The WebVitals.tools Monthly Digest

WebVitals.tools is an open-source reference for Core Web Vitals. We ship daily, but most readers don't want to consume daily. The monthly digest is the right cadence for staying current on web performance without doom-scrolling our blog index. Each issue contains the new posts from the past month, a refresh on the benchmarks dashboard, and one or two editor picks -- often a deep-dive that we drafted but didn't publish, or a primary source we're working through.

If you've been following the field for a while, the digest is also where we run our retrospectives -- six-month checkpoints on framework comparisons, infrastructure benchmarks that drift over time, and methodology updates we've learned from. The digest is the only place we publish those retrospectives in long form before they become permanent reference material on the site.

Subscribe

If your email client opens an awkward draft window, you can also email newsletter@webvitals.tools with the subject "Subscribe" and we'll add you manually within 24 hours. We are intentionally keeping the subscribe path low-tech while we evaluate hosted newsletter providers.

What you'll receive

Each issue follows the same structure. We have heard the feedback that newsletters that change their format every issue are exhausting; the WebVitals.tools digest deliberately uses the same five-section template every time so you can scan in 30 seconds and read in 10 minutes.

1. This month at a glance. One paragraph, no fluff. What we shipped, what changed in the field, and one number from the benchmarks dashboard worth knowing.
2. New posts. Three to five new posts since the last issue, each with a one-line summary and a direct link.
3. Benchmark refresh. The numbers on our dashboard that moved more than two percentage points since last month, with a note on why they moved.
4. Editor picks. One or two outside reads -- a paper, a primary source, a thoughtful blog post -- that influenced our writing this month.
5. What's coming. The shape of next month's content. Not promises, but signals.

Issues run 600 to 900 words. We aim for a five-minute read on mobile and never break that target. The footer always contains a one-click unsubscribe and a link to view the issue in your browser.

Preview: what the May 2026 issue will cover

Subscribe today and the May issue will reach you Monday morning. The first Monday cadence means we never compete with weekend backlog or Tuesday-after-a-launch scheduling chaos.

Why subscribe instead of bookmarking?

Three reasons this newsletter beats the bookmark-and-forget pattern. None of them are growth-hack reasons.

• Forcing function for the editor. The newsletter forces us to summarize the month into a single coherent narrative every 30 days. That summarization process catches gaps and over-reaches that we miss inside individual posts. Subscribers get the cleaned-up view.
• You get the changes that don't justify a full post. Many performance-relevant developments -- a Chrome flag flip, a CrUX schema update, a third-party tag manager that suddenly slimmed down -- don't deserve a 2000-word writeup. They land in the digest as 50-word notes. Subscribers see them; non-subscribers don't.
• Lower discovery cost. Following 30 daily posts is exhausting; a single monthly email isn't. Engineers we've spoken with say they bookmark intent-to-read posts and reach inbox-zero on them once a quarter, if ever.

Privacy

We collect your email address and nothing else. We do not embed tracking pixels, web beacons, or click-through trackers. Open rates and click rates are not measured. Plain HTML, plain text fallback, plain unsubscribe -- the same conventions we'd use ourselves. The privacy policy lives at our about page until we publish a standalone privacy doc; in short: your email is used only to send you this newsletter, and only by the editorial team at WebVitals.tools. We do not sell, share, or rent the list. We do not run "list cleaning" services that resell address lists in aggregate.

If you change your mind, you can unsubscribe via the link at the bottom of every issue or by replying with "unsubscribe" in the subject line. We process unsubscribes within 24 hours. We will keep your email on a suppression list (so a future signup form re-subscription does not accidentally re-add you) unless you request full deletion, in which case we delete the address from our suppression list within seven days.

Editorial standards

Every issue follows the same editorial standards as the rest of the site. We cite primary sources (Chrome User Experience Report, HTTP Archive, RFC documents, framework changelogs) before secondary commentary. We re-run benchmarks before re-publishing data. We mark every fix or recommendation with the version of the framework or platform we tested against. The full standards write-up lives on our methodology page; the short version is that we do not link or recommend anything we have not tested ourselves in the past 60 days.

If you spot an error, reply directly to any issue. We treat factual corrections as the highest-priority issue category, ahead of feature work. The complete error log is on our changelog.

Read first, subscribe later

If you'd rather sample the content before subscribing, the Best of Q1 2026 roundup is the right place to start. It curates the 12 most-shared posts from our launch month, organized by topic. From there, the blog index covers everything in reverse chronological order, and the sitemap groups every page on the site by topic. Decide whether the writing fits your taste, then come back here when you're ready.

Thanks for considering. We're glad you're here.
