This is not a versus post because most teams in 2026 have the best performance running LinkedIn and email together and letting each do the part it is actually good at. But if you are deciding where to start or where to put your budget, the two channels behave very differently, and picking the right one is crucial for some early success and putting your business on solid feet. Everything in the post is based on the research conducted by us at Expandi on dozens of campaigns run within our platform.

Where email still wins

Email is the reach-and-detail channel. It scales cheaper than anything else, a domain runs under $10 a year and a decent sending setup is $30-100 a month, and from there the cost of reaching one more person is basically nothing. It also has room for formal assets: links, attachments, a longer explanation, and a formal follow-up - however, you HAVE to be careful with how you use these because some will heighten the risk of getting flagged.  The tradeoff is that it's easy to get buried under a pile and ignored. People get 100-200 emails a day, average cold open rates are around 27-28%, and reply rates hover near 4%, with good campaigns barely reaching above 10%. It also punishes impatience, since a new domain needs 3-4 weeks of warm-up before you send at volume, or you land in spam and just burn the domain.

Where LinkedIn wins

LinkedIn is the trust-and-targeting channel. You can filter down to the exact person by title, company, industry, and seniority. The message lands in an inbox that is not buried under fifty newsletters, and there is no spam folder to fall into. Response rates reflect that, with InMails replying in the 10-25% range, and a personalized message dramatically outperforming the same words sent cold over email. The ceiling is volume and cost, although there are some workarounds for volume, at least. LinkedIn caps an account at roughly 100 connection requests a week no matter what you do, but if you have a few SDRs, you can scale this up with each of their accounts. However, this is when the premium tier costs can add up, so it’s best to start evaluating the channel with one or two accounts and scale up if there’s traction. It should be treated as a scalpel, not a firehose.

Why both beats any single channel

The channels cover each other's weaknesses, and we've seen this hold across every team we've watched scale. This is actually one of the main reasons we added email automation to Expandi in addition to LinkedIn automation - the sales evolved over the years, and teams using both channels to complement each other vastly outperform the ones focused on a single channel. Being able to do that from a single place helps a lot because LinkedIn earns the trust and gets you recognized, and email carries the detailed case once they know who you are. Just as important, a second channel gives you a second door if or when the first closes. Someone who ignored a connection request will sometimes answer a short email that references it, and someone who opened an email but did not reply is a warm target for a LinkedIn note. Every extra relevant touch on a different channel raises the odds of a reply, as long as the touches are coordinated and not the same message fired twice.

How to sequence them

The order that works is trust first, detail second:

• Warm the lead on LinkedIn with a profile visit or a real comment on something they posted, before any ask.
• Send a connection request with a short, specific note, or send a request without a message if there’s nothing specific to reference. Wait a day or two before the first message so it does not read as a bot firing both at once.
• On accept, open a light conversation on LinkedIn, not a pitch.
• Move the detailed proposition to email, where a longer message belongs.
• If LinkedIn goes silent, use email as the follow-up door, and reference the LinkedIn touch so it connects.

Trigger each next step off what the lead actually did, not off a timer. And the moment they reply on either channel, pause the other sequence so you never talk over your own answer.

If you are selling B2B to a definable ICP and you can keep the two channels aware of each other, run both because that’s the absolutely best-performing approach. Lean email-only if you need raw reach at low cost and your list is large and loosely defined. In this case, it doesn’t make sense to pay the higher cost of LinkedIn without having a clear picture of who you’re targeting, why, and how you’re approaching them. On the other hand, if your market is narrow and relationship-driven, where getting to the right twenty people matters more than raw volume, and there’s a real risk of burning through the leads if you rely on sheer volume - go for LinkedIn.
