How are you handling list enrichment at scale?

Look, I'm scaling outbound across multiple domains and the enrichment step is the biggest pain in the arse right now. Not the sequencing, not inbox setup - it's the data layer. Getting clean emails, some phone numbers, filtering out bad matches before anything hits a campaign.

The credit-based model is a disaster when usage fluctuates month to month. One month I need 10k enriched, next month 40k. Fixed credit tiers make no sense for that.

What I've found is you have to split the workflow. Clean the raw list first - remove obvious junk, invalid formats, catch-all risks. Then enrich only the contacts that survive that first pass. Running everything through one tool at once is just burning credits on garbage.

But here's the thing - the cheap "flat rate" cleaners I tried looked fine on paper, then the bounce rate was horrific. That scared me more than the price.

I now use two different enrichment layers. They pull from different data sources, so I get better coverage. One might catch emails the other misses, especially for smaller B2B companies.

Main criteria: decent match rate, valid work emails, some phone coverage, proper catch-all handling, and no annual lock-in.

How are you guys structuring this? One tool or layered? Not burning cash on bad contacts is the goal.

Oh, you sweet summer child. Yeah, throwing everything into a credit-based tool and hoping for the best is a fast track to burning budget faster than a mediocre influencer campaign.

We split it into layers too-nuke the obvious garbage first, then only bother enriching the contacts that actually survive the initial scrub. Doing it all in one go with a single platform is hilariously wasteful when half the list is still borderline unusable afterwards. Costs stay in check, and you don't end up paying to enrich dead emails.

I ran a primary audience data source for about four months and saw my match rates on niche beauty SMB lists creep past 8% before I realised the issue wasn't the targeting setup. Added a second enrichment pass from a different data partner to fill the gaps the first one missed, then ran everything through a verification tool on whatever came back. Match rates dropped back under 2%. Independent agencies in this space are rough because the big data platforms just don't index those niche segments well, so you almost always need a second source.

Don't bother with fixed credit providers-go unlimited instead. My company made that switch and it's been a game changer for scaling up. Hope that's okay to share here.

Oh, bless - another "how do you enrich?" thread. I feel like we have this chat every six months and the answers are always the same mix of "we built our own" (you poor thing) and "we just pray and refresh the CSV."

We've been using syncgtm for the enrichment side. Their waterfall approach for emails and phone numbers actually works, which is rare in a sea of providers that promise the moon and deliver a soggy napkin. Coverage is higher than most, and it doesn't cost the GDP of a small nation. Shocking, I know.

What tool are you using for that initial scrub though? So many of those "affordable" services look pristine on paper, but the moment you hit send, you get this ghastly bounce rate that tanks your sender reputation and muddies your brand's placement in inboxes. That part haunts me far more than the price tag.

We do exactly the same-scrub first, enrich later. It's the only way that makes financial sense unless you enjoy setting money on fire. Running everything through one tool is just burning credits on garbage contacts that should never have made it past the first pass anyway.

What we've found is that using two separate tools actually gives way better coverage because they pull from different data sources. One will find emails the other completely misses, especially for smaller companies where the data landscape is more fragmented. It's not the fastest approach, but it's the only one that doesn't make me want to throw my laptop out the window.

I'd treat the first pass as a filter, not a full enrichment run. strip out obvious garbage first - bad domains, duplicates, role-based aliases, anything that clearly doesn't match your ICP. Otherwise you're paying to enrich contacts you were never going to reach anyway. After that, enrich only what survives.

for enrichment specifically, I'd test QuickEnrich on a small sample CSV. It's more of a lightweight email/phone layer than a workflow platform, so it avoids the credit-limit headache while you validate output quality. Don't move everything at once - run a sample, compare usable rates against your current method, and scale from there.
