Anyone can send email. SparkPost delivers.

SparkPost is built for the cloud to work the way developers work today, while providing the unmatched performance the world’s largest email senders require. But doesn’t everyone make similar claims? We invite you to look beyond the marketing spin and compare SparkPost vs SendGrid and others. We’re confident that when you do you’ll see it’s clear why developers and enterprise senders have made SparkPost the world’s fastest-growing email delivery service.

The reliability and scalability of a true cloud platform

When we decided to bring our infrastructure to the cloud we knew we needed to build on a platform that was as focused on performance and reliability as we are on email. That’s why we built our 100% cloud-native SparkPost offering on AWS. SendGrid launched their offering i in self-managed data centers. And that’s where it still sits today.

Unmatched reliability to keep your email in business

SparkPost is proud of our commitment to reliability in offering  cloud email delivery. When you compare SparkPost vs SendGrid under the hood, they’re burdened by legacy technology and have to scramble every time a data center goes down. SparkPost’s modern cloud platform means we can focus on one thing: fast and reliable email delivery.

Instant scalability and elasticity

By leveraging AWS, we offer our customers immediate capacity on-demand — we don’t charge you for extra capacity “just in case” that sits unused while you wait for the unpredictable to happen. Similarly, there’s no hitting the ceiling due to unexpected bursts while you wait for your provider to bring up another server. Need a burst-rate guarantee? We can give you that. Ask SendGrid about theirs.

SparkPost vs SendGrid: Get service level guarantees with teeth

SparkPost has had a service-level guarantee from the start, and recently SendGrid’s begun offering Service Level Agreements, too. But don’t be fooled. Anyone can promise but are their promises meaningful. At SparkPost, our SLAs go deep. We start with sending guarantees and go on to cover UI, data feeds, webhooks, and business continuity. That makes an SLA that only covers a very narrowly defined portion sending sound a little toothless.

The most secure cloud email delivery service

Internally, SparkPost’s security engineering team, lead by our CISO, has invested heavily in securing our application, and their work stands up to audits by some of the most demanding infosec teams at our regulated customers (such as major global banks).

Because we’re built on AWS, our customers benefit from the most secure online environment. They get instant security expertise backed by AWS’ stringent security by design, the most advanced and diligent monitoring systems, and denial-of-service mitigation. Our security team likes to say that AWS goes beyond perimeter security to secure the “squishy middle.”

Add it up, and you’ve got a robust and secure email delivery service that sets the standard for the industry.


Data: you need it and we got it

No more waiting for data.  SparkPost gives all users real time actionable information about the state of your emails. We have 37 different email metrics, everything from injections to opens, from bounces to clicks.  No more scraping through logs or old summarized data, SparkPost gives you everything you need to manage your email streams.

Webhooks like you want them

Email sending doesn’t exists in a vacuum and there are potentially many other 3rd party services you’ll want to tie into. A great way to do this is with webhooks, and that’s why with SparkPost you can have multiple webhooks with different endpoints.

Get your email data in your own warehouse by pointing our servers to your applications and our webhook processes will send data to you every 60 seconds. SparkPost has 18 different events that can be sent to your warehouses. Unlike Sendgrid where all 11 of their events go to the same place, with SparkPost you choose what information goes where — any combination of our webhooks can go to any number of your applications!

In today’s security world it’s important to only relay the information necessary to that process and with SparkPost you can make sure this is the case!

Unmatched email deliverability

Email deliverability matters. Getting email to the inbox is fundamental to how we built the SparkPost service, and it’s no accident that SparkPost has earned the industry’s proven best inbox placement. Why? Our sophisticated technology for global email delivery is unmatched, and no one can beat the experience of the former postmasters, anti-abuse experts, and email pros that make up SparkPost’s deliverability team.

  • 98% inbox delivery for many customers proven by third-party data, better than any other cloud email delivery service
  • Industry’s most experienced deliverability team
  • Dedicated IP address options available at all sending volumes
  • Full support for email authentication and security standards
  • Adaptive Email Network (AEN) optimized  global delivery, made possible by the industry’s most sophisticated bounce code classification, fully addressable queue and real-time intelligent routing rules.

The fastest sending

We average between 1 and 2 seconds for message transit across our network and infrastructure.  SendGrid can take 45 minutes or more; other companies can’t make these promises, because they don’t have the experience and perspective of SparkPost’s experts.

The hardest-working team in the email business

Our first priority is ensuring you rarely need technical support — but we’re here when you do. Along with our comprehensive and straightforward docs and libraries, we provide extraordinary, responsive developer community support  that leverages the channels, like Slack, that developers already know and use.

Unlike others, we don’t make our customers purchase sending volume that they don’t need just to get additional support features. The extra support and hands-on expertise that comes with our Priority, Premium and Enterprise support add-ons are available at any sending volume.

When you compare SparkPost vs SendGrid, you’ll see they recently started offering limited onboarding and consulting services, delivered by a revolving cast of individuals who may have zero previous experience with you or your account. SparkPost delivers full-service support on a first-name basis with an expert who will learn and understand your business. Our Technical Account Managers (TAMs) are assigned, dedicated resources, and they’re backed by a team completely focused on ensuring your success.

­Our Premium and Enterprise customers enjoy the benefit of working with a named TAM from the very start who knows that customer and their email implementation in great detail. They are ­industry experts who understand the business of email at scale, and they stay with you from onboarding to implementation to ongoing support. Their mission is to proactively monitor and manage email operations so you can focus on running your business. If there’s an email event, they’ll proactively contact you for an update – not the other way around.

Alongside our TAMs, our deliverability team is comprised of the most experienced deliverability specialists in the business. ­From managing ISP relationships, troubleshooting, implementing best practices, and overseeing the Adaptive Email Network, our deliverability team helps our customers get the most out of our platform.

Built for developers, by developers

Email is what SparkPost is all about, and we’re completely focused on making a great experience for developers who use our service. Everything we do is focused on making it fast and easy for developers to use the highest-performing email API on the market.

SendGrid is turning away from developers and spending resources to build products for other markets, such as marketing suites. At SparkPost we wear our love for developers and we aren’t going to be distracted from advancing our API based solution. At SparkPost we’re not wavering from our mission of helping developers succeed with email:

  • RESTful API for control of every SparkPost feature: manipulating templates, generating messages, sending emails, and reporting performance data
  • Powerful SMTP injection, including ability to invoke nearly every API feature with SMTP X-Headers
  • Client libraries for Node, PHP, Python, Java and many more, as well as pre-built integration with key cloud platforms like Heroku, Microsoft Azure, and others
  • Webhooks for rich data streaming and inbound message processing
  • Great developer support, including a comprehensive SendGrid migration guide
  • Our UI is built on our own API’s.

The best value in email delivery

SparkPost makes it easy to get started with our generous free offering. Why do we give away 100,000 emails/month for free, forever? Because we can. Our efficient and high-performing cloud platform is unmatched by anyone else. We’re so confident in the performance of our platform — and the value that it provides to our customers — that we give it away for free, in volumes sufficient to allow small start-ups to get off the ground or large senders to test individual mail streams. So go ahead, give it a free test run and experience what real email performance can do for your business.

SparkPost’s transparent pricing and overage charges are cost effective, with plans ranging from 100,000/month to 5 million or more. All sending volume tiers – including free – receive the full scope of Sparkpost features, like subaccounts or dedicated IP capabilities. And if you’d like to purchase add-on services, we don’t exclude small senders there, either.

Other companies can’t come close. In fact, SendGrid won’t even offer you anything beyond a limited, 1-month trial. Go ahead, check their prices and see for yourself.
