There is not a limit on the number of emails you can send daily - if you need to send out a message to your list of 10 or your list of 10,000, you can easily do so with your AWeber account.
We do not bill you based on the number of messages that you send - only on the number of subscribers on your list, so you can send as few or as many messages as you need to without worrying about the cost. Take a look at our pricing page for more information on billing.
Keep in mind that while we do not limit the amount of email that you send daily, you will still want to make sure that you are sending content that your subscribers expect to receive. Sending multiple messages to your list per day could potentially impact your subscribers' desire to remain on your list, or cause them to mark your messages as spam, which could affect your deliverability.
AWeber offers hundreds of templates you’re welcome to use! If you would ever find yourself wanting to modify an existing template or would like a custom template built for you to reflect your branding, our Template Team would be happy to modify existing templates or design a custom template for you!
