A bulk email sender is only useful if the mail lands in the inbox. SESender helps teams send high-volume email to opted-in subscribers with validation, authentication, warm-up, seed testing, engagement tracking, and automatic suppression built into the workflow, plus SMS from the same workspace.
Validate addresses before a send, protect sender reputation with dedicated sending domains and SPF, DKIM, and DMARC, check inbox placement on seed accounts, prioritize engaged subscribers, and suppress hard bounces, complaints, and unsubscribes. Send from the dashboard or with POST /api/v1/email/send. SESender is the campaign workspace, not an email provider. Delivery runs through an email provider you connect: SendGrid, Mailjet, Brevo, Postmark, SparkPost, Amazon SES, Resend, Nodemailer/SMTP, Mailgun, SMTP.com, TurboSMTP, Customer.io, or UniOne.
Send only to people who opted in. Purchased lists are not allowed. Starter is free and includes 100 SMS and 100 emails a month. Essential is €250/month, Professional is €750/month, and Enterprise Pro is €1,250/month. New accounts include €50 in free credits, and no credit card is required. Related paths include the API docs, the bulk SMS platform, email marketing for affiliates, email providers, and the plans on the landing page.
