When sending messages to multiple email recipients, it is essential to be aware of specific standard limits. Email recipient limits determine how many addresses you can send a single email to. Exceeding these limits can result in emails being flagged as spam, which in turn impacts their deliverability. The exact limit varies depending on factors such as your Email Hosting provider, account type, and email client (e.g., Microsoft Outlook, Gmail, Apple Mail).

What Is The Limit for Email Recipients?

Email providers implement recipient limits per email, as well as daily sending limits, to ensure efficient delivery, manage server load, combat spam, and protect their sender reputation. This includes recipients in the “To,” “CC” (Carbon Copy), and “BCC” (Blind Carbon Copy) fields. Specific limits vary between providers and account types (e.g., free vs. paid, personal vs. business).

Why Email Recipient Limits are Implemented

Email providers impose limits to prevent spam and protect user accounts. These restrictions prevent spammers from abusing single accounts to overwhelm recipients with unwanted emails, safeguarding sender reputations and recipient inboxes.

The idea behind limiting email recipients is to prevent your email address from being classified as a spammer. Sending a single email to an excessively large number of recipients, especially if they aren’t part of your contact list or expecting the email, is a common characteristic of spam and can lead to the email being flagged, bounced, or even result in the sender’s account being temporarily suspended.

Understanding email recipient limits and implementing best practices reduces potential issues related to email communication. By following these guidelines, you can improve email deliverability and lower the chances of your messages being labelled as spam, or even blacklisted, helping you connect more effectively with your customers.

Best Practices for Sending Bulk Emails

To optimise email delivery and avoid spam filters, follow these best practices when sending to multiple email recipients:

• Limit Recipients – Keep to the specific sending limits of your email service provider to improve deliverability and open rate while avoiding spam filters and account restrictions.
• Avoid BCC – Refrain from using BCC excessively to evade spam designation. It’s better to use a dedicated bulk email tool that handles individual sending.
• Group Recipients – Send emails to cohesive groups to enhance relevance and engagement. Sending generic emails to a large, unsegmented list is a common characteristic of spam which can negatively impact your sender reputation.
• Use Bulk Email Tools – Employ specialised services for bulk email campaigns to manage outreach effectively. These services are specifically designed to manage high volumes, handle opt-ins/opt-outs, track engagement, and maintain a good sender reputation.
• Manage Attachments – Minimise attachment sizes to prevent delivery issues due to file size limits. If files are large, consider using cloud storage links instead of attaching them directly.

Email Spam Filters

Automated spam filters evaluate incoming emails for spam characteristics, potentially diverting suspicious messages to spam folders or blocking them entirely. Effective filtering enhances email security and user experience by mitigating the impact of unwanted emails.

Bandwidth Allowance and Emails

Monthly bandwidth allocations in hosting plans include email data transmission. Bandwidth usage includes uploading and storing email data on servers, as well as factoring in message sizes and attachments when calculating usage. Exceeding the allocated bandwidth may necessitate plan upgrades to maintain email service reliability.
