How to send multiple emails in gmail at once with follow-ups

Updated: Apr 8

You can even personalize your emails for everyone and send them with a single click.

One of the main concerns that we have from our clients, is that some of them can't handle the email volume to send personalized emails promoting their services to several emails fast enough, and this is because nobody can't be manually sending emails all day, or you couldn't run your business at all.

This is where lots of tools and resources can make our life easier, making it possible to automate processes, save time, and work smarter and faster than before.

If you use Gmail as your email provider, you can reply to all emails from a spreadsheet using Gmass.

To add Gmass to your Gmail account for free to test the following guide CLICK HERE and click “Add to Gmail”.

After linking Gmass with your Gmail account, you can start using it to send mass emails as individual emails, and you can even personalize them as you want.

To start sending emails in bulk to your leads, you can prepare a Google Spreadsheet with different fields to add your Leads and their information. (Name, Username, Email, and such)

Save your Google Spreadsheet with any name that you want, and go back to Gmail.

IMPORTANT: Gmass will connect to the Spreadsheets of the same Google account that you will be using to send the emails. You can not connect to spreadsheets from other google accounts.

Now that you are back in Gmail, click the Spreadsheet icon:

If you don't see it in the top bar, re-start your navigator or connect Gmass again.

This may not work from an Incognito Window.

Now you can choose the previously saved Google Spreadsheet from the dropdown menu and click CONNECT TO SPREADSHEET.

You will see a new draft of an email, and also you will see that all of the addresses from the row “Email” are loaded in the “To:” field as a code.

You will also see a Gmass red button instead of a Gmail blue button. Keep in mind that you need to send this draft using the Gmass red button.

In the previous image, you can see the draft with the emails loaded in the “To:” field as a code.

In this case, the number of emails is 0, but that number will represent how many emails were placed in the “To:” field.

In this draft, you will be able to write your email and even personalize it with the fields available in your spreadsheets.

For example, you could use the receiver's {Username} or {Name} to address their specific Social Profile Usernames and Names in your emails.

If you get creative here, you can really make a powerful strategy out of this simple tool.

Imagine if you would take a look at each of their profiles, or their website, and add a field in the spreadsheet named something like “Moreinfo” and write a short personalized paragraph regarding their specific business and how it can befit from your specific service.

Now, when you are writing the draft email, choose a part where you think this paragraph would fit perfectly, and simply add the code {Moreinfo}. The specific paragraph for the specific receiver will be displayed in the email.

You can test all of these things in a test email sent to you. But if you do get creative, this can be very powerful, as you can reach out to hundreds (if not thousands) of emails, in a personalized way with a single click, after setting up everything.

To set up your Gmass campaign we need to take a look at the Settings.

For this, click the arrow next to the word “Gmass”. This will open the campaign's settings.


There are 3 important sections for your campaign:

  1. Personalize: If you click here, you will see the fields that you can personalize in the email, matching the rows that can be found on your Google Spreadsheet, with the specific name that you have given to them. This works by selecting a field like “Username” in your settings and clicking it. Now, if you go back to your draft, you can paste (CTRL + V) the code into your email, which is simply {Username}. All codes are generated with the row's name between “{}”.

  2. Send with: Gmass provides the option of connecting to an external SMTP relay service, which are external services developed for email systems that need to be set-up. If you don't use SMTP external services, make sure that Gmail is selected here or your campaign will not be launched. This simply means that the emails will be sent using your Gmail limits, just like you were doing before (if you didn't use SMTP / See more of Gmail limits at the bottom of this article).

  3. Auto follow-up: Now you can set-up an auto follow-up to reach out to your leads that didn't reply back to your first email. Set-up a date (+3 days is recommended) and ask them if they had the time to read your information. If you get creative here (one more time) you can offer a special discount or a special offer to your leads, and maybe ask them a specific question about their business, to incentive them to reply to you. Take a look at our article "The importance of follow-ups and discounts" for ideas on this.

You can also schedule your campaign to be sent whenever you want, and you can open Advanced settings to skip emails previously contacted, or to name your campaign.

When you have finished setting up your preferences you can go back to the draft, double-check everything, and you are good to go!

To send your campaign, remember to click the red Gmass button, and your campaign will be sent accordingly to your preferences, as individual emails.

The follow-up sequence will be sent after the number of days previously selected by you in the settings.


There are some limitations and risks to take into consideration when using mass email tools and resources, and you need to consider them if you want to perform a good practice.

Gmass in its free version, allows you to send 50 emails per day.

Even so, in the free version, this is a super helpful tool, as you can contact 50 emails individually with a simple click each day.

Also, keep in consideration Gmail's limitations, as you are only able to send up to 500 emails per day with a personal account, and up to 2000 with a business account, but it's not recommended to overload your Gmail's limits as this will easily block you from sending emails for some time and you will not be able to reply if you get an email.


Even with Gmail allowing you to send 500 emails per day with a personal account or 2000 with a business account, be careful here, because hitting the limits of Gmail for a long time will make your activity look suspicious, so if you don't have experience in cold email outreach, spam laws, and good email practices, I don't recommend to use your Gmail sending limits for anything else than for contacting people who have already given permission for you to reach out to them, or to perform a manual Cold Email strategy with low numbers but high-quality personalized emails.

Mistakes in these practices will harm your email account and your deliverability.

The Auto-Follow up is only available in the paid Gmass version, as well as the chance to send +50 emails per day using the tool. You can send up to 50 emails per day with the free version. Perfect to test it out with a manual Cold Email strategy, or to contact your warm leads if you are already generating them and handling a big volume of emails.

To connect Gmass to your account CLICK HERE.

We hope you can leverage this tool to make the best out of it and scale your business by having the chance to approach a lot of sales prospects in a personalized way with a simple click!
