How can I send 10k email a day?

It is generally not recommended to send 10,000 emails in a single day. Many email providers have limits on the number of emails that can be sent in a day, and sending such a large volume of emails could potentially result in your account being suspended or even closed. 

Sending 10,000 emails in a day is no small feat, and it requires careful planning and the right tools to be successful. One of the first steps in achieving this volume of email outreach is to choose the right email service provider (ESP). While some providers, such as Google Workspace, may have lower limits on the number of emails that can be sent in a day, others, such as SendGrid or MailChimp, can handle much higher volumes. It's important to do your research and select an ESP that can support your needs and help you achieve your goals. In addition to choosing the right ESP, you'll also need to consider factors such as your sending reputation, email deliverability, and the quality of your email list. 

Additionally, sending a large volume of emails in a short time can be perceived as spamming, damaging your reputation and making it difficult for your emails to reach their intended recipients.

If you do need to send a large number of emails, it is important to do so in a responsible and strategic manner.

Here are a few tips for sending a large volume of emails without being perceived as spam:

Build a targeted list:

Instead of sending emails to a large, generic list of recipients, focus on building a targeted list of people genuinely interested in your product or service. This can help improve the chances that your emails will be opened and acted upon.

Use segmentation:

Segment your email list into smaller groups based on factors such as location, interests, or purchasing history. This can help you create more relevant and personalized messages, which can improve the chances that your emails will be engaged.

Use an email service provider:

An email service provider (ESP) can help you manage and send your emails in a more efficient and professional manner. Many ESPs offer features such as scheduling, automation, and analytics that can help you optimize your email campaigns and avoid being perceived as spam.

Follow best practices for email marketing:

Be sure to follow best practices for email marketing, such as including a clear subject line, using a professional tone, and including an unsubscribe link. This can help ensure that your emails are compliant with laws and regulations and that your recipients are more likely to engage with your messages.

It is possible to send a large volume of emails, but it is important to do so in a responsible and strategic manner.
