Email marketing

Send through your own SES. Stop paying per contact.

EmailSendX is the campaign builder, A/B tester, deliverability dashboard, and analytics stack — pointed at the sending account you already pay for. Eleven providers. One bill that doesn't grow with your list.

No credit card. Connect SES in 5 minutes. Cancel any time from workspace settings.

Bring your own sender

Eleven providers. Same dashboard.

Plug in whichever sender you already pay for — or run two side-by-side. Bulk through SES, transactional through Postmark, warm 1:1 through Gmail. We don't care. Your campaign builder, A/B tests, and analytics stay the same.

  • Amazon SES

    AWS native

  • SendGrid

    Volume sender

  • Brevo

    EU-friendly

  • Mailgun

    Developer first

  • Postmark

    Transactional king

  • Resend

    Modern API

  • Gmail (OAuth)

    For warm 1:1

  • Generic SMTP

    Anything else

Connect more than one per workspace. Pick the right sender per campaign — we route the mail and stitch the analytics back together.

Who it's for

Built for teams that manage email at scale

If you run campaigns for multiple brands, clients, or business units, EmailSendX gives you one premium control plane without giving up ownership of your sending infrastructure.

Digital Agencies

Manage every client from one login with isolated workspaces, shared templates, and clear team permissions.

  • Unlimited client workspaces
  • Faster campaign turnarounds

SaaS Founders

Operate multiple SaaS products seamlessly with dedicated environments for each app, ensuring clean data, branding, and delivery control.

  • Separate sending domains per product
  • Centralized performance insights

Manage Multiple Clients

Handle multiple clients efficiently with structured workflows, clear approvals, and organized campaign management in one dashboard.

  • Streamlined client approvals
  • Organized campaign workflows
Why agencies

Made for the way agencies actually work.

Every feature below exists because we kept running into the same gap ourselves and across operator conversations on Twitter, Reddit, and Indie Hackers — things Mailchimp, Klaviyo, and ActiveCampaign quietly leave to the customer.

Pillar 01

One command center. Every client isolated.

Each workspace is its own sealed environment — contacts, templates, providers, automations, and team members never leak across clients. Switch between them with a single keystroke. Onboard a new brand in under 90 seconds.

  • Unlimited workspaces on every paid plan
  • Per-workspace physical address and sender identity
  • Role-based access: Account owner, Team Members
  • Audit log for every action, scoped to the workspace

Built where the incumbents can't follow.

Mailchimp and Klaviyo charge per subscriber because they own the infrastructure. EmailSendX is the control plane — you own the sending pipe, we never mark up a single send. Drill into each row below — the scorecards above are a summary of this same checklist.

Deliverability

If your email lands in spam, none of this matters.

Cheap sending is worthless if half your campaign goes to the promo tab. Every EmailSendX workspace gets the same deliverability checklist enterprise senders run — baked into the dashboard, every plan, no upsell.

  • BIMI, SPF, DKIM, and DMARC verified on every connected domain — broken auth gets flagged before the campaign goes out.
  • Volume warm-up schedules that ramp your sending gradually so a fresh domain or IP doesn't torch your sender reputation on day one.
  • RFC 8058 one-click unsubscribe headers, suppression list, and double opt-in forms baked in — Gmail and Yahoo bulk-sender rules covered.
  • Live blacklist monitoring across the major RBLs. If you land on Spamhaus, you find out from us, not from a client.

Email marketing FAQ

Sending, deliverability, and the stuff in between.

Pricing questions live on the pricing page. Below is everything else operators ask before they connect their first provider.

Eleven: Amazon SES, generic SMTP, SendGrid, Brevo, Mailgun, Postmark, Resend, Gmail OAuth, Oracle Cloud (OCI) Email Delivery, ZeptoMail, and Elastic Email. You can connect more than one per workspace and pick the right sender per campaign — transactional through Postmark, bulk through SES, warm 1:1 through Gmail, for example.

Yes. Order your connected providers by priority. If SES throttles, Postmark picks up. If a hard bounce spikes, Mailgun takes over. You see the full event log in the analytics panel so you know exactly where every message went.

Yes. Test subject lines, sender names, send times, or whole content variants in a single experiment. Pick a sample size, set the metric (opens, clicks, conversions), and the auto-winner ships the leader to the rest of the list.

We run SPF/DKIM/DMARC checks on every connected domain, support BIMI, schedule volume warm-ups, monitor major blacklists, and add RFC 8058 one-click unsubscribe headers automatically. Suppression list, double opt-in forms, and CAN-SPAM/GDPR-compliant footers are baked in.

Yes — a full REST API for contacts, lists, campaigns, automations, and templates, plus webhooks for opens, clicks, bounces, complaints, and unsubscribes. Pair them with the multi-workspace model to spin up new client accounts programmatically.

Yes. CSV import supports the standard column names exported from Mailchimp, Klaviyo, and ActiveCampaign. Suppression history and unsubscribes are preserved if present in the export.
