Multichannel outreach

People don't read all their channels with the same attention. Some decision-makers answer on LinkedIn and let their inbox pile up, others do the opposite, others only react on their phone. Multichannel outreach starts from that observation: a single channel leaves part of your target out.

The word is often misunderstood. Sending the same message on three channels on the same day is noise. A real multichannel sequence decides which channel goes first, when to switch channels and, above all, when everything stops.

People sometimes call it omnichannel when the history is shared across every channel, so that each message takes the previous ones into account wherever they were sent.

Start with one main channel, the one where your target is active and where you can personalize the most. In B2B that is often LinkedIn, because the profile and the activity give you material for a precise first message.

Then add a second channel for prospects who stayed silent through the first sequence, and only for those worth the effort. A call or WhatsApp message to someone who never gave you their number can easily feel intrusive: keep that channel for numbers obtained in a clear way.

Decide when you switch. Moving to the second channel too early undercuts the first: LinkedIn replies come slowly, and a prospect who was about to answer next week gets a message somewhere else in the meantime. Waiting for the main sequence to finish gives the first channel its chance.

Finally, set the stop rule, the most important one of all. As soon as the person replies anywhere, the other channels go quiet. And a no on one channel counts as a no on every channel.

Measure each channel on its own, then the whole sequence. The useful question: how many replies and meetings does the second channel add compared with the same sequence on a single channel?

The clean way to answer it is a control group. Some prospects stay on one channel, the others get the full sequence. Without that group, you risk crediting the second channel with replies that would have arrived anyway. LinkedIn replies are slow: in the MimikFlow 2026 Observatory, 15.2% of them came after the first week.

Watch the negative signals too: stop requests, unsubscribes, reports. A channel that adds three replies and ten complaints costs more than it brings in.

Sending everything at once. A prospect who gets an invitation, an email and a call within the same hour feels hunted, and they are right.

Running tools that don't talk to each other. If your email tool doesn't know the person replied on LinkedIn, they'll get an absurd follow-up the next day.

Using contact details found who knows where. A mobile number bought from a database is a legal problem and spoils the relationship before the first word.

Adding channels to make up for a bad target. If the target is wrong, three channels just make three times as many annoyed people.

MimikFlow treats WhatsApp as a second channel on the same prospects. Both channels share the conversation context and stop following up as soon as the prospect replies, wherever they reply.

The platform never searches for phone numbers automatically. WhatsApp only comes in if the prospect wrote to you through your link, gave you their number, is already among your known and authorised contacts, or belongs to a list you imported with the Reactivation plan. The "Back up LinkedIn" use then schedules a WhatsApp relay for a priority prospect who stayed silent on LinkedIn.

On the LinkedIn side nothing changes: invitation, first message, follow-ups. The WhatsApp relay only starts for the prospects concerned, and you choose its uses and sending hours before switching it on.
