If you're having challenges sending your email, please double check the size of your attachments and size of your list.
Within Apto you are limited to sending 5,000 emails per day and attachments must be smaller than 25MB. If you are working with large attachments we recommend converting them to a .zip or .rar file prior to sending.
Single emails sent using the email author or composer in Apto don't count toward this limit. There’s no limit on sending single emails to contacts in your Apto account directly from property, company or deal.
