Doctor Email List vs LakeB2B
LakeB2B is priced by quote; Doctor Email List is one fixed price per specialty file, paid once, built from the public CMS file. Pick LakeB2B if you want a vendor that prints a national count, an email count and an update date on every specialty page, and sells data for other countries too. Pick ours if you want the price on the page before you talk to anyone, and one CSV you pay for once.
We make Doctor Email List, so we are on both sides of this page. Everything about LakeB2B is what it publishes on its own site, read on Oct 6, 2026, and each cell links to the page it came from. We did not buy a list from LakeB2B.

When LakeB2B is the better pick
- You want a vendor that prints a national count, an email count and an update date on every specialty page, and sells data for other countries too.
- You want the email column already built and a free sample of contacts before you talk price.
- You buy on an annual plan or credits, or want a one-off custom list, and are fine requesting a quote.
When Doctor Email List is the better pick
- You want the price on the page before you talk to anyone, and one CSV you pay for once.
- You want every row tied to an NPI you can look up in the federal registry.
- You want written bounce-refund terms. We found none on the LakeB2B pages we read.
Where we are weaker: coverage stops at physicians enrolled in Medicare, and the email column is built for your file after you order, so check the data page for what a row holds before you buy.
What we could not check
We did not buy a LakeB2B list, so we can't say how many of its emails are good. Its dermatology page prints a national count in its header and a much smaller global count in its text (both on the page we read on the date above), which is why we ask any seller what one row is before you pay.
