What is the best CRM

Since the majority of people are in sales and use free version of HubSpot, this article will be about growth hacks for salespeople who use Free Hubspot CRM.

#1 - Move to HubSpot from other CRMs easily

It's a real pain for people to move from one CRM to another. Sometimes it takes weeks, even months to get the job done. 😰

And the problem is not only with moving current data.

You have tons of integrations and leads that are coming and updating every day. If you don't update them in HubSpot CRM, you might end up in serious trouble.

This is a problem.

Now let me show you how to avoid it completely.

How to use this growth hack?

First of all, go to Zapier! It's a tool that connects 3d party software solutions and you don't have to possess any coding skills.

For example, if we want to move from Pipedrive to HubSpot CRM and always want to have updated deals in our HubSpot CRM, chose this:

Hubspot <> Pipedrive integration

Connect your Pipedrive account and come to the 2d step - add HubSpot action.

Hubspot CRM Zapier

Customize the data you want to connect:

When it's done - just run it!

#2 - Sync up your LinkedIn conversations

If you're in B2B, you're definitely talking to your clients and partners on LinkedIn. Great channel, right?

But it's a real pain to sync your LinkedIn messages with your CRM.

There is no "auto-bcc" feature on LinkedIn that can easily send your conversations to a CRM of your choice.

Except for one! LinkedHub.

How to use this growth hack?

You should download the tool called LinkedHub.

Once downloaded, it will ask you to connect your HubSpot account.

You can find your API key in Settings -> Integrations -> API. Copy it and put to LinkedHub settings.

When it’s done, go to LinkedIn. Find a person you want to add to HubSpot or update the conversation by clicking the Sync button.

Connect Hubspot with LinkedIn

‌‌When it’s done, you will see this person in HubSpot with all details.

#3 - Generate prospects with outbound lead gen

Wondering how to make amazing cold emails and add warm leads to HubSpot CRM?

And just to buy me some credibility as a cold emailer first...

  • 56% reply rate
  • 39 new sales meetings for a week

How to use this growth hack?

This is the best outbound hack, by far! At the same time, it's easy to implement it.

First, create an email campaign in lemlist.

Add your leads and prepare the message.

You can send your own email templates, but let me give an example of a template for growth and marketing agencies.

The idea of this email is to meet the person in real life.

I recorded a quick video and combined it with lemlist's dynamic landing page feature. This strategy is called personalized video thumbnail and it's superb.

Personalized video in cold email example

This unique feature of lemlist got me a 56% reply rate. Here's what you need to do to set it up.

Create a video and upload it to Youtube. If you want to show this video to leads in your campaign only and not have it on your channel, select “unlisted".

Copy the link of the video and add it in lemlist by clicking “Insert video button”.‌‌

Embed video in cold email

Customize your landing page with the prospect's logo, colors, and text personalization.

For example, if you write “Welcome {{firstName}}”, lemlist will automatically put the recipient’s first name.‌‌

lemlist personalization

Add your calendar below the text and video. For instance, put your Calendly in settings on the right side.

How to book more sales meetings with cold email

You can show a custom pop-up message (in chat) once the person finishes watching your video.

Cold email sequences Hubspot CRM

To do this, create an account at lemtalk and copy the “Your Application Id (appId)”.

So at the end of the video, your leads will see a pop-up like this:

Video personalization in cold outreach

‌‌The end result is a personalized email with this dynamic landing page, where lemlist automatically personalizes each part of it.

Here's how the final email looks like.

The first name and company logo are automatically updated, which is another awesome feature of lemlist.

For inspiration: Choose one of our inspirational cold email templates

Now it's time to stop sending emails to people once they book a meeting.

And here we'll need Zapier! The Zap will look like this:‌

Hubspot Calendly Integration

Go to Zapier and choose a trigger called "Invitee created in Calendly".

By doing this, Zapier will work for those who picked a slot on your Calendly link.

‌‌If you didn't use Calendly and Zapier together, you'll need to put an API key from Calendly to Zapier.

It's easy as 1,2,3. Just log in to Calendly and go to "Integrations":

Calendly API

Stop a campaign for this specific person (so he/she won't receive follow-ups since they booked a time):

To do that, we pick lemlist and "Stop emailing a Buddy-to-be in a campaign"

Define the fields "email" and "campaign" to exclude people.

It's super easy to do:

  1. Choose the email that came from Calendly
  2. Select the name of your lemlist campaigs

If you haven't connected Zapier and lemlist before, Zapier will ask you to connect your lemlist account.

In order to find your "login and password for Zapier", go to lemlist --> settings --> integrations --> scroll down to "Zapier".‌‌

Time to create new deals in HubSpot with those who booked a call.

#5 - Track proposals you send to prospects

Let's face it, you always send some materials like white-papers, presentations and so on. The more you work in B2B, the more you use these tactics.

But do your leads really read them? And if yes, what exactly do they read?

This is the info that definitely can help you find the right strategy.
