP relay services for more.
Limitations. Fewer developer extras than Resend or Postmark. The dashboard is functional rather than modern.
#6 MailerSend: Best for small teams that want templates
MailerSend sits between a pure API and a marketing tool.
What it does well. Non-developers can build templates in a visual editor while engineers call the API. That split works well for small product teams.
Key features:
- Free plan with 500 emails a month.
- Drag and drop and HTML template editors.
- API, SMTP and webhooks.
- Dedicated IPs on Enterprise for high senders.
Pricing. MailerSend’s pricing page lists a free plan of 500 emails a month and a Hobby plan for 5,000 emails a month at under $10. Starter and Professional cover 50,000 emails a month. Prices showed a discount when I checked, so confirm the current figure on the page. Dedicated IPs are for Enterprise accounts sending over 100,000 emails a week.
Best for: Teams where marketing or support edits email copy.
Limitations. The free plan is small. Dedicated IPs need Enterprise.
Best SendGrid Alternatives for Marketing Plus Transactional
SendGrid bundles Marketing Campaigns with the API. If you use both, these two cover the same ground.
#7 Brevo: Best for marketing plus transactional in one account
Brevo is a full marketing platform that also sends transactional mail through an API and SMTP.
What it does well. You get campaigns, automation, a CRM and transactional email under one login. For a small SaaS team, that can replace two tools.
Key features:
- Free plan with up to 300 emails a day.
- Transactional API and SMTP on every plan.
- Marketing automation and CRM.
- Dedicated IP on Enterprise.
Pricing. Brevo’s pricing page lists a free plan of 300 emails a day and Starter at $9 a month for 5,000 emails, as of October 2026. Dedicated IPs sit in Enterprise, which is priced through sales.
Best for: Small teams who want one vendor for newsletters and app mail.
Limitations. Brevo is marketing first. Developers who only want an API may find it heavier than they need. I’d still keep transactional and marketing on separate subdomains, as I explain in transactional vs marketing email.
#8 Bird (SparkPost): Best for deposit-based billing at scale
SparkPost is now part of Bird, formerly MessageBird. It’s an enterprise sender with a low per-email rate.
What it does well. MessageBird bought SparkPost for about $600 million in 2021 to compete with Twilio. Today, Bird sells email through deposits that you spend at a per-1,000 rate.
Key features:
- Free plan with 1,000 emails a month.
- Per-1,000 pricing funded by deposits.
- Unused balance carries forward.
- Dedicated IP add-ons and IP pools on Growth and Scale.
Pricing. Bird’s email pricing page lists Startup at a $15 deposit and $0.40 per 1,000 emails. Growth is a $250 deposit at $0.45 per 1,000, and Scale is $1,000 at $0.35 per 1,000, as of October 2026. The free plan stops at 1,000 emails a month and 50 a day.
Best for: Teams sending millions a month who want SES-like rates with more tooling.
Limitations. The deposit model takes getting used to. Bird does not list the price of a dedicated IP add-on on that page.
How Should You Choose the Right SendGrid Alternative?
Start with your monthly volume and your team’s skills. Under 50,000 emails a month, Postmark, Resend or Mailgun are easy wins. Above a million, SES or Bird usually cost far less. If non-developers edit templates, look at MailerSend or Brevo. Then check log retention and dedicated IP rules before you commit.
Here’s the order I’d work through.
1. Price it at your real volume. Entry plans hide the real cost. Mailgun Scale and Resend Scale both list $90 for 100,000 emails. SES at the same volume is $10 in sending fees. My pricing guide lays this out at 10k, 50k, 100k and 1M.
2. Decide on shared or dedicated IPs. Most apps under 100,000 emails a month do fine on good shared pools. Dedicated IPs need steady volume to build a reputation.
3. Check the sender rules. Gmail’s sender guidelines require SPF, DKIM and DMARC for bulk senders since February 2024. Yahoo set the same date and asks you to keep your spam rate below 0.3%. Microsoft started sending non-compliant mail from domains above 5,000 messages a day to Junk on May 5, 2025, according to Petri. Every vendor here supports those records. My email deliverability guide walks through setup.
4. Look at logs and support. Short log windows make support tickets painful. Postmark’s 45 days and Resend’s 30 days are comfortable. Mailgun Basic’s 1 day is not.
5. Plan the migration. Move one stream at a time. Start with low-risk mail like internal alerts. Then move resets and receipts once DNS records pass.
How I Evaluated These SendGrid Alternatives
I did not run send tests for this guide. I compared each vendor’s published pricing page, plan limits and docs as of October 2026. I also read ownership announcements and the public sender requirements from Gmail, Yahoo and Microsoft.
I scored each provider on five things:
- Published price at 10,000, 50,000 and 100,000 emails a month.
- Free tier or trial terms, including daily caps.
- Dedicated IP rules and the volume each vendor expects.
- Developer fit: API, SMTP, SDKs, webhooks and log retention.
- Ownership and focus, since that shapes product direction.
Every price links to its source. Vendors change pricing often, so check the live page before you buy. You can read more about how I work in my editorial policy.
The Bottom Line
If you want the safest move off SendGrid for app email, pick Postmark. It’s built for transactional mail and keeps it apart from bulk sends. If cost is the driver and you have engineers, Amazon SES is hard to beat at $0.10 per 1,000 emails. If you want a near drop-in replacement, Mailgun is the closest match. And if you live in React or Next.js, Resend is the fastest setup.
For WordPress or simple SMTP, SMTP2GO is fine. If marketing edits templates, MailerSend or Brevo make sense.
My next step for you: price your top two choices at your real volume. Then read Postmark vs SendGrid or Amazon SES vs SendGrid for the head-to-head detail.
Frequently Asked Questions
Does SendGrid still have a free plan?
No. Twilio began retiring SendGrid’s free Email API and Marketing Campaigns plans on May 27, 2025, with a 60-day transition. As of October 2026, SendGrid’s pricing page offers a 60-day free trial limited to 100 emails a day instead. After the trial, Essentials starts at $19.95 a month.
What is the cheapest SendGrid alternative?
Amazon SES is the cheapest at volume. It charges $0.10 per 1,000 emails, plus $0.12 per GB of attachments, as of October 2026. For small senders who want a free plan instead, Resend offers 3,000 emails a month, SMTP2GO offers 1,000 and Mailgun offers 100 a day. Pick based on your real monthly volume.
Is Postmark better than SendGrid for transactional email?
For pure transactional email, many developers prefer Postmark. It separates transactional and broadcast mail into different message streams, so app emails don’t share reputation with bulk sends. SendGrid offers more marketing features and a larger platform. If your main job is resets and receipts, I’d lean Postmark.
Who owns SendGrid?
Twilio owns SendGrid. Twilio completed the acquisition in February 2019, and SendGrid now sits inside Twilio’s communications platform alongside SMS and voice. Its pricing pages now live on twilio.com. Paid SendGrid plans were not affected when Twilio retired the free plan in 2025.
How hard is it to migrate away from SendGrid?
Most migrations take days, not weeks. You add the new provider’s SPF and DKIM records, update DMARC if needed, swap API keys or SMTP settings and rebuild templates. Move low-risk mail first, then resets and receipts. Keep SendGrid active until bounces and delivery on the new provider look normal.
