It’s a next-gen text vectorizer that supports multiple languages and includes adversarial resilience by default.

It’s a \*\*next-gen text vectorizer that supports multiple languages and includes adversarial resilience by default. This machine learning-driven algorithm discovers spam techniques, keyword stuffing, insertion of glyphs, smart typos, etc, that [threat actors](https://economictimes.indiatimes.com/tech/technology/limited-role-in-pursuing-threat-actors-says-it-ministry-on-iphone-state-sponsored-attack/articleshow/104850829.cms) use to outsmart and bypass security filters and protocols. With the introduction of this **revamped algorithm**, experts are expecting a drastic and evident reduction in phishing and [spamming attacks](https://www.forbes.com/sites/forbestechcouncil/2023/10/24/robocalls-spam-calls-and-cyber-attacks-who-is-responsible-for-protecting-your-organizations-voice-network/?sh=278e53b74c92). > From a product strategy perspective, DMARC reporting is evolving from a security tool to a business intelligence platform, says Brad Slavin, General Manager of DuoCircle. The data in aggregate reports tells you not just who’s spoofing you, but who’s sending legitimate email on your behalf - and whether they’re doing it correctly. ## RETVec’s Development Google deployed and tested RETVec in the past year to determine its efficiency and accuracy. The developers found it to be effective \*\*against email abuses and capable of replacing the [Gmail spam](https://dmarcreport.com/blog/dmarc-google-workspace-gmail-setup-2026/) classifier’s previous text vectorizer to uplift the spam detection rate by 38% and lower the rate of [false positives and negatives](https://www.nospamproxy.de/en/what-is-a-false-positive-and-what-is-a-false-negative/) by [19.4% and 17.71%](https://security.googleblog.com/2023/11/improving-text-classification.html#:~:text=RETVec%20is%20a%20novel%20open,Gmail%20inboxes%20against%20malicious%20emails.), respectively. To make it even better, it’s based on a **lightweight word embedding model** (\~200 parameters) that contributes to the reduction of the size of the transformer’s model. RETVec is special because it can work with any language and all kinds of characters without needing special preparation. _It’s great to be used on your device, on the web, or for sorting through lots of text_. RETVec-trained models also work faster because they use a compact format. Smaller models mean it costs less to compute, and there’s less delay, which is especially important for \*\*big applications and models on your device. With the updated RETVec system, Gmail users may experience enhanced [email security](https://dmarcreport.com/blog/why-email-security-matters-and-how-to-get-it-right/) as [SPF](https://dmarcreport.com/what-is-spf/), [DKIM](https://dmarcreport.com/what-is-dkim/), and [DMARC email authentication protocols](https://dmarcreport.com/what-is-dmarc/) work collaboratively to mitigate the risk of phishing and ensure the **legitimacy of incoming emails**. ![What is dmarc](https://media.mailhop.org/dmarcreport/images/2023/12/what-is-dmarc-26.jpg) ## Will Gmail’s RETVec Impact Email Senders? Yes, it will impact Gmail email senders in a good way. Let’s see how- ## Improved Email Delivery Rate As the [spam detection](https://towardsdatascience.com/spam-detection-in-emails-de0398ea3b48) system becomes more advanced and precise, \*\*genuine emails from trustworthy sources have a higher chance of landing in recipients’ inboxes. _Precise categorization of emails contributes to a clearer understanding of their content, potentially enhancing their successful delivery to the intended recipients_. ## Better Sender’s Reputation The lower number of false positives means that a maximum of the emails you send will be placed in the inboxes instead of spam folders. This reflects you as a trusted sender in the eyes of \*\*email service providers and is likely to reduce the [occurrences of email bounces](https://www.constantcontact.com/blog/why-emails-bounce/) as well. ## Boost in Customer Engagement The opening and [click-through rates](https://en.wikipedia.org/wiki/Click-through%5Frate) of your emails will increase when they will land in the inboxes instead of getting falsely **tagged as suspicious**. _Moreover, as the inboxes of your target audience will be less cluttered, the chances of them noticing and engaging with your messages will increase_. ## Double Up the Security With DMARC ![Dmarc report](https://media.mailhop.org/dmarcreport/images/2023/12/dmarc-report-8745.jpg) _RETVec will do its job in flagging potentially [malicious emails](https://www.independent.co.uk/news/uk/crime/school-email-threat-lockdown-leeds-b2411707.html) by examining their body messages, attachments, **embedded links**, etc._ Now, complementing it with [DMARC](https://dmarcreport.com/) means emails sent by unauthorized senders will fail authentication checks and get marked as spam or rejected. This will bolster the overall email posture of your company. Also, we highly encourage engaging in [safe emailing practices](https://www.techtarget.com/searchsecurity/tip/2019s-top-email-security-best-practices-for-employees) and \*\*adopting Google’s frequent updates to fortify internet menaces. ## Topics [ DMARC ](/tags/dmarc/)[ email security ](/tags/email-security/) ![Vasile Diaconu](https://media.mailhop.org/dmarcreport/images/team/vasile-diaconu.jpg) [ Vasile Diaconu ](/authors/vasile-diaconu/) Operations Lead Operations Lead at DuoCircle.
