Queue-it helps in high-demand and limited-supply situationsโlike sneaker releases, ticket on-sales, or government registrationsโthat can easily overwhelm a website or app. In these high-demand situations, online visitors are redirected to a customizable waiting room and then throttled back to the website or app. In the case of scheduled sales or registrations, organizations can create a scheduled waiting room that holds early visitors on a countdown page and randomizes them just like a raffle once the sale or registration begins, giving everyone an equal chance. Later visitors are then added to the end of the line on a first-come, first-served basis. Queue-it's virtual waiting room can also guard against traffic overload 24/7, working as a safety net by constantly monitoring traffic inflow and only activating the waiting room when traffic exceeds the configured thresholds. By controlling online traffic, Queue-it's virtual waiting room lets organizations control their online experience. They capture sales, deliver seamless user experiences, ensure fairness, and protect brand reputation.
Apollo.io Queue-itWe use Apollo with our Sales and BDR team to manage our cold outreach. The strength of the platform is the sequences and cadences that you can set up. Compared to other tools we have used in the past like Salesloft the UI is much easier to navigate. The main limitation is that the quality of data isn't as vast and often I can find prospects on Linkedin but not in Apollo.

Personal email domains destroy this. Clearbit's Enrichment API returns a null company when it hits gmail.com. Apollo routes personal domains straight to a consumer bucket and skips B2B fields entirely. Even PDL's /person/enrich endpoint โ the most permissive of the major providers โ gives you around 32% hit rate on Gmail addresses versus 74% on corporate domains. I measured this across 6,200 signups for a... - Source: dev.to / about 2 months ago
A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did โ the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / about 2 months ago
One thing comparison guides consistently get wrong: Clay is not an enrichment API. It's a waterfall orchestration tool that calls People Data Labs, Apollo, Clearbit, and others in sequence for you. It's useful, but it adds 2โ8 seconds of latency per row in my runs and costs more per match than going direct. For a CRM webhook flow where you need sub-second enrichment calls, Clay is the wrong layer to hit first. - Source: dev.to / 2 months ago
Last year I ran the same LinkedIn Sales Navigator export through three enrichment APIs. Apollo matched 61% of the emails. Hunter.io matched 54%. An OSINT-first pipeline I'd built in n8n โ pulling from public sources before hitting any paid API โ matched 79% and cost roughly $0.003 per contact. The delta wasn't magic. It was sequence. - Source: dev.to / 3 months ago
Despite having its LinkedIn Page removed in 2025, Apollo remains a functional enrichment and outreach platform with 275M+ contacts. The free tier includes 10,000 credits and the $49/month basic plan is the cheapest entry point for a combined enrichment-plus-sequencing workflow. Apollo's data collection methods have attracted LinkedIn's attention, but the product continues to operate. The risk I'd assign it:... - Source: dev.to / 3 months ago
There's a whole business for bad performing websites that need to limit visitors! https://queue-it.com/. - Source: Hacker News / about 2 years ago
Hello, I've been frequently archivng the Bungie Store as part of a wiki project for a few years now, but recently the website began acting strangle. The store has a queue system which it usually only deploys once a year (using the service Queue-It) to combat latency and bots. This has never been an issue when backing up the site using Wayback Machine before, as recently as October 4th, 2023. However, earlier this... Source: over 2 years ago

Not that I donโt think it can be done, but the waiting room tech probably doesnโt want to support it. https://queue-it.com/ is where we were all sent. Source: over 3 years ago
