Reporting
Your email campaign results, explained
Ask how your email campaigns performed and get open and click rates compared and summarised.

Contacts

Campaigns
Create email campaigns by describing them
Describe the newsletter or campaign you want. Your assistant designs it, uses your usual sender and saves it as a draft in Mailrelay, ready for you to review and send.

- Pause the campaign that’s sending
Draft a campaign announcing our autumn sale, using my usual sender.
Your draft “Autumn sale: up to 40% off” is saved in Mailrelay, from Bloom Store. Want me to send you a test?
