Lead411 Alternatives With Intent Data and Contacts: What to Compare Before You Switch

If your problem with Lead411 is the email and phone data, not the intent data, compare UpLead and Cognism on the same test list, and also price the option of keeping Lead411 and checking emails before they're sent. Intent data almost always sits on the top, custom-priced tier, so the real comparison is a sales call. Bring numbers from your own sends.

The question came up on r/gtmengineering: a team about eight months into Lead411 said deliverable emails had fallen from roughly three in four to closer to six in ten, mobile numbers rarely connected, and the intent signals sometimes pointed at companies that had already bought from a competitor. They wanted fresh intent and accurate contacts in one tool. Here's what the published terms say.

Lead411's published plans

From Lead411's pricing page (read 3 November 2026):

Plan	Price	Exports	Intent data
Pilot Light	$0 for 7 days	50	Not listed
Spark (monthly)	$49/month	1,000 a month	Not listed
Ignite (monthly)	From $150/month	1,000+ a month, API	Not listed
Spark (annual)	$490/year	12,000 a year	Included
Ignite (annual)	$1,500/year	Flexible	Add-on
Blaze	Custom	"Unlimited Exports / Year" (Lead411's wording)	Optional

The page says unused exports roll over, technographic search and verified emails and direct dials are included, and emails are "re-verified every 3-6 months". It doesn't publish a bounce credit policy.

UpLead and Cognism on the same points

	UpLead	Cognism
Public prices	Yes, below the top tier	No; quote only
Entry plan	Essentials $99/month (170 credits), or $74/month billed annually	Standard (5 seats)
Intent data	Buyer intent on Professional only (custom)	Bombora Company Surge on Pro; up to 12 topics
Technographics	Plus and Professional	"Technology usage" listed; tier not clear
Credit model	One credit = one contact (email and mobile)	One credit per revealed contact; re-viewing is free
Accuracy claim	"data accuracy rate of 95%"	Not stated as a number on the page
Bounce credit policy	Not on the pricing page	Not on the pricing page

Sources: UpLead pricing and Cognism pricing, both read 3 November 2026. We haven't tested either vendor's data; the table is what their pages say.

A note on accuracy claims: vendors measure them differently, on their own samples, at their own time. A 95% figure on one page and none on another tells you nothing about how either performs on your target accounts. Our post on questions to ask a B2B data vendor lists what to ask about how a number was measured.

The split-stack option

The Reddit team liked Lead411's technographics and contract-timing signals. If that's true for you too, there's a cheaper path than migrating everything:

1. Keep the data vendor for intent and technographics.
2. Check exported emails before they go into a sequence, so the bounces stop landing on your domains.
3. Use a separate, cheaper source for the contacts the vendor can't find.

This doesn't fix mobile numbers, which are the hardest data to keep fresh anywhere. It does separate the two problems: signal quality, which is a vendor decision, and email deliverability, which you can control on every export. Our guide to finding work emails for a large lead list covers step 3.

Test before you switch

Don't decide on a demo. Run the same test on each option:

1. Pick 300 target accounts you know well, including some that recently bought.
2. Pull contacts from each trial for the same accounts and titles.
3. Check the emails at /verify and record valid, risky and invalid per vendor. Use the email list sampler if you want a random sample from a bigger pull.
4. Check the intent against what you know: does it flag the accounts that recently bought from a competitor as "surging"?
5. Dial 20 mobiles per vendor and count connects.

Three hundred rows is enough to see a large gap; it isn't enough to separate two vendors a few points apart. Our post on lead data quality dropping before renewal shows how to put a range around a bounce rate, so you don't argue over noise.

Ask these at renewal or signup

• Is there a credit refund for bounced emails, and how is a bounce proven? Our post on lead data bounce credit refunds shows what other vendors offer.
• How old is the last verification on the contacts I'm exporting?
• Which intent provider is it, how many topics, and how often does it refresh?
• Is intent included in my tier, or an add-on?

Where SimpleVerifier fits

SimpleVerifier isn't a data vendor and doesn't sell intent data or contacts. It checks the emails you export from any of them before you send. The first 100 checks are free with a Google sign-in on the verify page. Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off, and one-time packs of 10,000 checks for $15 never expire. See pricing.
