You must be wondering how is it even possible to send bulk emails from Gmail.

We all know that Gmail has set certain restrictions for sending bulk emails. They restrict such action because they don’t want to hamper the users’ experience on their platform. Also, sending 10,000 emails in one go will put your email deliverability rate at risk.

That doesn’t mean you can’t send mass emails; You can, and that’s what you will learn in this blog — a step-by-step way to send 10,000 emails without spamming or getting blacklisted. 

The solution to send 10,000 emails at once

Saleshandy will help you complete this task in the easiest way possible.

Saleshandy is an email outreach tool that helps you scale your email efforts and become more effective. Its power-packed features boost your engagement and deliver your email right into the primary inbox.  

Using key features like sequence, you can create and send bulk emails without spam. You can compose the email exactly the way you like, upload the list of prospects, and even schedule it to be sent on a particular date/time. 

We have mentioned that we let you schedule all these emails to be sent at one go, but the sending will be programmed as per your email service provider’s daily email sending limit.

It is not recommended to send multiple emails at one go as it may damage your email account reputation and result in your emails ending in the recipient’s spam box.

Using Saleshandy, one can send campaigns (sequences) from Gmail, Outlook, or any other email service provider without decreasing their email domain reputation.

Additionally, using Saleshandy, you can add follow-ups (steps) to the bulk email campaign (sequence) that you are sending, freeing you from doing the task manually and increasing the reply rate.

It might take a day or two to send all those emails scheduled, depending on your email service provider’s daily email sending limit.

But this and the drip frequency optimization technology (automatically placing short random time intervals between sending two consecutive emails) that we use while sending your campaign (sequence) ensures that your emails dodge the recipient’s spam filters and get you higher email deliverability though you are sending more than 10,000 emails from your email account.

You might be thinking about how to send bulk emails from Gmail using Saleshandy, relax. All you have to do is get started with the following simple steps.

Step 2: Create your email list

After the first step, you have to create a list of your recipients to whom you want to send a bulk email from Gmail. Always make sure you have a clean list with your recipients’ names and email addresses.

Having a name will help your bulk mail sending look more personalized and will be a great assist in avoiding email spam filters.

Create your email list of multiple recipients

Step 3: Create a sequence

Once you’ve prepared your list of prospects in an Excel spreadsheet or Google Sheet, proceed with creating a sequence on Saleshandy. 

A sequence is where you compose your email the way you want it. 

Here you can add personalization to make your email campaigns (sequences) more effective. Additionally, you can use pre-saved templates that will help you get started.

Step 4: Compose your email

This step is the most important of all. Here you begin the actual communication with your recipients.

It’s good to start by creating an informative and creative subject line that compels recipients to click.

Create a comprehensive email by making it personal with custom fields. Cut to the chase, offer some value to your prospect and end your message with a clear call-to-action

After creating the sequence, you can add steps. You can add 49 steps to your bulk email campaign (sequence). Don’t forget to add a follow-up (step).

Add merge tags to personalize your email

Handy tip: To boost open rates while sending mass emails, always make sure you don’t use spam words and too many links in your email. If the Gmail algorithm detects that you send spam emails, it will affect your email deliverability.

Step 5: Upload the list in CSV format

So if you want to send 10000 emails at once, you have to create 5 different email lists to optimize the process—each list with not more than 2000 emails.

Head to prospects in the sequence, click on add prospects and upload your CSV file. While uploading the list, you get an option to clean and verify the email list.

This will remove spam emails and invalid emails. Verifying and cleaning the emails reduces email bounces and improves your credibility to send bulk emails more efficiently.

Step 6: Send or schedule the email

This brings the end of the process where we show you how to mass send emails. You will have to activate your email sequence, and your sequence will be sent as per the time you have set. You can change the time of your email by going to the settings tab. 

We will keep a short time interval of a few seconds between your emails. This will help to avoid the spam folder and make the process look more human-like.

You must be thinking that is this the best possible way to send 10000 emails at once and isn’t it really possible to do it in a day?

The reality is that it is impossible to send 10000 or more emails from a single email address on the go in a single day without triggering spam filters.

Handy tip: Saleshandy also gives you an option to add the Unsubscribe link within your email. You can add the Unsubscribe tag at each stage of the email campaign (sequence) so that the recipient can opt out from your email list if they find the email not relevant to them or think you send spam emails.

How timing works in Saleshandy

  • Google keeps track of how many emails are sent in 24hrs from a particular account
  • As per the Google policy, you can send 2000 emails/day with a G Suite account whereas the maximum email allowed in free Gmail account is 500 emails/day
  • So let us say with your G Suite account you began a campaign (sequence) of sending 10000 bulk email on 1st December at 10 AM and it took 3 hours to completely send 2000 emails which got over at 1 PM. 
  • Once you complete the daily sending quota, for the next 24 hours your campaign (sequence) will be paused. You won’t be able to send an email from your G Suite account. However, during this time you can receive and schedule emails.
  • So your next campaign (sequence) will begin when you activate your sequence. You will have to activate it exactly after 24 hours of your last email sent i.e on 2nd December at 1 PM. The same process will continue for the next 5 days, i.e if you started the campaign (sequence) on Monday, it will finish on Friday.

I strongly believe your confusion is clear about how to send bulk emails from Gmail or Outlook.

Important notes:

  • Using this feature, you can send 200, 1600, or 5000 emails in a day depending on your Saleshandy plan type.
  • Saleshandy uses a drip method for sending mass emails by putting time intervals between two consecutive emails and respects Gmail’s daily sending limit.
  • It doesn’t matter how many sequences you do in a day Saleshandy will track each and every one of them.

Remember, it will take half an hour or so to get the hang of it, and the advantage of it will last a lifetime.

There’s one more step in the process that’ll allow you to optimize your emails against spam filtering, helping you make the most of your campaigns (sequences).

Optimizing your campaigns (sequences) will help you deliver your emails directly into your prospects’ primary inbox folders, where they are more likely to be opened and replied to.

In the next section, we’ll explore how to set up your email campaigns (sequences) against spam filtering.

Avoiding spam and promotional filter for your emails

While it’s pretty easy to schedule and send emails to your prospects in bulk – they aren’t guaranteed to land in their primary inbox. Billions of emails are sent every day, and not all emails are treated equally on the recipients’ end. 

You might have seen this in your inbox as well – where a good chunk of emails is either in promotions, updates, or spam folders.

It’s most likely that if you send out your bulk email campaigns (sequences) without optimizing for deliverability, your emails will end up in spam. 

So to ensure your bulk outreach emails don’t get buried under other promotional emails, let’s first understand why they end up in spam and how to fix it.

Why are your emails landing in spam and promotions

Both you and your prospects’ email service providers do a series of checks on each email before filtering them into relevant folders within the inbox.

This helps them de-clutter the inbox from spam and promotional emails that might not necessarily need your prospects’ immediate attention. 

Failing these checks would signal the email service of your email and its content being promotional, getting it filtered into respective folders.

Let’s take a look at these checks so you can optimize your bulk email campaigns (sequences) for reach and conversions.

SPF, DKIM, DMARC records

SPF, DKIM, and DMARC records are used to verify an email sender’s source for authenticity, i.e., if the email is being sent by the person, it’s claiming to be from.

These records are added on the domain level, so once authenticated, they’ll automatically apply to all your emails being sent. Every email bears the results of these checks in its HTML code, as seen below.

Spf record in your email

Not having a “pass” for these checks will get your emails filtered into spam folders. 

Domain reputation

Whenever prospects open an email and find it irrelevant, they usually try to unsubscribe from such emails. But several outreach emails don’t include links to unsubscribe from future communications, which only leaves recipients with one option – reporting it as spam.

If you’ve been sending bulk outreach emails for a while now, chances are you might have had a few of your emails being reported as spam by your prospects.

This is a bad signal, and a few frequent instances of such reports can get your domain into spam blacklists. 

Every time you send an email, your prospect’s email service checks your domain against listings in domain blacklists. And if you’re listed in one of these domain blacklists, your emails are highly likely to get delivered to spam folders.

Bad engagement rates & high sending rates

If your previous email outreach campaigns (sequence) have had low engagement rates regarding opens, clicks, and replies, it’s another signal of your emails’ promotional nature. Email services use algorithmic systems to separate important emails from promotional ones. 

So when your past emails have gone unopened, it flags the email service of your content being irrelevant for your recipients, which triggers spam filters. 

Low engagement often results from highly templated content – without any form of personalization that might appeal to your prospects. 

Personalizing bulk outreach emails can often be time-consuming, which is why the majority of promotional emails are barely personalized, if at all. 

Similarly, when you use bulk email marketing services similar to Sendgrid, Mailchimp, etc., your emails are being sent from public servers all at once.

When multiple of your emails with similar content are received at your prospects’ email service(e.g., Gmail), it can detect the source and mark those emails as promotional. 

How to send bulk emails without spamming

Personalize your email content

When you reach out to your prospects in bulk, ensure to personalize your emails, so they’re more engaging and are more likely to get responses.

Using mail merge on sales engagement platforms like Saleshandy, you can personalize templates and email content on the scale, using minimal effort while still sending outreach emails in bulk.

You also get real-time writing assistance while composing your email. The assistance includes 4 real-time suggestions that will help you write better emails.

Set up DKIM, DMARC, SPF, and Custom domain

When you send out outreach emails from your GSuite or Outlook accounts – your emails aren’t authenticated with DKIM, DMARC, and SPF records by default.

Also – if you’re sending emails with tracking links, they’re likely to trigger spam filters as they’re embedded into your HTML code. Tracking links also originate from a domain different from the one you’re sending your email, making your email look more spammy.

Custom domains mask these links with your domain, thereby making your email look more cohesive and less likely to be filtered into promotional folders. 

If you’re using Saleshandy to send your bulk outreach emails, you can set up a custom domain to be enabled on all your email campaigns (sequences).

Verify emails and use unsubscribe links

When you send emails to prospects with unverified emails, a portion of them might bounce. Email bounces, similar to spam reports, also signal your email service of promotional email activity, which in turn might hurt your email deliverability.

To ensure none of your emails bounce, you can either have double opt-in forms on landing pages you use to generate leads or verify them before reaching out to them.

Using Saleshandy, you can verify all your prospects in a single click, so this way, you can omit sending emails to prospects with unverified emails. This will eliminate email bounces from your bulk email outreach and improve your email deliverability.

Similarly, add unsubscribe links to all your emails. Outreach platforms like Saleshandy include unsubscribe links by default, which are also customizable. This will help you be free from spam reports, stay out of domain blacklists, and keep your email lists clean.

Unsubscribe links are also mandated on all outreach emails by the FTC per the CAN-SPAM act, and non-compliance could result in hefty fines apart from other forms of punishment.

Make sure you follow the above-mentioned practices to send bulk email without spamming.


You perfectly know how to send bulk email in Gmail if you have reached here. 

Using an email outreach tool for this task is more accessible. And it makes you look professional as a sender, and most important of all, it doesn’t impact your email deliverability. 

Using the traditional (CC and BCC) method, email deliverability is at stake, and your email will lack many essential factors, one of them being personalization. 

So, try to avoid the traditional approach as much as possible while sending 10000 emails or more.
