SendGrid
EmailSendGrid is a high-volume transactional and marketing email API with dedicated IPs, strong deliverability tooling, and detailed analytics, backed by Twilio's scale. The catch is support: slow responses and occasional account suspensions, reflected in a low Trustpilot score.

At a glance
What each SendGrid alternative is best for
- Resend
4.8 / 5
- Resend is a developer-first email API for React and Next.js teams. The catch is no HIPAA BAA, US-only data storage, and reports of abrupt account suspensions.
- OneSignal Email
4.7 / 5
- OneSignal Email offers a generous free tier within its multichannel push platform. The catch is email is secondary to its core push product and less mature than specialists.
- Postmark
4.6 / 5
- Postmark is a transactional email service with strong deliverability and streams that isolate message types. The catch is no marketing focus, no HIPAA BAA, and US-only data storage.
- Brevo
4.5 / 5
- Brevo is a GDPR-first, EU-based platform bundling email, SMS, WhatsApp, and CRM. The catch is it is not a purpose-built transactional provider, with strict anti-abuse suspensions.
- Loops
4.5 / 5
- Loops bundles marketing, lifecycle, and transactional email for SaaS teams with automated deliverability setup. The catch is a young company with no SOC 2, HIPAA, or EU data residency.
- Customer.io
4.4 / 5
- Customer.io is a lifecycle messaging platform with deep behavioral segmentation and a visual workflow builder. The catch is a steep learning curve and profile-based pricing that climbs with your audience.
- AWS SES
4.3 / 5
- Amazon SES sends high-volume email through AWS at among the lowest costs at scale. The catch is a bare-bones service with no template editor, campaign UI, or analytics.
- Mailgun
4.2 / 5
- Mailgun is a developer email API with strong deliverability and validation tooling and an EU region. The catch is inconsistent deliverability and support quality across reviews.
- Mandrill
4.2 / 5
- Mandrill is a transactional email add-on tightly integrated with the Mailchimp ecosystem. The catch is it requires a paid Mailchimp plan and will not sign a BAA.
- MailerSend
4.1 / 5
- MailerSend is a developer-focused transactional email and SMS API from the MailerLite team, with EU-hosted data by default, a real free tier, and built-in email verification. The catch is no formal SOC 2 Type II or HIPAA, and reports of accounts suspended over bounce-rate triggers.
- SparkPost
4.0 / 5
- SparkPost (now Bird) is a high-volume email API with strong deliverability and analytics. The catch is no HIPAA BAA and poor reviews since the 2023 Bird rebrand.
- Mailjet
4.0 / 5
- Mailjet is a GDPR-certified email service with EU data storage and a drag-and-drop editor. The catch is a 200-per-day free cap and reports of inconsistent deliverability.
FAQ
Common questions
The strongest SendGrid alternatives depend on what you need. Resend rates highest among the options here; the comparison table covers price, free tier, and rating, and the "what each alternative is best for" section matches each option to a use case.
Yes. Several alternatives offer an ongoing free tier, including Resend. Check the "Free tier" column above; free allowances and limits vary by provider, and some offers are trials rather than perpetual free tiers.
SendGrid supports both. Its Email API and SMTP relay handle transactional messages like password resets, receipts, and alerts, while its Marketing Campaigns product covers newsletters and promotional sends. Many teams adopt it primarily for high-volume transactional delivery and add marketing features as needed.
No. SendGrid's own documentation states it is not a HIPAA Eligible Service and that Twilio does not sign a Business Associate Agreement (BAA) for SendGrid. Teams handling Protected Health Information should not rely on SendGrid for HIPAA-covered workloads.
Paid plans start with the Essentials tier at $19.95 per month, which covers up to 50,000 emails per month. Higher Essentials and Pro tiers scale by volume, up to millions of emails per month, and add features like dedicated IP addresses, subusers, and priority support. Premier is custom priced for very high volume senders, and separate Marketing Campaigns plans are priced by contacts.
Yes, on eligible plans. SendGrid offers EU data residency for email, storing and primarily processing recipient PII, content, and event data in EU data centers. You must send through EU-designated APIs and SMTP endpoints for data to stay in the EU. Check current plan documentation to confirm which tier your account needs.
Often, yes. Courier sits in front of these providers behind one API, so you can route through SendGrid or an alternative, or fail over between them, without rewriting your integration each time.
