/// Head to head
Hound vs Instantly
Instantly is a sending machine: unlimited inboxes, warm-up infrastructure, and AI campaign assembly at aggressive prices — with a 450M-contact static database attached. Hound is a discovery engine that finds the leads Instantly's database can't see: local UK businesses, fresh incorporations, people asking for help on Reddit today. They compose: many users hunt with Hound and send with Instantly. If you only pick one and your bottleneck is sending volume, pick Instantly; if your bottleneck is knowing who to contact, that's Hound.
Choose Instantly if
- ·Your bottleneck is sending: you need inbox rotation, warm-up, and campaign automation at volume
- ·You already have lead lists and want the delivery infrastructure
- ·US-centric B2B contacts from a large static database are good enough targeting
Choose Hound if
- ·Your bottleneck is discovery: you don't know who to contact yet
- ·You sell to UK and local businesses that aren't in any contact database
- ·You want intent — people publicly asking for your service — not just firmographic filters
- ·You want to stay in control of sending rather than automate it (or pipe Hound's exports into Instantly)

Common questions
Can I use Hound and Instantly together?
Yes, and it's a natural split: Hound finds and qualifies the leads (live discovery, scoring, verified emails, drafted openers), you export the list and let Instantly handle sending infrastructure. Hound deliberately doesn't build sending; Instantly's database deliberately isn't a live discovery engine. The tools don't overlap where each is strong.
What does Instantly do better than Hound?
Everything about sending. Warm-up, inbox rotation, campaign sequencing, reply detection, deliverability tooling at scale — that's Instantly's moat and Hound has none of it by design. If you already know exactly who to email, Instantly alone may be all you need.
Is Instantly's leads database the same as Hound's live search?
No. Instantly bundles a static database of ~450M contacts refreshed periodically — the same architecture as every contact database, with the same decay. Hound stores no leads at all: each hunt is a fresh search of live sources at the moment you run it, which is why it can find businesses registered this week or a Reddit post from this morning.

Run one hunt. Every lead found live, scored, and timestamped — nothing served from a database.
