There are many reasons why marketers choose bulk emails, such as:

Pros of Bulk Emailing

The most lucrative benefit of bulk email is that it reaches a large number of people at the same time. So, mass email campaigns are especially invaluable during festive seasons or discount sales as they reach as many inboxes as possible. 

Not only it saves time and manual effort, but it also saves money.

Send Bulk Emails from Gmail in 5 Easy Steps

As per Litmus Email Analytics, 27% of all email users use Gmail as their primary email service provider as of August 2020. Although Gmail is more suitable for private messaging than commercial usage, you can send bulk emails through it. 

Let's check out how you can send mass emails through Gmail:

Step 1: Add a Mail Merge Plugin

Mail merge services help you send personalized bulk emails by optimizing the content with personal data such as the prospect's first name, business address, and email address. 

So, the first step towards ending bulk emails from Gmail is to install a mail merge extension to Google Workspace. Yet Another Mail Merge (YAMM), Mailmeteor, or GMass for Gmail–we recommend choosing any mail merge extensions. 

Once you are done, allow the platform to access your mailing list. 

Step 2: Curate an Email List

The second step is creating a clean email list of the prospects you want to send emails. Keeping a clean list with your prospects' names and email addresses is crucial. 

Adding a prospect's first name to the email makes them feel valued, which is very important for your bulk email campaign. It will not only personalize the campaign but also improve email open rates

Step 3: Write a Message

Writing compelling email content is an essential part of sending bulk emails. It takes skillful copywriting and compliance with Internet laws (CAN-SPAM act and GDPR). 

Always address your prospect by their first name and start with a warm greeting. Personalize your content by congratulating them on their recent personal/professional achievement. 

Now, optimize the content you intend to customize in the email blast. Use keywords to automate the filling-up process by adding keywords like this: "{{name}}." 

Here's a checklist for creating bulk email content: 

  • Intriguing subject line
  • Proper links`
  • Short and crisp email body
  • No spam triggers 
  • CTA
  • Add a plain text version

Writing compelling bulk mail takes excellent copywriting & personalization skills and an in-depth understanding of the prospects' needs.

Step 4: Create Subscribers' List

Create a new Google Sheet or upload an existing one to organize your contacts. Open Gmail from the browser and click on the Google Apps button to open Google Drive. 

Create a new Sheet or upload an existing .csv file or Excel Spreadsheet if you have already created your subscribers' list. Make sure you add clear headings for each column describing the type of information. 

And remember that one column should contain a mailing list. 

Step 5: Launch Bulk Email

Finally, add the sender name and business address, so your clients know who you are, and start mail merge from the extension tab. 

Now your mass mail is ready to get launched. Remember that you can only send 500 mails in a day from Gmail, so if you have subscribers of more than 500, automate sending mail for the next day. 

You can also schedule your mails to be sent later.

A mail marketing tool is the best bet to step up your marketing game. You can choose from several excellent tools like Sendinblue, Constant Contact, GetResponse, or HubSpot. 

Tips to Avoid the Spam Folder: Best Practices for Sending Bulk Mails

1. Keep Your Mail List Clean

The first rule for keeping an authentic mailing list is not to buy lists from third-party platforms. Instead, build and nurture your mailing list organically. 

Use Lead Generation Tool

Leading mail marketing tools such as HubSpot, Constant Contact,, Optimonster, Sendinblue, etc., offer multi-channel (LinkedIn, Facebook, WhatsApp, Twitter, etc.) lead generation features. 

These tools help you generate authentic, relevant, and industry-specific leads and verify them for improved deliverability rates. 

It will help reach the desired audience with your campaigns and keep you away from the spam folder.

Ask for Consent: Enable Double Opt-in

Neither anyone nor spam folders like receiving unsolicited mail. The key to maintaining a good domain reputation and building goodwill for your business is asking your subscribers for their consent. 

Activate the double opt-in feature on sign-up forms for acquiring prospective mail addresses. It will ensure that you collect the mail addresses of people who want to receive your mail. 

Beware of Spam Traps

Returning to the first point we've mentioned, don't buy mail lists from third-party platforms, as they will reduce your deliverability rates and increase the chances of falling into spam traps. 

Notable ISPs create spam traps to track down spammers. These mail ids look ordinary but are created to blacklist spam IPs. 

So, always create and nurture your mailing list authentically every time you use the list. 

Consider Subscribers' Choices

Whenever a subscriber unsubscribes from your mailing list, stop sending mails to them. Similarly, avoid sending mails to inactive users. It will harm your deliverability rates. 

2. Maintain Good Sender Reputation

Spam filters identify some words as 'spam' and quickly move the mails to the spam folders. While writing your mail copy, try not to use spam triggers such as 'free,' 'sale,' 'discount,' etc. 

Ensure your IP address is whitelisted and maintain a specific email frequency. Another excellent practice is to segment your lead list. 

Ask your subscribers what kind of mails they would like to receive. Segment your subscribers based on their needs and preferences and send mails that they want to receive. 

3. Don't Compromise on the Content Quality

Above all, content quality matters the only thing that matters. Even if you abide by all the Internet laws and build a good sender reputation, your mails won't see any conversion if your content is not good. 

Research your client's needs and create content based on that. If you can add value to your clients, it will help build trust among your subscribers. 

Always proofread your content before sending it. A business mail with typos or grammatical errors is off-putting and unprofessional.
