Our platform sets no limits to the maximum number of recipients that can be inserted into an email list. That being said, there are some facts worth mentioning as regards uploading or processing email lists that contain hundreds of thousands of recipients:
- Uploading a big email list may take a while
- Browsing into other pages of our system may be slower while uploading
Also, remember that browsing into an email marketing campaign that has been sent to a big email list might make opening some of your account pages a bit slower. For example, when looking at reports, the Recipient Activity page may take a bit longer to open than usual. That is to be expected if the number of recipients reaches several hundreds of thousands.
