Are you only using LinkedIn, Email or maybe cold calls for your sales outreach?

Or maybe you’re already using multiple channels, but not getting the results you hoped for…

The fact is, Multichannel outreach WILL get you more leads and sales opportunities

But it’s important that you do it the right way.

I’ve seen founders, SDRs and sales teams get much better results after they broadened their outreach.

And I can’t wait for you to reach the same results by the end of this blog.

We’ll go over,

That’s right, you’re gonna have all the tools in your bag to throw your own net into the ocean of prospects.

So stick around, and let’s get rolling!

A baby panda rolling.

What is Multichannel Outreach?

Multichannel outreach means reaching out to prospects using different channels.

You don’t restrict yourself to just LinkedIn, or just Email. Instead, you can run outreach campaigns on both.

This way, you’ll grab the attention of both people who primarily use LinkedIn, or stick to emails.

You’ll be like the extrovert in the party, talking to everyone from any crowd!

Using many channels means much better chances of a response, eventually leading to conversion.

All the big businesses do it, and that’s because it brings results.

Why should you do Multichannel outreach?

If you’ve been doing single-channel outreach and need some convincing, I’ve broken it down into some key points.

First off,

1. You’re not dependent on one channel

If you’re just doing LinkedIn outreach, prospects who only use Email are completely out of your reach.

On the other hand, if you don’t have the emails of your prospects, you won’t be able to do any email outreach.

(Although that’s not a problem with SalesRobot’s email enrichment features)

Either way, it would be much more effective to reach out on all possible channels because

More number of  channels -> More sales engagement -> $$

2. You’ll have a backup plan

Imagine you’re primarily doing only LinkedIn outreach, and you find one day that your account has been restricted.

It happens when you’re not using trustworthy automation tools.

Now what if your strategy was only LinkedIn outreach?

Your complete outreach process would come to a standstill. Yikes!

Instead, you can focus on other channels during the downtime and still continue growing.

Make sure you never have a single point of failure, keep other channels to fall back on.

3. You give the prospect more chances to reply

We’ve all been ghosted before, it’s a horrible feeling...

If you’re not getting a response on a single channel after a follow-up or two, it’s unlikely you will in the future.

But that’s not the end of it.

You can try again with the same prospect on a different channel like it’s a fresh conversation. 😉

This brings another opportunity for the prospect to reply and they may even appreciate the effort you’ve taken.

Make sure you’re not being spammy though.

Multiple channels provide the prospect with more opportunities to reply which provides better results over time.

It’s simple maths.

4. People have different preferences

Everyone has a preferred communication channel, even you probably do.

LinkedIn generally has a 14x higher response rate than Email, so I like it more.

But some people will likely respond to an email more than check their LinkedIn inbox.

Some people may not like either and prefer to talk on a cold call.

The only way you find their preferred means of communication is by doing multichannel outreach.

5. You may discover better channels

If you’ve always stuck to one or two channels, you’ve probably already got a solid process running.

Exploring with new channels may open up doors you didn’t even realise existed.

There are several advantages and disadvantages with each channel as well as tools that work with it.

Only by experimenting will you find out what works the best and gives the highest ROI in your industry.

In other words, get out of your comfort zone.

And if you’re wondering what channels to explore first…

5 Most effective sales outreach channels

I know what you’re thinking, everybody on the internet and their grandmother is asking you to  “do multichannel outreach”,

But what good is this advice if you’re not even sure about the channels you should outreach from?!

No worries, I’ll let you in on the most effective ones throughout my years of sales experience.

1. LinkedIn InMails

Outreach campaigns on LinkedIn have proven 14x higher response rates than with emails.

However, there’s also differences between LinkedIn InMail outreach and LinkedIn Message outreach.

You can send InMails to anyone on LinkedIn even if they aren’t connected to you, unlike Messages.

It’s a great feature to target high-profile prospects, do cold outreach and also for networking with new people.

This makes it one of the best channels to include in your outreach strategy.

However, they’re not free and cost InMail credits. (Unless they’re an Open Profile, which SalesRobot automatically tracks)

2. LinkedIn Messages

LinkedIn Messages are free and the most direct way of communication on the platform.

The catch is that you can only send it to people you’re connected with. So it’s a two-step process.

If you're doing outreach manually, that means you have to first send personalized connection requests to all your prospects.

Then wait for them to accept, and then send a LinkedIn message.

Of course, this can easily be automated with SalesRobot which will do that for you alongside personalized messages and scheduled follow-ups.

It’s also important to draft your LinkedIn messages properly, we’ve got some helpful templates that will definitely boost your engagement.

3. Email

Email provides the best response rates after LinkedIn, and doesn’t have limits or pricing barriers either.

One challenge is avoiding spam detection, which good email automation tools help a lot with.

When’s the last time you looked at an email in your spam folder? I know I haven’t.

If you’re not using a tool, you’ll need to personalize your emails, draft them each individually and also track follow-ups.

Another issue is even finding the email address of some prospects that may only have LinkedIn or Facebook.

I’ve got a neat solution for that though,

SalesRobot’s email enrichment tool is something that comes in handy there, since it can find email addresses and phone numbers of your prospects from its extensive database.

4. Cold calls

In the world of digital messaging and emails, cold calls are slowly trending out of fashion.

However, when LinkedIn messaging and emails don’t get a reply, it might be a decent try to give them a call.

This can provide a direct line of contact and real-time communication with your prospect, putting your sales skills to the test.

You can also get their immediate response and can mark them down as interested or not.

It’s good to make sure that you only call them after they ignore your messages, just so you don’t come off as a complete stranger.

5. Twitter / X

When you think of B2B sales or professional platforms, you generally don’t think of X.

But there is a large B2B audience on the platform, consistently posting and engaging with the latest trends.

You could also post about your company or engage with potential prospects on X.

Although unconventional, it may just work out anyway!

These are all the channels you should keep in mind, but how do you start doing your multichannel outreach on these?

You could definitely manually send out messages on different channels.

Or you could make life MUCH easier.

Regardless, we’ll still look at how to create your overall strategy.

How to effectively do Multichannel outreach?

We’ve covered all the main components of a good multichannel outreach strategy, but how do you put them together?

First off,

1. Focus on mainly two or three channels

Although we’ve covered 5 fantastic channels that have a great audience of prospects.

But that doesn’t mean you should run campaigns on all of them. That will just stretch you thin.

It’s best to focus your efforts on any two or three channels that work best for you and have the best returns.

I’d suggest LinkedIn and Email since that’s where 95% of your prospects will be.

2. Personalize your messages

Regardless of the channel of choice, you still need to get a response.

Personalizing your message to each prospect will indulge them much better and help you stand out.

You could do this manually through research, time and effort. Or you can take the help of SalesRobot which will do it for you.

3. Analyze metrics and adapt

A business is all about adapting, learning and growing from your campaigns.

Make sure you keep track of all important metrics like open rates, response rates, click through rates and more.

It’s much easier with a tool… you already know which one.

SalesRobot also provides A/B testing so that you can compare message sequences and pick the best performing ones.

Conclusion

In the end, multichannel outreach is definitely a must if you really want to get more leads.

There’s so many potential prospects out there who you’ll never contact with single-channel outreach.

The five best channels to consider are,

  • LinkedIn InMails
  • LinkedIn Messages
  • Emails
  • Cold calls
  • Twitter / X

And if you don’t want to spend a ton of time working all of these channels manually…

There are fantastic tools that will automate the entire thing for you.

Namely,

  • SalesRobot, if you want complete LinkedIn + Email automation with hyper-personalization, follow-ups, enrichment and more
  • Klenty, if you want 5+ channels with an AI SDR and an in-built dialer
