BYO AWS credentials is not currently available. useSend uses Amazon SES under the hood to send emails. ### Can useSend receive inbound emails? No, inbound email is not currently supported. There is an open discussion about adding support for receiving, parsing, storing, and exposing incoming messages. ### Which ports should be exposed for a self-hosted useSend instance? Use port 3000 for the dashboard and port 3001 for the marketing site. Open both ports in the firewall if you need to access useSend from another device. ### Can existing applications send through useSend using SMTP? Yes, useSend provides an SMTP relay that works with any app or framework. It is also useful with services such as Supabase. ### Why might the self-hosted dashboard show a failed SES callback? The dashboard can report the SES callback status as Failed without explaining the underlying reason. This issue is useful for troubleshooting missing or failed SES callback configuration in a self-hosted setup. ## Alternatives - Brevo: All-in-one solution for email, SMS, marketing automation, transactional messaging, integrations with CMS and e-commerce platforms, and tier… - Klaviyo: Optimize customer engagement with multichannel messaging, CRM integration, and AI-driven analytics, unifying marketing, service, and data f… - Listmonk: Listmonk is a fast, standalone, self-hosted newsletter and mailing list manager packed into a single binary. - Mailchimp: All-in-one platform for creating, automating, and sending marketing emails, building landing pages, running ad campaigns, and analyzing aud… - Mailgun: Mailgun is email automation for developers. - SENDER: Create responsive emails with a drag and drop editor, set up automated email and SMS campaigns, integrate with ecommerce tools, and track a… - Sendgrid: Scalable email delivery for transactional email SendGrid transparently handles DKIM, SPF, ISP rate limits, content inspection, bounces, and… --- Source: Our Local Host (https://ourlocalhost.com/app/6899/usesend), the self-hosted and open-source app directory.
