Why people leave SendGrid
SendGrid, now Twilio SendGrid, is proven infrastructure that sends at enormous scale. The complaints are consistent: accounts get suspended for review with slow support to sort it out, the template builder feels a decade old, there is no real AI, and marketing and transactional sit in separate modules. It is built for developers moving volume, not for teams who care what the email looks like in the inbox.
The SendGrid alternative we would pick: SmartMailing
- Brand-perfect email by default. The AI builder reads your website and produces Outlook-safe, on-brand HTML, instead of a blank editor.
- Marketing and transactional on one stack, under one brand, rather than two separate products.
- A per-brand deliverability score and DMARC dashboard, so reputation is visible, not a mystery.
- Inbound replies handled, with AI-drafted, grounded responses rather than a raw webhook.
- EU-operated with GDPR-first handling.
Other SendGrid alternatives worth knowing
- Postmark is the trust benchmark for pure transactional deliverability, with mature inbound parsing.
- Resend is the developer favorite, cheap and clean, and owns the React Email ecosystem.
- Mailgun is solid transactional infrastructure with flexible inbound routing.
If you only need raw API sends, a pure transactional provider is enough. If you need email that looks like your brand, and a marketing side too, that is a different tool.
