Can I send 100 emails at once in Gmail?

Sending capacity in Gmail

Gmail places daily and hourly caps on how many emails a single user can send to limit spamming and abuse. Before mass emailing, it’s important to understand Gmail’s sending limits:

  • Daily limit – Gmail allows up to 2,000 messages per day, rolling 24-hour period
  • Hourly limit – The hourly limit is based on your account history, but typically allows up to 100 messages per hour

As long as you structure your email campaigns thoughtfully and within these limits, you should have no issues sending messages to even the longest contact list.

Steps to send 100 emails from Gmail at once

While staying below the 2,000 daily total, you have flexibility in how you schedule large mailings. Here are different ways to reach up to 100 recipients at once:

Use the BCC field

The easiest way is to put all contacts in the BCC (blind carbon copy) field separated by commas.

  1. Compose a new Gmail message
  2. Draft your email content
  3. In the BCC field, input up to 100 contacts separated by commas
  4. Hit send!

This allows you to hide the recipient list and send up to 100 copies of the personalized message in one batch.

Upload CSV contact list

For managing especially long contact lists, upload your subscriber data as a CSV file when composing a message.

  1. In Contacts, export your mailing list as a .CSV file
  2. Compose a new Gmail message
  3. Click Attach files > Import CSV to upload contacts
  4. Check up to 100 recipients and hit send!

The CSV method makes it easy to keep stored subscriber lists and selectively send to groups whenever needed.

Schedule through Google Sheets add-on

Alternatively, use a third-party Gmail add-on tool for expanded scheduling options. For example:

  • Yet Another Mail Merge – Free Google Sheets add-on to batch send personalized mail merges
  • Mailshake for Gmail – Email drip campaigns starting at 100 emails per month

These tools connect Gmail to other apps for automating sends to large lists while respecting daily/hourly limits.

Best practices for mass Gmail emailing

When planning major email campaigns, be sure to optimize both deliverability and user experience:

  • Personalize subject lines with subscriber names
  • Offer an unsubscribe link in each message
  • Spread out sends over multiple days if needed
  • Proofread carefully before hitting send!

Following Gmail’s sending guidelines coupled with these tips will allow you to effectively reach 100+ subscribers while providing value.

Frequently Asked Questions

  1. Can I send 200 emails at once from Gmail?
    Sending 200 emails at once would exceed the typical 100 email per hour limit. It is better to either split your mailing list in half and send to up to 100 recipients at a time, or use scheduling / drip campaigns over multiple hours or days.
  2. Is there a limit on Gmail group email? Groups follow the same sending limits – no more than 100 emails per hour and 2,000 emails per day from a single account. Manage large groups by segmenting into smaller custom contact lists if needed.
  3. What happens if I exceed Gmail’s sending limits?
    If sending capacity is exceeded too frequently, Gmail may throttle additional sends that day or trigger spam filters and blocks. Make sure to carefully pace mailings to avoid disruptions.
  4. Can I automate or schedule large Gmail sends?
    Yes, Gmail integrates with third party tools like Yet Another Mail Merge, Mailshake, Mailchimp and more to automate sending to contact lists while respecting daily and hourly limits. These are great for managing newsletters and notifications.

  6. What is the maximum contacts allowed on a Gmail CSV import?
    Gmail currently allows importing up to 100 recipients at a time from a contacts CSV file or spreadsheet.
  7. Can I BCC my entire Gmail contacts list at once? No, even if you kept entries under 100, attempting to add your full contact list to BCC could get flagged as spam. Best practice is breaking up contact segments <100.
  8. Is it safe to bulk email from Gmail?
    Yes, Gmail mass sending is safe and reliable when following Google’s usage policies – staying under daily/hourly quotas and avoiding spam triggers. Use dedicated tools like Mail Merge add-ons for best results.

  10. What third-party apps integrate best with Gmail?
    Yet Another Mail Merge and Mailshake are two of the most popular and secure tools for managing high volume email sends from Gmail while avoiding bot triggers.
  11. Can scheduling multiple sends bypass Gmail limits? No, features that attempt to work around the hourly or daily caps may get your account flagged for spam. It’s better to use trusted scheduling tools to queue emails within policy.
  12. Is it safe to import my email contacts into third-party apps?
    Be cautious when granting permissions to your Gmail contacts. Vet tools thoroughly and ensure adequate data protections before syncing sensitive subscriber information.
  13. Can I segment long contact list by first letter of last name? Yes, a simple way to break large lists into smaller batches is segmenting by recipient name, such as send to A-D today, E-H tomorrow. Personalization can aid deliverability.
  14. Is MailChimp fully compatible for sending emails from Gmail?

  16. Is it better to Cc or Bcc multiple Gmail recipients?
    BCC is preferred when sending to large batches of recipients to hide addresses. CC visibly exposes all recipients to each other.
  17. What triggers the Gmail spam algorithm for mass sends?
    Factors like inconsistent sending patterns far outside your normal levels, suspicious click metrics, message complaints or blocks can flag bulk emails as spam.
  18. Will scheduling emails overnight bypass Gmail limits? No, scheduled sends via plugins still count towards sending quotas regardless of what time they are set for. Proper throttling is required 24/7.
  19. Can I import part of a large Gmail contacts list at once? Yes, best practice is to split extremely long contact lists into smaller groups of <100 before importing batches via .CSV over time to assemble mass mailings within policy.
  20. If my email gets marked as spam, can I request Gmail review the block?
    Recipient spam markings can lower future deliverability. If you believe the block was in error, you can submit an appeal to Gmail, but there is no guarantee of reversals. Proceed cautiously.
