Why people leave SendGrid
SendGrid has been around forever, and in email years, that's both a blessing and a curse. It scales well and Twilio isn't going anywhere. But the cracks are showing. With 583 Trustpilot reviews painting a bleak picture - nearly all 1-star - the complaints are remarkably consistent: nonexistent customer support with days-long response times, lost account data, punitive overage charges, and unilateral changes to service terms. Multiple reviewers describe it as the worst support experience in decades. To understand modern email platform expectations, read our guide to best email marketing tools for SaaS.
The DX problem
When Resend launched with React Email and a beautiful API, it made SendGrid's developer experience feel ancient. If you've used both, you know the difference. Modern SDKs, cleaner docs, fewer workarounds needed. Check our SendGrid comparison page to see how it stacks up against modern alternatives.
The deliverability lottery
SendGrid lets almost anyone sign up. This means the shared IP pools can have reputation issues from other users. Some months you're fine, other months your emails are hitting spam. Platforms like Postmark that vet customers aggressively, or Mailtrap that runs transactional and bulk email on completely separate IP pools, don't have this problem. Learn more about email deliverability best practices to understand why this matters.
Marketing that feels bolted on
SendGrid's marketing features exist, but they feel like an afterthought. If you need serious marketing automation with AI-generated sequences, purpose-built tools like Sequenzy, Loops, or Customer.io are significantly better experiences.
The alternatives, honestly
| SendGrid problem | Best alternative | Why |
|---|---|---|
| Developer experience feels dated | Resend | Modern SDKs, cleaner docs, React Email support, and simpler local development. |
| You need transactional + marketing for SaaS | Sequenzy or Loops | One lifecycle email platform instead of SendGrid plus a separate marketing tool. |
| Shared IP deliverability is inconsistent | Postmark or Mailtrap | Stricter sender controls or separated pools reduce reputation spillover. |
| Raw cost matters at massive volume | Amazon SES | Cheapest send cost if your team can own deliverability and tooling. |
| Email is one notification channel among many | Knock or Novu | Better orchestration for push, SMS, in-app, and user preferences. |
| E-commerce revenue attribution matters | Klaviyo | Store-native flows, product recommendations, and cart recovery beat SendGrid Marketing Campaigns. |
Best SendGrid alternative for SaaS teams
Sequenzy gives you transactional and marketing in one platform with AI content generation. Describe what you want ("a 5-email onboarding sequence for a project management SaaS") and it writes the emails. Stripe syncs customer data automatically.
It's built for SaaS teams who are tired of SendGrid's dated interface but need more than just transactional. See our SendGrid comparison for detailed feature breakdown.
Best SendGrid alternative for developers
If SendGrid's DX is your main complaint and you only need transactional email, Resend is the obvious choice. Best developer experience in email, hands down. The catch: zero marketing features. Check our Resend comparison page for more details.
| Developer workflow | SendGrid | Resend |
|---|---|---|
| API ergonomics | Mature but dated | Clean, modern, TypeScript-friendly SDKs. |
| Template workflow | Dashboard templates or custom HTML | React Email-native component workflow. |
| Local testing | Possible, but clunky | Easier to integrate into modern app stacks. |
| Marketing email | Included, but basic | Not included. |
| Best fit | Teams already standardized on Twilio/SendGrid | New products that want excellent transactional DX. |
Best cheap SendGrid alternative for high-volume email
At $0.10 per 1,000 emails, nothing beats SES on raw cost. But you get zero help - no templates, no dashboard, no deliverability tools. Only choose this if you have engineering resources to build everything yourself.
Best SendGrid alternative for multi-channel notifications
Both Knock and Novu go beyond email to handle push, SMS, in-app, and chat notifications in a single API. If SendGrid is just one piece of your notification puzzle, these platforms replace multiple services at once. Novu is open-source if that matters to you.
Best SendGrid alternative for e-commerce
SendGrid's marketing features are terrible for e-commerce. Klaviyo has deep Shopify integration, abandoned cart flows, and revenue attribution that SendGrid can't touch. Expensive but the ROI math works for stores doing real volume.
Best SendGrid alternative for deliverability
Postmark is the strongest pick if your complaint is password resets, receipts, or onboarding emails landing in spam. Mailtrap is the more flexible option when you want strong deliverability controls but also need bulk or marketing email on the same account. The key is separating critical transactional traffic from lower-performing campaign traffic, which SendGrid's shared-pool experience can make harder.

The pricing comparison
At 50,000 emails/month:
| Provider | Approx. 50k-email cost | Best for | Hidden cost |
|---|---|---|---|
| SendGrid Essentials | $19.95/month | Cheap mixed transactional and basic marketing | Dated DX, support complaints, and shared reputation risk. |
| Mailtrap | $20/month | Deliverability analytics and separated traffic pools | Smaller ecosystem than SendGrid. |
| Resend | $20/month | Developer-first transactional email | You need another marketing platform. |
| Postmark | $50/month | Critical transactional deliverability | Strict approval and limited marketing depth. |
| Amazon SES | ~$5/month | Lowest raw send cost | You build templates, dashboards, reputation monitoring, and support workflows. |
| MailerSend | $28/month | Modern transactional dashboard | Less SaaS lifecycle marketing depth. |
| Sequenzy | $49/month for 120k emails (unlimited subscribers) | Marketing + transactional + AI for SaaS | Not a pure infrastructure-only API replacement. |
Note: Some prices are per subscriber (Sequenzy, Loops) while others are per email (SendGrid, Resend). Compare based on your actual usage. See our pricing page for a detailed breakdown.
When SendGrid is still the right choice
SendGrid wins if:
| Stay with SendGrid when... | Switch when... |
|---|---|
| You are sending millions of emails and need proven scale. | You are early enough that switching APIs is still cheap. |
| You have already built extensively around their API. | Your integration is thin and mostly sends transactional templates. |
| Twilio ecosystem integration is valuable to you. | Twilio bundling is not part of your broader infrastructure. |
| You are on the Pro plan with dedicated IPs and premium support. | You are on shared infrastructure and support delays affect production. |
| Marketing Campaigns are good enough for your needs. | You need lifecycle automation, AI content, or product-led messaging. |
Don't switch just because the grass looks greener. If SendGrid is working well at scale, the switching cost might not be worth it. But if you're frustrated with the DX, inconsistent deliverability, or clunky marketing, the alternatives are genuinely better now.
