When did SendGrid stop feeling like a developer tool and start feeling like a line item in a Twilio invoice? Somewhere between the acquisition and the rebrand to Twilio SendGrid, the thing that made it the default choice — a free tier generous enough to launch a side project on, a Web API v3 you could wire up before lunch, dynamic templates with Handlebars that marketers could edit without a deploy — got buried under upsells, support tiers, and a dashboard that reshuffles itself every quarter.
For years it was the obvious pick. A startup CTO would reach for it the same way they reached for Stripe: nobody got fired for choosing SendGrid.
The cracks show now in the two places that matter most. Deliverability on shared IP pools has gotten genuinely unreliable, with legitimate transactional mail landing in spam and support responses that read like they were drafted by someone three queues away from the problem. And the pricing curve bites hard the moment you cross from hobby volume into real sending — the jump between tiers feels calculated to push you toward a sales call rather than a checkout page.
So the question for anyone staring at their renewal: which of these actually gets your password resets into the inbox without a sales call?

cheaper
EU teams who need data residency and simple pay-per-email pricing
A European cloud provider's transactional email service — GDPR-friendly, pay-as-you-go, and EU-hosted for teams who want SendGrid's function without US data residency.
Pros
- EU-hosted with GDPR compliance
- Simple pay-as-you-go pricing
- Part of broader Scaleway cloud platform
Cons
- Fewer marketing features
- Smaller ecosystem and docs
- Less established deliverability reputation
Best for deliverability — getting mail to the inbox
The number one reason people leave SendGrid is transactional mail landing in spam. Postmark is the gold standard here, keeping transactional and broadcast streams separate so a marketing blast never poisons your password-reset reputation. Sparkpost gives you forensic deliverability analytics for high volume, and SMTP2GO offers detailed spam diagnostics on every send. If inbox placement is the whole reason you're looking, start with Postmark.
Cheapest credible swaps
SendGrid's tier jumps are what push most teams to search. Amazon SES is the rock-bottom option at $0.10 per 1,000 emails if you can handle the AWS plumbing yourself. Resend and MailerSend both ship 3,000 free emails a month with a far friendlier developer experience, and Brevo prices on contacts rather than sends — a better deal for marketing teams with big lists but modest frequency.
Developer experience — modern APIs and docs
If you're tired of SendGrid's cluttered dashboard, Resend rebuilt the whole experience around a clean API and React Email templates. Loops unifies product and marketing email in one modern UI built for SaaS. Mailtrap lets you sandbox and preview emails in staging before anything goes out. These are the picks that make wiring up email feel good again.Which Alternative Is Right for You?
Pick based on what actually drove you to the renewal page. If deliverability was the breaking point — receipts in spam, unanswered support tickets — Postmark is the safest bet, with Sparkpost for enterprise volume. If it was pricing, Amazon SES wins on raw cost, while Resend and MailerSend give you free tiers plus a far nicer API. Marketing teams who want automation and CRM alongside sending should look at Brevo or Mailchimp Transactional. SaaS founders who want one tool for both product and campaign email should try Loops. And EU teams needing data residency have Scaleway TEM or Brevo, both hosted in Europe. Match the tool to your real complaint, not the one with the loudest homepage. Frequently Asked Questions
QWhy is my SendGrid transactional email going to spam?
The most common culprit is SendGrid's shared IP pools, where another sender's bad reputation drags down your deliverability. Many teams switch to Postmark, which keeps transactional streams isolated, or move to a dedicated IP on SES or Sparkpost. Proper SPF, DKIM, and DMARC setup matters regardless of provider.
QWhat is the cheapest alternative to SendGrid for high volume?
Amazon SES is the clear winner on raw cost at roughly $0.10 per 1,000 emails, but you manage deliverability and infrastructure yourself. If you want low cost with a friendlier setup, MailerSend, Brevo, and Scaleway TEM all undercut SendGrid's higher tiers while keeping a usable dashboard.
QIs Postmark or Mailgun a better SendGrid replacement?
Postmark wins on pure deliverability and support quality, making it ideal for transactional mail like receipts and password resets. Mailgun is better if you need inbound email parsing, flexible routing, and validation tooling. For most teams leaving SendGrid over spam issues, Postmark is the stronger first choice.
QWhat happened to Mandrill and is it still an option?
Mandrill is now Mailchimp Transactional and requires a paid Mailchimp Marketing account to use as an add-on. It works well if you already run Mailchimp campaigns, but for standalone transactional email most teams find Postmark or Resend simpler and cheaper to adopt.
QWhich SendGrid alternative is best for a React or Next.js app?
Resend is built for exactly this, with native React Email support so you compose templates as components. Loops is a strong second for SaaS products that need lifecycle and marketing email too. Both offer modern SDKs and free tiers that beat SendGrid's developer onboarding.
