Connect BigCommerce
Connect your BigCommerce store and the emails your customers send to your store’s support address arrive in Replyco as tickets; Replyco also imports your store’s orders, and your replies go back to the customer by email, from your own address. The connection has two parts: you give Replyco the credentials of a BigCommerce API account, and you forward your store’s customer emails to an address Replyco creates for the account. Replyco only reads from your store: orders, products and customers.

DNS changes can take a few hours to take effect, so you can continue and verify later in the account’s Email settings. For an address on a public mailbox domain, such as gmail.com, domain authentication is not available and the step only offers Continue. See Mailbox by forwarding for what the record does.

What happens next
Section titled “What happens next”The account appears on AdminAccounts; to check how its sync is going, see Accounts. Every email your email host forwards to the Replyco address becomes a ticket; Replyco checks the address for new mail about every five minutes, and emails from before you set up forwarding are not imported. To check that it works, send a test email to your store’s support address and wait for the ticket in TicketsNot Resolved. To reply to it, see Answer a ticket.
Replyco imports the orders created in your store in the last two days, with the products in them, then checks for new orders every few minutes. They appear in ToolsOrders; see Orders. When a message arrives, Replyco reads the first number in its subject that is not a date as an order number, and shows that order beside the ticket: a subject such as Question about order 1043 brings up order 1043.
Your replies go out by email from the Display Email address, with the Send Name as name, through Replyco’s mail server. Once the DKIM record is verified, Replyco signs them for your domain, so strict recipients such as Gmail and Microsoft accept them.
