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 and how you are billed
• Support contacts and account managers
• Deliverability infrastructure, shared and dedicated IPs
• SDKs and client libraries

One later change did touch infrastructure. In August 2026, Twilio retired SendGrid’s legacy public IP addresses used to connect to the API and SMTP service, with temporary disablement windows on August 24, 25 and 27 and permanent removal scheduled for August 31. It affects only customers who hard-coded those IP addresses in applications, mail servers or firewall allowlists instead of using hostnames. Dedicated sending IPs are not affected. Use smtp.sendgrid.net, api.sendgrid.com or api.eu.sendgrid.com for EU accounts. Twilio’s status page marked the maintenance completed on September 15, 2026.

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 cheapest option per email, but it demands significant engineering time to set up and maintain

SendGrid (Now Twilio SendGrid Email API)

SendGrid is one of the most widely used email APIs, and Twilio has owned it since 2019. 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). The permanent free plan was discontinued in May 2025.
• Essentials: from $19.95/month, with price rising by volume
• Pro: from $89.95/month, includes dedicated IP addresses, subuser management and SSO
• Premier: custom pricing for higher volumes

The weaknesses you need to know: Dedicated IP addresses come only with Pro and up, so the jump from $19.95 to $89.95 is the price of controlling your own IP reputation. On Essentials you share IPs with other senders whose practices you cannot control. Support quality is a common complaint in user reviews, though we have not measured response times. And now that SendGrid documentation lives inside twilio.com, search results and site navigation mix email content with SMS, voice, and identity, so it is 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. Its strict policy against cold outreach and bulk promotion is meant to keep spam rates low across shared infrastructure, which 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 focus on a single use case is the main reason to pick it. Pricing on Postmark’s pricing page was unchanged when we rechecked it on October 5, 2026, and the overage structure makes costs predictable. Dedicated IPs start at $50/month per IP and require 300,000+ emails/month on Pro or higher.

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 inbound email routing and 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 at $15/month for 10,000 emails on the Basic plan, with Foundation at $35/month for 50,000 emails and Scale at $90/month for 100,000. There is a free plan at 100 emails/day, and Foundation and Scale include a free first month. Dedicated IPs cost $59/month per IP. Verify current rates 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. Live chat and phone support start on the Scale plan. The Sinch integration roadmap also introduces some uncertainty about where the product is headed.

We cover the head-to-head details in our SendGrid vs Mailgun comparison.

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:

• Pay-as-you-go: $0.10 per 1,000 outbound emails, no monthly minimum
• Subscription plans (new): Essentials at $0 base and $0.16 per 1,000, Pro at $105/month base and $0.22 per 1,000, Enterprise at $500/month base and $0.23 per 1,000 (rates for the first 10 million emails/month)
• Dedicated IPs: $24.95/month per IP (standard) or $15/month per account plus a per-email fee (managed)
• Virtual Deliverability Manager: $0.07 per 1,000 emails for the first 10 million per month

The plan-based pricing is the main change since this article was first published. The $0.10 rate still applies as the à la carte option, and the subscription plans bundle deliverability features on top of it.

At 100,000 emails/month, pay-as-you-go SES costs $10, against SendGrid’s $19.95 entry price, and at 1 million emails/month the SES base cost is $100. SendGrid includes dedicated IPs from its Pro plan (from $89.95/month), while on SES a dedicated IP is a $24.95/month add-on. SendGrid prices higher volumes through a calculator, so check your own volume on its pricing page before comparing.

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 requires explaining your use case. AWS technical support is a separate paid plan, so check what your support tier covers before relying on it for delivery issues.

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 high volume, already run on AWS, and have engineering capacity for setup and ongoing maintenance. The per-email cost is low; 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 is the pick when pure transactional email and strict sending rules matter most. Mailgun is worth considering if inbound routing matters to your use case. Amazon SES has the lowest per-email price for teams willing to manage infrastructure themselves.

SendGrid remains one of the most capable and widely supported email APIs available. Twilio is a public company and has kept the Email API running through the rebrand. The primary complaints are about pricing structure and support responsiveness, not reliability or features.
