CENTILIO PULSE / SELL · EMBER

Looking for a Constant Contact alternative? Start with the free plan that is not there.

Historical comparison from Fable’s September 2026 research, not a current vendor quote. Confirm current provider features, prices, currency and billing periods. Pulse is unbuilt. Constant Contact bills Indian businesses in US dollars, so their figures stay in dollars here and ours are in rupees. They have no free plan at all — a trial only — and their paid tiers start at $12, $35 and $80 a month at the smallest contact tier, rising as your list grows. Send allowances are a multiple of your contact count and going over costs $0.002 per extra send, billed automatically. Centilio Pulse is free for 1,000 emails a month with unlimited contacts, ₹799 for 25,000 and ₹1,599 for 100,000, and when you hit the ceiling the send pauses and asks rather than billing you.

What moving from Constant Contact will take.

Choose Constant Contact if

You want somebody on the phone, you value the events and surveys being in the same product, and you are a traditional small business that would rather pay a bit more for a familiar tool with human support. Those are legitimate reasons and we will not talk you out of them.

Choose Centilio Pulse if

The bill rises every time the list grows, the overage charges arrive without being asked for, or you want cold outreach on the same list rather than a second subscription.

  1. Export the suppression list first. Everyone who ever unsubscribed or complained on Constant Contact, before anything else. Emailing a past unsubscriber is the worst first send you can make, and it is the mistake this migration produces most often.
  2. Authenticate before you import. SPF, DKIM and DMARC verified on the new tool, so your first send is not also your first experiment.
  3. Start with your best segment. The people who opened something recently. A first send that gets read and answered establishes the new setup; a first send to the whole list establishes the opposite.
  4. Proposed approach: authenticate first, preserve suppressions, and increase volume only as relevant delivery and complaint evidence supports it. There is no fixed warmup or migration duration that guarantees inbox placement.
Questions

About switching.

Is Centilio Pulse a Mailchimp alternative?

Historical comparison from Fable’s September 2026 research, not a current vendor quote. Confirm current provider features, prices, currency and billing periods. Pulse is unbuilt. For a business that wants campaigns, sequences and outbound on one list, yes — and with unlimited contacts instead of a price that climbs as your list grows. For a Shopify store that needs product-feed automation, no; that is Klaviyo.

Is it a Klaviyo alternative?

Historical comparison from Fable’s September 2026 research, not a current vendor quote. Confirm current provider features, prices, currency and billing periods. Pulse is unbuilt. For a business that is not an ecommerce store, yes. For one that is, Klaviyo is genuinely the best product in that niche and we would rather say so than sell you a year of disappointment.

Is it an Instantly or Smartlead alternative?

For a business that also sends a newsletter, yes, and it is the only tool on this list that does both on one list and one reputation. For an agency running high-volume outbound across dozens of domains, no — they are built for that and we are not.

Is it a Brevo alternative?

Historical comparison from Fable’s September 2026 research, not a current vendor quote. Confirm current provider features, prices, currency and billing periods. Pulse is unbuilt. It is aimed at the same buyer, and Brevo is the only large vendor that already prices the right way, by emails sent rather than contacts stored. Our argument is that they then charge extra for removing their own logo and sell SMS credits separately, and that replies going onto a customer record is worth more than either.
