What is bulk email software?

Bulk email software is used to send emails to large lists of contacts. Sendinblue is an example of bulk email software. This type of email service is not to be confused with free email providers like Gmail and Outlook. These services are intended for one-to-one emailing and have strict daily sending limits that make them unsuitable for sending bulk emails. To send a commercial email to a large list you’ll need to invest in dedicated bulk email software. Typically, this type of software comes with additional features to support email design, email list management, and reporting.

How can I send bulk emails?

Select the best bulk email sender suited to your needs (like Sendinblue). Subscribe to a plan that supports the volume of bulk emails you plan to send. Import your existing contacts onto the platform or start gathering new subscribers via email subscription forms. Start planning your first email marketing campaigns. Use tools like the drag and drop editor to create an eye catching email design. Schedule your email to send at the best time for your audience.

How can I send bulk emails for free?

You can send up to 300 emails per day on Sendinblue’s free plan and store unlimited subscribers. You don’t need a credit card to sign up and you can cancel your account at any time.

To send a bulk email campaign to more than 300 recipients per day you’ll need to sign up to one of our paid plans (starting at $25 for 20,000 emails a month).  

How to send bulk emails without spamming?

Your email lists should be 100% opt-in, i.e. subscribers have explicitly consented to receive email communications from you. Include a clearly visible unsubscribe link in every email. Never purchase email lists.

Avoid click-bait subject lines and make sure your email content and frequency respect your ‘signup promise’ (what you said you’d email about and how often). When subscribers know what exactly emails to expect and when, they’re less likely to mark you as spam.

How do you make sure email does not go to spam?

While there’s no way to guarantee your email doesn’t go to spam, there are a number of email deliverability best practices that’ll help you reach the inbox. Common techniques include 

  • Authenticating your domain name as part of your DKIM signature (the technical email signature that proves your identity to ISPs)
  • Cleaning your email list regularly and removing unengaged contacts to maintain high engagement rates and a trusted sender reputation among ISPs/webmail providers
  • Using a double opt-in confirmation (easily set up with Sendinblue) to avoid misspelled email addresses. 

Avoiding spam trigger words (free, cheap, bargain, $$$, bonus, urgent, don’t wait!, etc.) in your email subject line and content.
