Set up accounts for multichannel outreach

This guide explains how to set up the email and LinkedIn sender accounts you'll use for multichannel outreach in Snov.io.

Snov.io Campaigns let you combine email and LinkedIn actions in one sequence, so you can reach the same prospect through both channels and increase your chances of getting a reply.

To run outreach effectively, you need sender accounts connected and configured the right way for both channels. Once this setup is ready, build your multichannel sequence using this guide.

Plan your email sender setup

Here's how to create a setup focused on deliverability, safety, and easy scaling.

Domains

Create separate domains for outreach. This protects your main domain and makes it easier to scale.

For domain age:

Buy domains at least 30 days before using them in outreach. New domains need time to build sender reputation.

For domain extensions:

Avoid spammy domains and stick to these: .com, .org, .net.

Mailboxes

For email accounts, we recommend Google Workspace and Microsoft 365.

To use provider matching, set up mailboxes from both providers. The recommended ratio is 2 Google senders per 1 Microsoft sender.

Sending emails within the same provider inboxes can improve deliverability. Snov.io automatically detects the provider your prospects use.

Number of accounts

Use the recommended limits to plan how many domains and mailboxes you need based on your target volume. This keeps your infrastructure sized correctly for stable deliverability.

Distribute mailboxes across multiple domains and create up to 5 mailboxes per domain. Putting more than 5 on one domain increases the risk of the entire domain being flagged as spam.

Domains: as many as needed

Mailboxes: up to 5 per domain

Daily sending limit per mailbox:

• Gmail: 15 emails/day → up to 30–40 emails/day after warm-up
• Outlook: 5 emails/day → up to 30–40 emails/day after warm-up

To reach 1,000 leads with 2–3 follow-ups in your first month, you need 10 mailboxes across 2 domains, plus 1 backup domain.

Start with 1–2 active domains for sending, and keep the backup mailboxes on warm-up. When you're ready to increase volume, backup accounts are already prepared and can be added to rotation immediately.

From month two, contacting 1,000 leads requires 4–5 mailboxes, so you can grow your list without expanding infrastructure.

Add email accounts

There are two ways to add sender accounts in Snov.io:

• connect your own email accounts
• purchase Done-for-you mailboxes

Choose the option that matches your current needs and resources. Sender account slots are unlimited in Snov.io, so you can connect as many accounts as your outreach volume requires.

Connect your own accounts

Use this option if you already have outreach domains and mailboxes, or if you want to buy and configure them yourself.

With this option, you manage the technical setup yourself: configure DNS records, tracking domains, and check domain health.

Go to Email Accounts and click Add email account to connect your existing mailboxes.

You can connect:

• Google Workspace accounts through direct sign-in
• Microsoft Outlook or Microsoft 365 accounts through direct sign-in
• other providers through SMTP/IMAP

Create two separate connections for the same mailbox: one via API for campaigns, one via SMTP for warm-up or advanced settings.

For Gmail and Outlook accounts, use:

• API connection for campaign sending
• SMTP connection for warm-up, or when you need advanced settings, such as sending from an alias or tracking replies on another address

Learn more about API and SMTP connections in this guide.

Set up Done-for-you accounts

Use this option if you don't have domains and mailboxes yet, or if you want to avoid manual setup. DFY accounts are useful when building a sender system from scratch or adding more accounts to your existing one.

With this option, you get preconfigured sender accounts with 100% domain health. All technical configuration is handled for you, including SPF, DKIM, DMARC, MX, and tracking domains.

Go to Domains to buy domains and create mailboxes in bulk. You can set up multiple accounts during one setup.

Done-for-you accounts are technically prepared, but they still have no sending history. Warm them up before using them in campaigns.

Prepare email sender settings

Before sending emails, make sure each mailbox is configured properly. The right settings will improve deliverability and protect sender reputation.

Control daily sending limits

Start with our recommended limits. Lower sending volume helps new or recently added accounts build reputation gradually and reduces the risk of emails landing in spam.

Recommended daily campaign limit per mailbox:

• Gmail: 15 emails per day
• Outlook: 5 emails per day

The goal is not to send as many emails as possible from one mailbox. Your prospects will only see the emails that reach the inbox, so safe limits and gradual ramp-up matter more than volume.

For new accounts, warm-up is required before campaign sending. Start with low campaign limits and increase them only after the account builds a stable sender reputation.

If you’re adding accounts already used in outreach, you may use a higher limit, up to 30 emails per day, but only if the account has healthy deliverability results.

To edit the daily limit in bulk, go to Email Accounts, select the accounts you need, and click Edit on the quick actions panel.

Add custom tracking domain

If you plan to track opens or clicks, set up a custom tracking domain to replace the default one.

Tracking in emails affects deliverability. Use it only when open or click data is important for your sequence logic or reporting.

In Done-for-you accounts, the tracking domain is preconfigured. In accounts connected manually, you need to set it up yourself. To add a custom tracking domain to your existing accounts, go to Email Accounts, select accounts, and click Edit.

Note on Gmail warnings: Custom domains make tracking safer and reduce the risk your emails will be flagged as suspicious, but they can't hide tracking completely. Gmail and other providers can detect tracking pixels and display a suspicious banner regardless of the domain used.

Check domain health

Before sending campaigns, check domain health for every sending domain.

Go to Email Accounts, click Edit next to the account, then open the Domain Health tab and run the check.

A domain health score of 75% is the minimum acceptable level to start campaigns. A 100% domain score is recommended. If there are any missing domain records on your existing mailboxes, fix them before warm-up and outreach.

If you use Done-for-you accounts, all DNS records are preconfigured. Still, check domain health before campaign launch.

Set domain forwarding

If you've created separate domains for sending, set up forwarding on each of them. Recipients may check the sender's domain in your emails, and forwarding ensures they are redirected to your main website.

How to set it up depends on how your accounts were created:

• Your own domains: configure forwarding in your domain provider's DNS settings
• Done-for-you accounts: set up forwarding directly in Snov.io under Domains

Warm up and check deliverability

Start warm-up right after connecting your accounts. Warm-up builds sender reputation through a gradual sending increase and positive engagement signals like opens and replies.

Both new and existing accounts need warm-up. We recommend running warm-up before launch and keeping warm-up active during campaigns.

Initial warm-up duration:

Run each account through the initial warm-up period before starting outreach. Do not launch campaigns during this time.

• 2 weeks to reactivate an account after a pause
• 4 weeks for new domains and new accounts before campaigns

Warm-up after outreach starts:

Don't stop warm-up once your campaign is live. Keep it running alongside your campaigns at all times.

Note that warm-up emails count toward your provider's daily sending limit. After the initial warm-up period, lower the warm-up daily limit to 10–20 emails to avoid exceeding the recommended total limit.

Add accounts to warm-up

To start warm-up for a single mailbox, go to Email Accounts and click the warm-up icon next to the account.

To launch or resume warm-up in bulk, select accounts using the checkboxes and click Start warm-up in the top panel.

Make sure you have available warm-up slots. The number of accounts you can warm up simultaneously depends on your plan.

Use quick launch option to start warm-up without any manual setup. It automatically picks the right preset based on your account's sending activity.

Progressive warm-up:

For new accounts or accounts that have been inactive. Gradually ramps up from 2 to 40 emails per day

Steady warm-up:

For accounts actively used for outreach in the last few months. Maintains a fixed daily warm-up volume of 40 emails per day

Advanced warm-up

For more control, go to Email Warm-up to configure warm-up manually. Advanced settings let you fine-tune warm-up for your specific needs:

• Premium sender pool — warm up using business domains only, for higher-quality engagement signals
• Targeted warm-up — improve inbox placement with a specific provider: Gmail, Outlook, or others
• Email template warm-up — warm up specific email content to improve its inbox placement before sending campaigns
• Custom tracking domain warm-up — build reputation for tracked links to reduce spam filter risk

Deliverability tests

After warm-up, check account performance using the Deliverability Check.

Deliverability tests help confirm that your sender is ready for real outreach. The tests simulate real sending conditions to give you insight into expected deliverability.

You can run quick tests with generated content or run a real campaign simulation with your real content for more accurate results.

In the test results, you'll get personalized recommendations for better deliverability and guidance on troubleshooting issues that may affect your results.

Use the sender only if the results are healthy. If the spam rate is 5% or higher, keep this sender on warm-up and don’t use it in campaigns until results improve.

Prepare accounts for LinkedIn Automation

LinkedIn Automation adds another channel to your sequences. You can use it to automatically build up engagement with leads through LinkedIn.

LinkedIn works best as a supporting channel for email. It creates more touchpoints and helps you follow up with more chances for a reply.

To use automation safely, prepare your LinkedIn profiles first and connect them to Snov.io.

Fill in LinkedIn profile

Make sure your LinkedIn profile looks complete.

• professional profile photo
• strong headline
• detailed About section
• filled Experience section
• company information
• profile details that highlight what you do

Build up account activity

Start with some manual activity to warm up the profile organically and improve the SSI score. New or inactive profiles are more likely to get detected for using automation.

To get started safely:

• make posts 2–3 times per week
• comment on 3–5 relevant posts every day
• connect with people from your industry
• view and engage with relevant profiles

Connect LinkedIn accounts

To connect LinkedIn accounts, you need LinkedIn slots. Add one LinkedIn slot for each profile you want to connect.

Snov.io supports LinkedIn account rotation: using multiple profiles to distribute prospects automatically.

One account can cover sending around 100 requests per week. If you plan to scale LinkedIn reach to 200–300 requests per week, you may need two or three profiles to distribute the activity safely.

If you work as a team in Snov.io, Team leaders can purchase LinkedIn slots under the Team admin account and assign them to members.

Configure LinkedIn Automation safety 

These settings help reduce detection risk and make LinkedIn outreach safer for your profile.

Location and time zone

To avoid detection, automation should match the account’s regular location. We provide a secure proxy for the location you specify during connection. You can also add your own proxy settings for full control over IP address management.

Go to the full guide on LinkedIn accounts.

LinkedIn action limits

LinkedIn Automation limits in Snov.io have two options: fixed and flexible.

Fixed limit is the default setting for all connected LinkedIn accounts. Specify the maximum number of actions of each type your profile can perform daily.

To avoid account restrictions, start with a limit that fits your SSI score. A higher score reflects a stronger profile reputation and means it can safely perform more actions.

Snov.io automatically tracks the SSI of each connected account. Check your current score in LinkedIn account settings. As you run outreach, monitor it to know when it’s safe to raise the limits.

Read full guide on recommended LinkedIn limits.

Flexible limits

Performing the same number of actions every day can look repetitive to LinkedIn and be detected as automated.

To make your activity look more natural, enable Flexible limits. Snov.io will randomize the number of daily actions within a range you set.

To activate it, use the toggle in your LinkedIn account settings and set a minimum and maximum for each action type.

See our recommended flexible limits by SSI score.

LinkedIn profile warm-up

Sending too many connection requests right away can trigger restrictions on your profile. Warm-up mode prevents this by increasing the limit gradually.

Turn on Warm-up mode in your LinkedIn account settings. The daily number of requests will increase automatically.

Specify the settings like this:

• starts at 2 requests per day
• increases by +1 every day
• until it reaches 20–30 requests per day

Once this setup is ready, you can build your multichannel sequence with email and LinkedIn actions. Sequence structure, email copy, messages, scheduling, and report monitoring are covered in the next guide.
