Instantly Alternative: Alienmail vs Instantly
How is Alienmail different from Instantly?
Reviewed by Ankit Dangi, Founder & CEO · Prices checked 27 Oct 2026
The short answer
Instantly is a flat-plan sender: $47 a month for up to 1,000 contacts and 5,000 emails, with warmup included. Alienmail charges per email, so the same 5,000 emails cost $12 and a quiet month costs $0, and it writes the campaign from your website. Instantly is the better pick if you want a lead database in the same tool or send over 60,000 emails every month.
Pick Alienmail if you send under about 60,000 emails a month, send in bursts, or want the campaign written for you.

The Core Difference
Instantly sells sending capacity by the month: you pick a plan by how many contacts and emails you need, then write and run the campaigns yourself. Alienmail sells emails one at a time and does the writing: add your website and it drafts the whole sequence, then charges 4 credits for each email it sends. One rewards steady volume; the other rewards sending only when you need to.

Alienmail vs Instantly Pricing
How each one charges
Instantly
Growth $47 a month ($37.60 billed yearly) for 1,000 contacts and 5,000 emails; Hypergrowth $97 ($77.60) for 25,000 contacts and 125,000 emails; Light Speed $358 for 100,000 contacts and 500,000 emails.
Alienmail
No plan. Each email uses 4 credits; top-ups start at $5 and the rate per credit drops at $10, $50 and $250.
| Emails in a month | Alienmail | Instantly |
|---|---|---|
| None | $0 | $47 (Growth) |
| 5,000 | $12 | $47 (Growth) |
| 25,000 | $50 | $97 (Hypergrowth) |
| 60,000 | $96 | $97 (Hypergrowth) |
| 100,000 | $160 | $97 (Hypergrowth) |
Alienmail costs less up to about 60,000 emails a month. Above that, if your list fits in 25,000 contacts, Hypergrowth is cheaper. Mailboxes cost extra on both: $2.50 each a month if you buy them in Alienmail.
Cost reality: a small team's month
A founder sends to 1,000 new leads a month, 4 emails each: 4,000 emails.
Instantly
Growth fits, at $47. In month two, the next 1,000 leads take you past Growth's 1,000-contact cap unless you delete last month's, so many teams move to Hypergrowth at $97.
Alienmail
16,666 credits from a $10 top-up: $10. Month two costs another $10, whatever the size of your list.
Cost per 1,000 emails
- Instantly Growth, fully used: $9.40 per 1,000 emails ($47 ÷ 5,000).
- Instantly Hypergrowth, fully used: $0.78 per 1,000 ($97 ÷ 125,000).
- Alienmail: $2.40 per 1,000 from a $10 top-up, falling to $1.20 from $250.
So: Alienmail is cheaper per email than Growth, and Hypergrowth is cheaper than Alienmail when you use most of its 125,000 emails.
Deliverability and Mailboxes
Warmup
Both include warmup on every mailbox you connect, at no extra cost. Alienmail also warms the mailboxes you buy from it.
List verification

Verdict: Alienmail or Instantly?
