SendGrid Is Now Twilio.com: What It Means for Email Senders

On February 26, 2026, sendgrid.com went away. The URL now redirects to twilio.com, where Twilio has folded SendGrid, Segment, and its core communications products under one roof. If you are a SendGrid customer, your email API still works exactly as before — but the rebrand raises a fair question: is SendGrid still the right choice, or is this a good moment to look at what else is out there?

This guide explains what actually changed, what it means for current SendGrid users, and how SendGrid stacks up against the strongest transactional email alternatives in 2026.

What Actually Changed (and What Didn’t)

The February 2026 consolidation was a website and branding move, not a product change. SendGrid’s Email API, Marketing Campaigns dashboard, and support infrastructure are all intact. Your existing API keys, domain authentication settings, dedicated IP configurations, and billing relationships are unaffected.

What changed:

• sendgrid.com now redirects to twilio.com
• Documentation moved to twilio.com/docs/sendgrid
• The SendGrid standalone brand is being absorbed into Twilio’s identity

What stayed the same:

• API endpoints — no migration required
• Pricing plans and billing
• The app dashboard at app.sendgrid.com
• Deliverability infrastructure, shared and dedicated IPs
• SDKs and client libraries

Twilio’s stated motivation: customers who use SendGrid for email often don’t realize that Twilio also offers SMS, voice, identity verification, and customer data tools. A unified web presence makes cross-product discovery easier. For SendGrid users who only need email, this adds no friction and minimal benefit. As Twilio explained in their announcement, this is about presenting a unified platform story — the products themselves have not changed.

Quick-Pick Summary

• Staying on SendGrid: Right for teams already integrated, sending mixed transactional and marketing email, or relying on Twilio’s broader ecosystem
• Switch to Postmark: Better choice when inbox placement for transactional email is the top priority and you need strict content standards
• Try Mailgun: Worth evaluating if you need inbound email parsing, or if Mailgun’s pricing model works better at your volume
• Consider Amazon SES: The economics get compelling above 200,000 emails/month, but it demands significant engineering time to set up and maintain

SendGrid (Now Twilio SendGrid Email API)

SendGrid is the most widely used email API in the world. Twilio acquired it in 2019 for approximately $3 billion, and the infrastructure is substantial. For teams already integrated, there is rarely a compelling reason to migrate simply because the website moved.

Where SendGrid excels:

• High sending volume with proven, global infrastructure
• Granular deliverability tooling: dedicated IPs, IP warmup automation, email validation API, and an Event Webhook that delivers real-time data for every send, bounce, open, and click
• Mature SDKs covering Node.js, Python, Ruby, Go, PHP, Java, and C#
• Marketing Campaigns module for bulk newsletters alongside the transactional API, so you do not need a second platform
• A free trial that allows 100 emails/day — enough to validate integration before paying anything

Pricing:

• Free: 60-day trial at 100 emails/day (no credit card required)
• Essentials: $19.95/month for up to 100,000 emails
• Pro: $89.95/month for up to 2.5 million emails
• Premier: custom pricing for higher volumes

The weaknesses you need to know: SendGrid’s pricing has no middle tier between Essentials and Pro. Teams sending 150,000–500,000 emails/month pay Pro rates ($89.95) despite not using most of the plan’s features. Shared IP reputation can vary — on Essentials, you share IPs with other senders whose practices you cannot control. Customer support quality has received consistent criticism; escalating a deliverability or billing issue to a human can take days. And now that SendGrid documentation lives inside twilio.com, search results and site navigation mix email content with SMS, voice, and identity — making it harder to find what you need quickly.

Postmark: The Deliverability Specialist

Postmark is the strongest alternative when inbox placement for transactional email is the top priority. The company has maintained separate IP pools for transactional versus bulk email since its founding, and it publishes deliverability metrics openly. Their strict content enforcement policy keeps spam ratios low across shared infrastructure — which directly benefits every customer’s inbox placement.

Pricing:

• Free: 100 emails/month, permanent (no trial expiry — useful for development)
• Basic: $15/month for 10,000 emails; $1.80 per 1,000 additional emails
• Pro: $16.50/month for 10,000 emails; $1.30 per 1,000 additional emails
• Platform: $18/month for 10,000 emails; $1.20 per 1,000 additional emails

For teams sending primarily password resets, order confirmations, and other system-triggered email, Postmark’s per-email deliverability is consistently the best in the category. Pricing from Postmark’s pricing page has remained stable, and the overage structure makes costs predictable.

The weaknesses you need to know: Postmark does not allow cold outreach or promotional bulk campaigns. If you want marketing email and transactional email on one platform, Postmark is not it. At very high volumes (millions of emails/month), the per-email math favors SendGrid or Amazon SES over Postmark’s overage rates. There is also no built-in subscriber management, automation workflows, or landing page builder — it is a pure sending infrastructure product.

Mailgun: Developer Infrastructure with Inbound Routing

Mailgun has been a popular SendGrid alternative for developers who want capable email infrastructure without a marketing layer on top. It is particularly strong at one thing SendGrid dropped years ago: inbound email parsing. If your application needs to receive and process incoming email — support ticket creation from email replies, for example — Mailgun handles this natively.

Mailgun is now owned by Sinch, a Swedish communications platform, in a move that parallels what Twilio is doing with SendGrid. The branding is shifting toward Sinch, but the product continues to function under the Mailgun name and infrastructure.

Pricing starts around $15/month for 10,000 emails on the Foundation plan. A 30-day free trial with 1,000 emails/month lets you test the API before committing. Pricing can shift, so verify current rates directly on Mailgun’s pricing page before budgeting.

The weaknesses you need to know: Mailgun’s dashboard and documentation have improved over the years but remain less polished than SendGrid’s. Support response times on lower-tier plans lag behind Postmark’s. Deliverability on shared IPs is solid, but does not consistently reach Postmark’s level for pure transactional sends. The Sinch integration roadmap also introduces some uncertainty about where the product is headed.

Amazon SES: Low Cost at Scale, High Setup Cost Everywhere

Amazon Simple Email Service is the lowest-cost option for high-volume sending, but it requires significantly more technical work than the alternatives above.

Pricing:

• $0.10 per 1,000 emails (charged per recipient)
• No monthly minimum on the base rate
• Dedicated IPs: $24.95/month per IP (standard) or $15/month per account plus $0.08/1,000 emails (managed)
• Virtual Deliverability Manager: additional $0.07 per 1,000 emails

At 1 million emails/month, the base SES cost is $100 — compared to $89.95/month just to reach the SendGrid Pro tier base. For teams already on AWS, the savings become compelling above roughly 200,000 emails/month.

The weaknesses you need to know: SES is raw infrastructure. There is no marketing UI, no template library, no subscriber management — just an API. Deliverability configuration (domain verification, DKIM, DMARC, bounce handling, suppression lists) is entirely your responsibility. Before you can send to external recipients at all, you must move out of the SES “sandbox” by submitting an AWS support request and waiting for approval — which can take 24–48 hours and requires explaining your use case. AWS free-tier support does not include delivery issues; meaningful support access starts at $29/month on the Developer plan.

How to Choose

The right choice depends on your sending volume, technical resources, and whether you need marketing email in the same platform as transactional email.

Stay on SendGrid if you are already integrated and campaigns run smoothly, you send a mix of transactional and marketing email through one API, or your team uses other Twilio products and wants consolidated billing.

Switch to Postmark if inbox placement for transactional sends is your primary concern, you send only system-triggered email (no bulk newsletters), and you want a provider with published deliverability standards that hold all customers accountable.

Choose Mailgun if you need inbound email parsing or routing built into the API, or if Mailgun’s pricing works out better at your specific sending volume after running the numbers.

Choose Amazon SES if you send 200,000+ emails/month and have engineering capacity for setup and ongoing maintenance. The economics are compelling; the operational overhead is real.

The Bottom Line

SendGrid’s move onto Twilio.com is a branding consolidation, not a product change. If you are a happy SendGrid customer, nothing requires action. If you have been waiting for a reason to evaluate alternatives, this is as reasonable a moment as any — the migration friction is the same whether you switch today or next year.

Postmark leads for pure transactional deliverability and opinionated infrastructure. Mailgun is worth considering if inbound routing matters to your use case. Amazon SES offers the best economics at scale for teams willing to manage infrastructure themselves.

SendGrid remains one of the most capable and widely supported email APIs available. The Twilio umbrella provides long-term stability — Twilio is a $10 billion public company, not a startup that might sunset the product. The primary complaints are about pricing structure and support responsiveness, not reliability or features.
