Best Practices for Mass Send Email
To send mass emails effectively, it's essential to follow best practices. Double opt-in is a must to ensure your contact list is clean and up-to-date, confirming recipients have actively signed up to receive your emails.

Segmentation is key to targeted emails that generate better engagement and deliverability. Using collected data to determine customer interests and preferences will reduce spam complaints.
Monitoring engagement metrics, spam complaints, email bounces, and click-through rates will give you a full picture of your campaign's performance and content quality.
Make sure your ESP can handle your email volume, as bottlenecking can impact complaint rates and sending times. A reputable email blast service can ensure your emails land in the inbox and get the attention they need.
Test and tweak your email templates with up to 5 variations to see what works best with your recipients. Add personalization based on demographics, behavior, or interests to reduce unsubscribes and boost click-through rates.
Don't send generic in-email content; instead, customize each email to the recipient with dynamic templates and custom variables. Be clear about what your emails are about and avoid misleading recipients with spammy subject lines or click-bait.

Email Deliverability and Reputation
Using a Gmail address for business purposes is a recipe for disaster, as it's designed for personal use and will likely flag your emails as suspicious. This can lead to temporary account disables and even lower deliverability rates.
Sending mass emails from a new domain or IP without warming it up first is also a major no-no, as ISPs won't know what to expect from it and will likely send your emails straight to the spam folder.
To protect your sender reputation and improve deliverability, it's essential to keep your list clean by using an inbuilt email verification tool to identify invalid or risky emails. This will save you on sending quota and help you avoid being flagged as a spammer.

Protect Your Reputation with Verification
Protecting your sender reputation is crucial for email deliverability, and one way to do this is by using an email verification tool. This can help you identify and remove invalid or risky emails from your list.
MailerSend's inbuilt email verification tool can scan your list of recipients to identify these issues. You can also use this tool to keep your list clean and save on your sending quota.
Invalid or expired addresses can harm your sender reputation and lead to lower deliverability rates. Using double opt-in can help you avoid these issues from the start.
Brevo's rigorous authentication process can also help protect your sender reputation by keeping spammers out and ensuring that your emails land in the inbox. This is especially important when using a shared IP address.
Using a dedicated IP address can also help improve your sender reputation, but it's essential to make sure you're using it correctly. Brevo's safety protocols, such as email authentication and setting DNS records, can help make this process easier.
Don't send mass emails from new domains or IPs, as this can lead to a one-way ticket to the spam folder. Consider using an older domain or warming up your IP before sending a large volume of emails.
Make sure your email list is clean and composed of users who have completed your opt-in. This will help improve your sender reputation and reduce the risk of your emails being marked as spam.

Avoid Misleading Recipients
You always need to be very clear about what your emails are about. Misleading recipients is covered in many data protection laws around the world, so it's a good idea to be transparent.
You can't mask an email marketing campaign under the guise of a transactional email receipt - it's shady. This will only hurt your reputation and land you in the spam folder.
Avoid spammy email subject lines or anything that might confuse your recipient. Click-bait tends to hit spam filters easily, so it's best to avoid it altogether.
Everyone hates being misled, and it's a surefire way to get your emails marked as spam. So, make sure to be honest and clear in your email marketing efforts.
Gmail and Mail Merge
To send mass email in Gmail, you can use the Blind Carbon Copy (BCC) field to keep your contacts' identities private. This is key to protecting them from scammers or other malicious actors.
You can also use a mail merge add-on, such as Mailmeteor, to send bulk email from Gmail with attachments. This can help you stand out in the inbox and get the reader to take action.
To get started, install a mail merge extension, like Mailmeteor, and add your contact list to the BCC field.

You can send bulk emails from Gmail using the Blind Carbon Copy (BCC) field. To do this, use the BCC field instead of the To field to communicate with your email list.

Gmail Limitations and Issues
Sending mass email from Gmail is not recommended for growing your business through email marketing.
You'll eventually face issues with deliverability, which means your emails might not even make it to recipient inboxes.
If your sender address ends in @gmail.com, there's a high chance that your mass email campaign will be flagged as suspicious.
Google will temporarily disable your account if your emails have been marked as spam or if you've sent a large number of undeliverable messages to invalid email addresses.
Gmail's new and stricter spam policy requires a spam rate lower than 0.3%.
An @gmail.com address for business purposes doesn't look professional.
You can use a dedicated email service like Brevo to get a sender address tied to your domain name.
Brevo's free plan includes a ready-made template to help you get started.
Gmail has a strict email sending limit, either 500 emails per day or one email to 500 different recipients.

Don't Generic Content
Sending generic email content can be a major turn-off for your audience. People may start to feel like they're not getting anything of value from your emails.

Adding personalization based on demographics, behavior, interests, or personal preferences will lead to fewer unsubscribes, higher click-through rates, and more conversions. It's a simple yet effective way to make your emails more relevant and engaging.
Email personalization can be coded into your email HTML template and most email marketing software also offers this option.

Preview

Preview is a crucial step in sending mass emails, especially when using Gmail's Mail Merge. It's essential to review your email before sending it to ensure everything looks right.
To preview your email, you'll want to show the preview to see if the attachment and merge tags appear properly. This is a great way to catch any errors before sending out your emails.
Click "Receive a test email" to make sure everything is working correctly. This will send a test email to yourself, allowing you to verify that the attachment and merge tags are displaying as expected.
Here's a quick checklist to help you review your email:

Compliance and Privacy
Using the BCC field in Gmail doesn't respect the recipient's privacy, and can lead to accidental exposure of email addresses.
Dedicated emailing software like ESPs (Email Service Providers) protect your subscribers' addresses and information by sending individual emails to each contact on a list.
Manual list cleaning in Gmail can be time-consuming and prone to mistakes, which can result in non-compliance with regulations like the GDPR.
Brevo offers GDPR-compliant features, including subscription forms and unsubscribe links, which can help you stay on the right side of the law.
Gdpr Compliance
GDPR compliance is crucial for sending mass emails.
Using Gmail to send mass emails can be problematic because you have to manually check that everyone on your list has opted in, which takes time and can lead to mistakes.
The GDPR requires an opt-in process before sending mass emails, and you must also include an unsubscribe option in the email footer.
Manually checking for opt-ins and unsubscribes can be a challenge, but tools like Brevo can automate this process with GDPR-compliant features.
Brevo automatically removes unsubscribes and hard bounces from contact lists, saving you time and effort.
Brevo also equips your email marketing with subscription forms and unsubscribe links, making it easier to comply with GDPR regulations.

What Makes You?
A bulk sender is anyone who sends a single email to roughly 5000 contacts in a day. Google has publicly referenced the 5000 threshold, but Yahoo has expanded saying that there is no exact cutoff at 4999 emails, or even 4000.
If you're sending one email to many recipients, then you are a bulk sender. And once a bulk sender, always a bulk sender, so it's essential to use best practices.
You'll be considered a bulk sender regardless of whether you're sending emails through Gmail or Yahoo. This is because both platforms have similar requirements for bulk email senders.
A single email sent to many recipients can put you over the threshold, making you a bulk sender.

Getting Started with Mass Send Email

Include a greeting line at the top of the body of your email that can be personalized to include the formal address and first name of your email recipients.
To personalize your message, type "@" and suggested fields will pop up from Gmail. You can also personalize using fields in your spreadsheet if you're sending to a contact list from a spreadsheet.
To create a new email campaign, go to Extensions > Mailmeteor > New campaign in Google Sheets. From there, you can create a new template or use an existing one and customize it with your email content, adding personalization via merge tags where necessary.

General Information and Tips
Before sending a mass email, consider your recipient list. A well-crafted recipient list can make all the difference in getting your message across.
It's recommended to segment your list based on job function, as seen in the article's example of targeting sales and marketing teams separately. This helps ensure your message is relevant to each group.
Make sure to include a clear subject line that grabs the reader's attention. A subject line that's too long can be truncated, so keep it concise, ideally under 50 characters, as demonstrated in the article's example.
