Short answer: UpLead tells you the price before you talk to anyone: $99 a month for 170 contacts, or $199 for 400, with no contract on monthly billing. Seamless.AI does not publish prices; you get a quote from sales, and in return its Pro licence comes with far more credits, 10,000 a month per user. Choose UpLead for a few hundred contacts a month bought on a card. Talk to Seamless.AI only if you need thousands of contacts a month per rep and are ready for a sales-led contract.
Three differences that decide it
1. How you buy. UpLead has a pricing page with numbers: Essentials at $99 a month ($74 billed yearly) and Plus at $199 ($149 yearly); only its Professional team plan is quoted. Seamless.AI's pricing page is an inquiry form, and its own blog says there is no fixed rate: packages are tailored by sales.
2. How many credits you get. UpLead gives 170 credits a month on Essentials and 400 on Plus; extra credits cost $0.60 and $0.50. Seamless.AI's free account has 50 credits that never refill, Basic has 250 a month, and Pro has 10,000 a month per user.
3. What a credit buys. On UpLead one credit unlocks one contact for download or CRM export, with the verified email and phone numbers it has. On Seamless.AI a credit pays for one contact found through search, enrichment or its Autopilot feature, and its AI writing assistant uses a fifth of a credit per message.

Doing the maths without a Seamless.AI price
UpLead's cost per contact is easy: about $0.58 on Essentials monthly, $0.50 on Plus monthly and about $0.37 on Plus billed yearly ($149 × 12 ÷ 4,800). For Seamless.AI you need the quote first. A useful way to read it: divide the yearly price you are offered by 120,000 (10,000 credits × 12 months) per Pro user. If the result is above UpLead's $0.37 to $0.50, UpLead is cheaper for the volume you actually use; if you will not use most of the 10,000 credits each month, the comparison tips further towards UpLead.
Which one for which buyer
- Founder or single SDR, under 400 contacts a month: UpLead Essentials or Plus. No call, no contract, cancel when you stop.
- A team that needs thousands of contacts per rep every month: get a Seamless.AI Pro quote and compare it with UpLead Professional.
- Anyone unsure about data quality in their niche: use both free allowances on the same 20 target accounts and count the working emails and direct numbers.
If your target accounts are already in a LinkedIn or Sales Navigator search, a third route is to export that search instead of buying traditional database access. Specialized LinkedIn B2B data extractors allow you to export searches past the 2,500 results Sales Navigator limit, finding verified work emails and phone numbers directly from profiles. Comparing alternative extraction workflows can often yield higher contact volumes for specialized niche targeting.
