Hi subscriber,
nuevoMailer ESP v.3.5 has just been released. Here are the highlights:

• Minimum required PHP version is 7.1. Up to PHP 8 is also fine.
• Multi-threaded sending as default. As you know user campaigns are sent in parallel. But now each campaign can be sent in multiple threads. You can still use a single thread if you want.
• Updated interfaces.
• Mailjet webhook endpoint. Improved Amazon, SendGrid, MailGun endpoints.
• You can read more on these changes here: what's new in v.3.5.
