Subject line ideas for your emails
You describe what your email is about. Aura suggests several subject lines, which you can regenerate or refine. You keep the one that suits you.
Brevo is French business software, formerly Sendinblue. You use it to write to your customers (newsletters, SMS, WhatsApp), keep a customer list, and chat with visitors to your site. Its AI assistant is called Aura. It suggests email subject lines, writes and refines your copy, creates images, and helps you sort your contacts and read your results.
Brevo has a free plan. The recommended plan to start with: Free, €0 per month. Prices checked on October 3, 2026 on the vendor’s official page.
Who it’s for: small and midsize businesses, shop owners, and nonprofits that send newsletters and keep track of their customers without a dedicated marketing team.
You describe what your email is about. Aura suggests several subject lines, which you can regenerate or refine. You keep the one that suits you.
Aura writes a paragraph from your description, or takes an existing text to shorten it, correct it, or change its tone. Nothing changes without your click: you choose to replace, copy, or start over.
The editor includes an image generator: you describe the visual, and it draws it. Aura can also propose the full layout of a campaign.

The price rises with the number of emails sent each month. Two add-ons are available for sales follow-up: Sales Essentials at €29 per month and Sales Advanced at €59 per month. Prices taken from Brevo’s help center on October 3, 2026.
| Plan | Price | Who it’s for |
|---|---|---|
| Free Recommended to start | €0 per month | Getting started, small volumes |
| Starter | from €7 per month | Regular sends without the Brevo logo |
| Standard | from €17 per month | Small marketing team |
| Pro | from €499 per month | High volumes and several channels |
| Enterprise | Custom pricing | Large organizations |
300 emails per day, up to 100,000 stored contacts, a single user, and Aura for writing. Emails carry the Brevo logo. The plan has no time limit.
The free plan is enough to try Aura and send a newsletter to a few hundred contacts. Move to Starter to remove the Brevo logo, to Standard if you want automated sends. The Pro plan is only worth it for high volumes.
