Apollo.io RemNoteWe 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.
We all love the idea of building a "second brain". RemNote has become increasingly popular since the start of 2020. Why? *Because it combines studying with Knowledge Management in a way that hasn't been seen before. *
If you are searching for a rather learning-related tool for โconnected thinkingโ, RemNote is the way to go. In RemNote, you can create spaced repetition flashcards while taking notes with the outlining feature. This is beneficial because the order of your notes will always keep tidied up - You will always have an overview.
Additionally, RemNote adds new features every month. You can use it for Project Management, Note-Taking, or even journaling.
Based on our record, Apollo.io should be more popular than RemNote. It has been mentiond 69 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
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 / 3 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
Has anybody used remnote.com for IGCSE? If so, how do you use it to make notes/revise? Source: about 3 years ago
Flashcards/spaced repetition is a great way to get familiar with concepts and terms for memorization based subjects. Some apps like Remnote and Quizlet are great since they make you practice concepts you're less familiar with more often and concepts you're more familiar with more often. You could open it up any time you're idle like on the bus too. It'd either require you to make your own flashcards first or get... Source: over 3 years ago
