EmailFlow OS is a Loom alternative for one job: B2B cold outreach by email. You record one video, EmailFlow OS creates a personalized version for each recipient on your prospect list and sends every email through your own Brevo account and your own domain. Loom is a video messaging tool you share by link; EmailFlow OS is the sending system around the video.
As of October 2026. Everything said about Loom on this page comes from Loom’s own pricing page and its page on Loom for sales. Check both before you decide; plans and features change.
Both tools start from one recording. Where they differ is what happens after it:
Stay with Loom if your videos are mainly for your own team or for customers you already talk to: screen recordings with a camera bubble, comments and emoji reactions, integrations such as Slack and GitHub, and on Business + AI automatic meeting notes, summaries and chapters. EmailFlow OS does none of that. It is built for one task: reaching people who do not know you yet, with one video that each recipient receives in a version made for them, sent from your domain.
New accounts start with 20 free credits and no credit card. The trial credits expire 5 days after sign-up, so try the full flow on a small list first.
The main difference is what happens after the recording. Loom’s sales page describes sharing Loom videos by link, via email, LinkedIn and more; EmailFlow OS takes your prospect list and sends one personalized video email to each recipient from your own Brevo account and domain.
Not as a permanent free plan. EmailFlow OS has a free trial: new accounts get 20 credits without a credit card, enough for up to 20 personalized videos of up to 2 minutes each, and the trial credits expire 5 days after sign-up. After that, sending needs a monthly plan or a credit top-up. Loom’s Starter plan costs $0 and, according to its pricing page, includes up to 25 videos per person with recordings of up to 5 minutes.
That depends on how you use it, because the two price differently. Loom charges per user per month ($18 on Business, $24 on Business + AI, billed monthly); EmailFlow OS charges per personalized video instead: 1 credit is one personalized video of up to 2 minutes, and the price of a credit falls with the size of the monthly plan.
Loom AI works on your recordings: titles, summaries, chapters and a drafted email to go with a video. In EmailFlow OS, AI writes an individual email for every recipient, using context from their website, your offer and your goal.
No. EmailFlow OS has no recorder of its own; you record your pitch with any tool and upload it. If you need a screen and camera recorder, Loom or a similar recorder still does that part, and EmailFlow OS handles personalization and sending.
The EmailFlow OS product page shows the full workflow, the pricing table and a sample email as your prospect receives it.
Choosing between several tools, the guide to video messaging tools for B2B cold email looks at whose domain signs DKIM and where the prospect list lives.
Why one recording becomes a version for each recipient, and which mail clients play video inline, is covered in personalized video messages for cold email.
