Clickable preview with example data. Actual results vary.

Sending accounts

Send from the mailboxes you already have, or from hosted MailRush email accounts on your own domain.

Your own mailboxes

Connect any provider that offers SMTP and IMAP, as many accounts as you need. SSL and STARTTLS connections, with a login test before an account is used.

Start free trial

MailRush email accounts

Hosted mailboxes on your domain, on a shared-IP server ($15/month) or a dedicated-IP server ($29/month), with $5/month for each additional mailbox. A paid add-on to your plan.

See plans

Domain setup and Check DNS

Use your own domain or register a new .com, .net or .org through MailRush ($20/year). Check DNS compares your published A, SPF, DKIM, DMARC and MX records with what your account needs.

See plans

Keep your current email provider

Choose Primary mail hosting, or Outgoing campaigns only to keep your MX records. Reply forwarding brings replies back to MailRush when you keep your provider.

See plans

Per-account sending limits

Up to 100 emails per hour and 600 per day for a MailRush email account, and 200 per hour and 1,000 per day for your own accounts, within your plan.

Start free trial

Campaigns and sequences

Automated first emails and follow-ups that pace themselves and stop at the right moment.

Multi-step sequences

A first email plus follow-up steps sent a set number of days apart. A follow-up without its own subject is sent as a reply in the same conversation.

Start free trial

Stop strategy

Stop a contact's follow-ups when they reply, click or open. Unsubscribed, bounced and suppressed contacts always stop.

Start free trial

Schedule and pacing

Choose sending days, hours and time zone, and the minimum delay between two emails of the campaign (30 seconds by default).

Start free trial

Daily limits and ramp-up

Set each campaign's daily sending limit and let it grow automatically by a daily percentage up to the maximum you choose.

Start free trial

Audiences by tag

Pick the tags a campaign sends to. While it runs, contacts you add later to those tags are emailed automatically.

Start free trial

Previews, tests and duplicates

Preview each step with a real contact's data, send yourself a test of exactly that version, and duplicate a campaign to reuse its sequence.

Start free trial

Personalization and content

Write once and make every email read as if it were written for one person.

Personalization fields

Insert contact data such as {{first_name}} or your own fields {{custom1}} to {{custom6}} in subjects and bodies.

Start free trial

Spintax with AI suggestions

Vary your wording with nested spintax such as {Hi|Hello}. Spintax AI suggests variations for a subject or body that you review before applying.

Start free trial

Reusable templates

Save emails as templates with their tracking and unsubscribe options, and apply them to any step. Write in the editor or in HTML with a live preview.

Start free trial

Copy and sequence analysis

The campaign report flags common spam trigger words and checks personalization and the call to action of your sequence.

Start free trial

Contacts and lists

Import, organize and clean your audience before you send.

CSV import and tags

Import contacts from CSV with field mapping and organize them with tags. An address exists only once in your organization, so duplicates are skipped.

Start free trial

Email validation

Validate selected contacts, single addresses from the Dashboard, or addresses through the API. Invalid contacts are skipped by campaigns.

Start free trial

People Finder

Find people at a company domain and reveal their email addresses with People Finder credits, then save them as contacts. 15 credits are included every month.

Start free trial

Unsubscribes and Suppression List

Add an unsubscribe link to campaign emails, and every campaign email carries a List-Unsubscribe header for email apps' unsubscribe button. Suppress single addresses or whole domains.

Inbox and replies

Every reply from every sending account in one place.

Automatic reply detection

MailRush checks your sending accounts' inboxes and matches replies to the emails you sent. Replies are counted per campaign and can stop follow-ups.

Start free trial

One Inbox for all accounts

Replies grouped into conversations, with Others for unmatched mail and Sent for your outgoing emails. Search, filter by campaign or mailbox, and see new replies without reloading.

Start free trial

Reply from MailRush

Answer a conversation from the Inbox with the original message quoted. Read and unread status is kept in MailRush without changing your mailbox.

Start free trial

Deliverability and protection

Tools that help protect your sender reputation. No tool can guarantee inbox placement.

Email warmup

Up to 10 warmup emails per day from each account to mailboxes controlled by MailRush, with inbox and spam placement shown on the Warming page. Included in every paid plan.

See plans

Feedback Loop

Sender health, bounce, complaint and unsubscribe rates, blocked and rejecting recipient domains with the main reason, active sending restrictions and a 30-day trend.

Start free trial

Automatic suppression

Hard bounces and clear spam complaints suppress the contact, and recipients whose domain has no mail server are marked invalid.

Start free trial

Recipient provider limits

Daily limits per provider, such as 300 per day for Gmail, Outlook and Yahoo, for each sending address and domain. Emails over a limit wait for a later day.

Start free trial

Automatic pauses

Sending to a provider pauses after a high bounce rate, or for 1 hour to 1 week when its bounces report spam, a blocklist or abuse.

Start free trial

Tracking and reporting

See what happened to every campaign and every contact.

Open and click tracking

Turn on open and click tracking per template. Use the default HTTPS tracking domain or your own tracking subdomain.

Start free trial

Campaign reports

Sends, opens, clicks, replies and bounces per campaign, trends over a date range and each contact's activity, with export to Excel or PDF.

Start free trial

Honest numbers

Sent means the receiving server accepted the email. Inbox placement of campaign emails is not measured.

Start free trial

Good to know

What MailRush.io does not do, so you can plan with confidence.

  • Each campaign sends from one email account. To spread volume, run campaigns from different accounts; there is no account rotation within a campaign.
  • There is no A/B testing tool. Use spintax and compare results between campaigns.
  • There are no built-in CRM connectors. Connect your CRM through Zapier, webhooks or the API.
  • Attachments cannot be sent in campaigns, Inbox replies or through the API.
  • Email warmup and hosted MailRush email accounts are not available during the free trial.

See it working on your own campaign

Connect your own email accounts and try MailRush.io free for 14 days, no credit card required. Warmup and hosted email accounts come with a paid plan.
