How to Migrate from Instantly to SignoFast in 2026

Migrating from Instantly to SignoFast is a deliverability project as much as a software swap. The goal is simple: keep domains healthy, preserve your best sequences, and land on unlimited email economics. SignoFast runs unlimited email accounts, leads, sends, and warmup at $39/mo ($32/mo billed yearly), with LinkedIn as $30/mo per LinkedIn account.

This 2026 guide walks through a safe Instantly cutover. Reconnect Google Workspace, Microsoft 365, or SMTP mailboxes, import the leads you have permission to contact, turn on warmup, and rebuild sequences in SignoFast. Migrate one workspace or domain cluster at a time so deliverability stays stable.

Migration overview

1. Export from Instantly

• Export active leads and completed-campaign audiences you still need.
• Export or screenshot suppressions, bounced addresses, and do-not-contact lists.
• Copy winning subject lines, first lines, and sequence structures.
• Note mailbox providers and daily send rates that were healthy.

2. Reconnect mailboxes in SignoFast

Reconnect Google Workspace, Microsoft 365, or SMTP mailboxes, import the leads you have permission to contact, turn on warmup, and rebuild sequences in SignoFast. Migrate one workspace or domain cluster at a time so deliverability stays stable.

Prefer OAuth for Google Workspace and Microsoft 365. Use SMTP/IMAP for custom hosts. Confirm SPF, DKIM, and DMARC still point correctly on each sending domain.

3. Turn on warmup before volume

Do not pause Instantly and instantly spike volume in SignoFast. Overlap warmup windows. Raise daily sends gradually after placement looks healthy. Unlimited warmup on SignoFast makes this easier as you add mailboxes.

4. Rebuild sequences

1. Rebuild the highest-ROI Instantly campaign first.
2. Map follow-up delays and stop-on-reply rules carefully.
3. Add LinkedIn steps only if they were already part of the motion.
4. A/B test one variable at a time after cutover.

5. Import leads and suppressions

Import leads you have permission to contact. Apply suppressions before any send. Spot-check samples for role accounts, free inboxes you do not want, and outdated contacts.

6. Cut over replies to Unibox

Train the team on SignoFast Unibox SLAs before pausing Instantly. Positive replies that sit unanswered burn more pipeline than a late migration date.

Agency tip: client-by-client

Agencies should migrate one client workspace at a time. Prove deliverability and Unibox habits on a friendly client, then roll forward. White-label and roles keep client views clean during the transition.

Common mistakes to avoid

• Raising volume on day one without warmup overlap.
• Forgetting suppressions and re-emailing bounced leads.
• Migrating every client the same week.
• Leaving replies split across Instantly and SignoFast with no owner.

Bottom line

A clean Instantly to SignoFast migration protects domains first and sequences second. Export carefully, reconnect and warm early, rebuild winners, then cut over Unibox. Reconnect Google Workspace, Microsoft 365, or SMTP mailboxes, import the leads you have permission to contact, turn on warmup, and rebuild sequences in SignoFast. Migrate one workspace or domain cluster at a time so deliverability stays stable.
