All Features
MailerBit gives you the tools to send individually personalized, data-driven emails at scale — with no technical complexity.
Recurring Campaigns
Schedule email sends on repeating dates — the 1st, 15th, last business day, or any custom day of the month. Once configured, campaigns run automatically pulling the latest data from your contacts.
Learn more →Custom Fields
Define unlimited per-contact data variables without a fixed schema. Text, integers, floats, dates, currencies — any business-specific value becomes a dynamic merge tag in your templates.
Learn more →Template Editor
A visual drag-and-drop editor with dynamic merge tags. Insert placeholders that get replaced with each recipient's real data at send time. Built-in math expressions and filters — calculate totals directly in the template.
Learn more →Deliverability
Domain verification with DKIM and Return-Path DNS records, plus automatic warm-up scheduling. Your emails come from your own domain — with isolated reputation never shared with other senders.
Learn more →No account or credit card required.
Frequently Asked Questions
Do I need coding skills to use MailerBit?
No coding is required. The visual drag-and-drop template editor lets you design personalized emails and set up dynamic merge tags without writing a single line of code.
How many custom fields can I add per contact?
Unlimited. You can define as many custom fields as your business needs — text, numbers, dates, currencies — and use them all as dynamic merge tags in your email templates.
Can I send emails from my own domain?
Yes. MailerBit supports full domain verification with DKIM and Return-Path DNS records. Your emails are sent from your own domain with an isolated sender reputation, never shared with other senders.
How do recurring campaigns work?
Recurring campaigns send automatically on a repeating schedule — for example every 1st of the month, every last business day, or any custom day. Each run pulls the latest data from your contacts, so personalization is always up to date.
What file types and sizes are supported for attachments?
MailerBit supports attachments up to 25 MB per email on all plans. You can attach any standard file type including PDFs, spreadsheets, and images.
