Instantly alternative
An affordable Instantly alternative for teams that use the core cold email workflow.
If you use Instantly mainly for campaigns, inbox rotation, warmup, replies, and basic reporting, MailSequence offers a focused Google/Microsoft-first workflow with a lower monthly starting price and defined capacity limits.
Choose by operating fit
Which platform suits the workflow you need?
Choose MailSequence when
MailSequence is a good fit if you already have domains and Google Workspace or Microsoft 365 inboxes, you run campaigns for yourself or clients, and you want a leaner tool focused on the daily outbound workflow.
- You mostly use campaigns, rotation, warmup, and replies.
- You send from real business inboxes on owned domains.
- Software cost matters: yours or your clients'.
- You want to test the migration with one campaign first.
Move on your timeline
Evaluate MailSequence with one working campaign before moving the rest of your operation.
- Check source compatibility before transferring records.
- Reconnect and verify business inboxes separately.
- Confirm suppression records and sending limits.
- Move additional campaigns after the first launch is stable.

FAQ
Frequently asked questions
Can I import my Instantly campaigns automatically?
Start with a read-only compatibility check using an authorized Instantly API key. We confirm the campaigns, sequence content, leads, and block-list records exposed by the current API before promising an automated transfer.
Do I need to reconnect every inbox?
Imported account metadata does not transfer mailbox credentials. Connect existing Google Workspace or Microsoft 365 inboxes through OAuth, or purchase configured business inboxes in-product.
Can I keep the same sending limits?
Document the current limits, then recreate or reduce them during review. Exact source settings may not map one-for-one, and MailSequence readiness and plan limits remain authoritative.
Should I pause Instantly before migrating?
Keep the source subscription and campaign available while you review the imported setup. Avoid sending the same recipient from both systems; choose a controlled audience for the MailSequence pilot.
Can MailSequence help with my first campaign?
Yes. Migration help can review source compatibility, the transferred campaign, inbox connections, suppression data, warmup, and conservative sending limits before launch.
Start with one campaign.
Keep Instantly running while we verify the records that can be transferred and review the resulting MailSequence setup.
