Route to Workers, automate your email processing

Cloudflare Email Routing has quickly grown to a few hundred thousand users, and we’re incredibly excited with the number of feature requests that reach our product team every week. We hear you, we love the feedback, and we want to give you all that you’ve been asking for. What we don’t like is making you wait, or making you feel like your needs are too unique to be addressed.

That’s why we’re taking a different approach - we’re giving you the power tools that you need to implement any logic you can dream of to process your emails in the fastest, most scalable way possible.

Today we’re announcing Route to Workers, for which we’ll start a closed beta soon. You can join the waitlist today.

How this works

When using Route to Workers your Email Routing rules can have a Worker process the messages reaching any of your custom Email addresses.

Even if you haven’t used Cloudflare Workers before, we are making onboarding as easy as can be. You can start creating Workers straight from the Email Routing dashboard, with just one click.

Email Routing Insights

Email Routing Insights

Have you ever wanted to try a new email service but worried it might lead to you missing any emails? If you have, you’re definitely not alone. Some of us email ourselves to make sure it reaches the correct destination, others don’t rely on a new address for anything serious until they’ve seen it work for a few days. In any case, emails often contain important information, and we need to trust that our emails won’t get lost for any reason.

To help reduce these worries about whether emails are being received and forwarded - and for troubleshooting if needed - we are rolling out a new Overview page to Email Routing. On the Overview tab people now have full visibility into our service and can see exactly how we are routing emails on their behalf.

Routing Status and Metrics

The first thing you will see in the new tab is an at a glance view of the service. This includes the routing status (to know if the service is configured and running), whether the necessary DNS records are configured correctly, and the number of custom and destination addresses on the zone.

Below the configuration summary, you will see more Continue reading

Our journey so far

Back in September 2021, during Cloudflare’s Birthday Week, we introduced Email Routing as the simplest solution for creating custom email addresses for your domains without the hassle of managing multiple mailboxes.

Many of us at Cloudflare saw a need for this type of product, and we’ve been using it since before it had a UI. After Birthday Week, we started gradually opening it to Cloudflare customers that requested access through the wait list; starting with just a few users per week and gradually ramping up access as we found and fixed edge cases.

Most recently, with users wanting to set up Email Routing for more of their domains and with some of G Suite legacy users looking for an alternative to starting a subscription, we have been onboarding tens of thousands of new zones Continue reading

Attack Maps now available on Radar

Attack Maps now available on Radar

Cloudflare Radar launched as part of last year’s Birthday Week. We described it as a “newspaper for the Internet”, that gives “any digital citizen the chance to see what’s happening online [which] is part of our pursuit to help build a better, more informed, Internet”.

Since then, we have made considerable strides, including adding dedicated pages to cover how key events such as the UEFA Euro 2020 Championship and the Tokyo Olympics shaped Internet usage in participating countries, and added a Radar section for interactive deep-dive reports on topics such as DDoS.

Today, Radar has four main sections:

  • Main page with near real-time information about global Internet usage.
  • Internet usage details by country (see, for example, Portugal).
  • Domain insights, where searching for a domain returns traffic, registration and certificate information about it.
  • Deep-dive reports on complex and often underreported topics.

Cloudflare’s global network spans more than 250 cities in over 100 countries. Because of this, we have the unique ability to see both macro and micro trends happening online, including insights on how traffic is flowing around the world or what type of attacks are prevalent in a certain country.

Radar Maps will make this information even richer Continue reading

Easily creating and routing email addresses with Cloudflare Email Routing

Easily creating and routing email addresses with Cloudflare Email Routing

Over four billion people — or half of the world’s population — have at least one email address, many of whom use it as an essential tool to stay on top of their personal and professional matters. More than 300 billion emails are sent and received every day, but seeing email as just a communications tool wouldn’t do it justice. Its impact in our lives goes far beyond being a vessel for messages — its use cases also cover being a common way of validating one’s identity online, and serving as the gateway for other communication platforms.

Today, most people use their email for sensitive purposes, such as logging in to their bank account, or communicating with governmental entities. At the same time, they will use that email to sign up for a 10% off coupon they found online, which will surely spam them for months to come. Despite these two use cases being polar opposites in relation to importance and security, people take the risk, usually for the sake of conveniently managing one account.

Much in the same way, businesses want to have different email addresses for different types of inquiries, such as sales and support, but often find Continue reading

Announcing Project Turpentine: an easy way to get off Varnish

Announcing Project Turpentine: an easy way to get off Varnish

When Varnish and the Varnish Configuration Language (VCL) were first introduced 15 years ago, they were an incredibly powerful combination to configure caching on servers (and your networks). It seemed a logical choice for a language to configure CDNs — caching in the cloud.

A lot has changed on the Internet since then.

In particular, caching is just one of many things that “CDNs” are expected to do: load balancing, DDoS protection, rate limiting, transformations, synthetic responses, routing and more. But above all what “CDNs” need to be is programmable, not just configurable.

Configuration went from a niche activity to a much more common — and often involved — requirement. We’ve heard from a lot of teams that want to remove critical dependencies on the one person they have who knows how to make configuration changes — because they’re the only one on the team who knows how to write in VCL.

But it’s not just about who can write VCL — it’s what VCL is increasingly being asked to do. A lot of our customers have told us that they have much greater expectations for what they expect the network to do: they don’t just want to configure Continue reading

Discovering what’s slowing down your website with Web Analytics

Discovering what’s slowing down your website with Web Analytics

Web Analytics is Cloudflare’s privacy-focused real user measurement solution. It leverages a lightweight JavaScript beacon and does not use any client-side state, such as cookies or localStorage, to collect usage metrics. Nor does it “fingerprint” individuals via their IP address, User Agent string, or any other data.

Cloudflare Web Analytics makes essential web analytics, such as the top-performing pages on your website and top referrers, available to everyone for free, and it’s becoming more powerful than ever.

Focusing on Performance

Earlier this year we merged Web Analytics with our Browser Insights product, which enabled customers proxying their websites through Cloudflare to evaluate visitors’ experience on their web properties through Core Web Vitals such as Largest Contentful Paint (LCP) and First Input Delay (FID).

It was important to bring the Core Web Vitals performance measurements into Web Analytics given the outsized impact that page load times have on bounce rates. A page load time increase from 1s to 3s increases bounce rates by 32% and from 1s to 6s increases it by 106% (source).

Now that you know the impact a slow-loading web page can have on your visitors, it’s time for us to make Continue reading

Working with those who protect human rights around the world

Working with those who protect human rights around the world

Over the past few years, we’ve seen an increasing use of Internet shutdowns and cyberattacks that restrict the availability of information in communities around the world. In 2020, Access Now’s #KeepItOn coalition documented at least 155 Internet shutdowns in 29 countries. During the same period, Cloudflare witnessed a five-fold increase in cyberattacks against the human rights, journalism, and non-profit websites that benefit from the protection of Project Galileo.

These disruptive measures, which put up barriers to those looking to use the Internet to express themselves, earn a livelihood, gather and disseminate information, and participate in public life,  affect the lives of millions of people around the world.

As described by the UN Human Rights Council (UNHRC), the Internet is not only a key means by which individuals exercise their rights to freedom of opinion and expression, it “facilitates the realization of a range of other human rights” including “economic, social and cultural rights, such as the right to education and the right to take part in cultural life and to enjoy the benefits of scientific progress and its applications, as well as civil and political rights, such as the rights to freedom of association and assembly.” The effect of Continue reading
